Welcome to the Royal Defense trophy guide! is a classic tower defense game where you have to defend your castle from the troll hordes while following the story of the dwarven kingdom’s eternal struggle against the trolls.
Play the game normally trying to get as many stars as you can while doing all the levels, then prepare yourself for an intense grinding session.
Step 1: Play the game while attempting to get three stars for every level
During this stage, your main quest is to complete all the sixty levels of the game trying to acquire all the three stars in everyone. There are three campaigns in the game and each of them contains twenty levels. To earn all the stars on a level, you don’t have to take any damage to your castle. In case you fail, you can replay every level later.
The three campaigns are:
- Forgotten Fields;
- Snowfall Mountains;
- Desert Bones.
The levels will get harder and harder to complete as you proceed but you will unlock new towers and spells too. Each spell has a cooldown time that needs to end in order to reuse it. Spells and towers can also be upgraded using gems which you will acquire as a reward from completing a level, so save them in order to get good upgrades and don’t waste them.
At the end of this step you’ll be earning these trophies:
Step 2: Get three stars on every level
During this stage, you will replay all the levels where you haven’t got the three stars in the previous step. Remember that in order to get the three stars, you must avoid any damage to your castle.
There are a total of 189 stars in the game:
- 180 stars from the main levels;
- 9 stars from the Forgotten Field campaign (Heroic mode).
See the Tips section and the Tactician trophy of this guide in order to get more details on how to ease this step.
During this step you’ll earn these trophies:
Step 3: Grinding trophies
This will be the last but longest step for this game. Here you need to replay a single level or more than one level in order to collect kills, summon and sell towers to get the last three trophies of this game.
At the end of this tedious step you’ll earn the following trophies:
- At the beginning of every wave, you can pause the game in order to plan your best strategy and complete the level without any trouble. You can speed up the game too to make every level even faster but make sure to be prepared to push away every wave first;
- The dart towers (stun upgrade) and the mines (radar tower upgrade) are the best buildings of the entire game so make sure to fully upgrade them with the gems.
- Save around 100 gems or more for the Heroic levels on the Forgotten Fields campaign or you will need to use real money or restart on a fresh save to manage these levels;
- You can earn up to twenty gems for each level if you finish it with all the three stars but, unfortunately, you can get them just for one time each level. You can also earn 100 gems by replaying the first level of the Desert Bones campaign, 100 gems by beating the first Heroic level in the Forgotten Fields campaign, and 20 gems for the second and the third levels;
- For the Heroic levels, immediately pause the game and use the gems to buy and fully upgrade a Mine (radar tower for 13 gems in total), two or three Dart Towers (stun towers one gem each and eight each for a full upgrade). Then begin the level and buy/full upgrade the other dart towers and mines with gold;
- Don’t waste your gems upgrading your castle health because to get the Tactician trophy your castle can’t take any damage so having any extra health is useless. Use them instead to fully upgrade the mines, dart towers and the two spells (Meteor rain and Deadly Swamp);
- The best level to farm kills for the Commander trophy is the seventeenth level of the Desert Bones campaign;
- Near the end of every level, pause the game and sell all the towers except one or two that are on the enemy road in order to speed up the grind for the Merchant and Architect trophies. You can buy and sell repeatedly the dart tower which is the cheapest one until you run out of gold.
Build 50 towers
You will get this trophy while progressing through the game. However, every level has more than ten building spot. See the Architect trophy to get more details on how to build and sell towers faster.
Below is a table with every tower and its upgrades:
|Dart tower: it shoots very fast and can damage flying enemies||The second upgrade of the dart tower: it shoots faster than the basic one.||One of the two last upgrades of the dart tower: it stuns ground enemies. The best and most useful upgrade of the game.||One of the two last upgrades of the dart tower: it causes a lot of damage and it slows the target enemy.|
|Cannon tower: it has an average range and does a little more damage than the dart tower.||The second upgrade of the cannon tower: it has an improved range and damage.||One of the two last upgrades of the cannon tower: the machinegun is very fast and it’s great against groups of enemies.||One of the two last upgrades of the cannon tower: the sniper tower has a huge range and a strong single shot but it’s slow.|
|Artillery tower: it has a wide range and it’s good against packs of enemies.||The second upgrade of the artillery tower: it has a wider range and increased damage.||One of the two last upgrades of the artillery tower: the rocket tower has a much longer range than the artillery one.||One of the two last upgrades of the artillery tower: this tower sets the ground on fire causing damage to the nearby enemies.|
Build 50 mines
You will get this trophy while progressing through the game. However, mines give you gold so always create at least one per level when you unlock them in order to get tons of gold and upgrade all your towers.
|This is the basic mine. It produces gold over time when placed.||This is the second upgrade of the mine. It produces more gold and it’s faster than the basic one.||This is one of the two last upgrades of the mine.
The radar tower produces a lot of gold and supports nearby towers by increasing their range and strength.
It spots hidden enemies too.
|This is one of the two last upgrades of the mine. The teleport tower brings back the enemies at the beginning of the road.|
NOTE: Always upgrade them into the radar tower (the third image) because this is the best upgrade and is really useful especially in the last campaign in order to reveal all the hidden enemies.
Sell 50 towers
To get this trophy, you have to sell a previously built tower and repeat it fifty times. You will need to sell 500 towers for the Merchant trophy so pause the level near the end to sell all the towers and start grinding for this trophy. Make sure to leave some towers in order to finish the level. You can build and sell a tower repeatedly until you run out of gold (see Architect trophy for a detailed explanation of this method).
Kill 500 enemies with spells
You should earn this trophy normally during the game if you often use them but due to the little effectiveness of these spells, it’s better to only grind the kills when you have upgraded them in order to not fail a level.
There are a total of five spells:
|METEOR RAIN||It spawns a meteor rain above the enemies.|
|DEADLY SWAMP||It spawns a poisonous puddle under the enemies.|
|FROST NOVA||it freezes the enemies stopping them on their place.|
|EARTHQUAKE||It causes an earthquake that does a lot of damage.|
|HEROISM||It boosts the towers’ damage and range. (kills done with boosted towers are not counted for this trophy).|
You should use these spells in every level when aiming for the three stars, but unfortunately, they do a little damage so make sure to upgrade them wisely (Meteor Rain and Deadly Swamp are the best to get more kills with single use and to unlock the Ruthless trophy).
Kill 1000 enemies
You will earn this trophy while playing normally. See the Commander trophy for more details on where to farm kills. Shown below is a table with every type of enemies you will face in the game:
|WORG||He’s fast but he has little health. There is a stealth version too which is invisible until he approaches a radar tower.|
|SCOUT||he’s as fast as the Worg but he has more health.|
|TROOPER||He’s pretty slow but has a lot of health.|
|HEALER||He heals nearby enemies.|
|SHAMAN||He can summon tiny and fast enemies and he can disable nearby towers. Kill them as fast as you can.|
|CHIEF||He’s a tough enemy due to his high health and supports other enemies on the battlefield.|
|SUMMONER||He drops three little, deadly and fast enemies when he dies.|
|ICE TROLL||He’s very tough and immune to stun effects.|
|WYVERN||He’s a weak flying unit. There is a stealth version too which is invisible until he approaches a radar tower.|
|STONE TROLL||He’s very tough and immune to stun and teleport effects.|
|DRAGON||He’s a flying unit and he has a lot of health.|
|MUMMY||He’s a stealth enemy and he hides the nearby enemies too making them invisible and invulnerable until they approach a radar tower.|
NOTE: You will encounter tier 2 enemies at the beginning of the “Snowfall Mountains” campaign and tier 3 enemies at the eleventh level of the same campaign. They are the same enemies but they will have more health than before.
Kill 3 enemies with one spell
To get this trophy, you must kill three enemies with a single use of a single spell.
You can use all the spells you have (except for the Heroism one) to achieve it, but the best are:
- Meteor Rain;
- Deadly Swamp.
Make a complete improvement for 50 towers on the levels
This is another trophy that will come naturally while playing because you will always need to upgrade your towers in order to defeat the hardest waves of enemies. When you build a tower, you can upgrade it for more coins. Buy all the available improvements for fifty towers and you will unlock this trophy.
Fully upgrade any tower in the store
Unlike the Armorer trophy, the upgrades needed for this trophy are displayed in the shop section of the game. In order to access it, from the beginning screen press to play and in the campaign selection screen press .
To get this trophy you need to upgrade at its best a single tower by using gems. Every tower has three sections:
- Damage – it increases the amount of the damage a tower inflicts;
- Range – it increases the distance of the sight that a tower has;
- Cost – it decreases the cost of gold needed to build a tower.
Each section has six steps and every step increases in cost. Once you have fully upgraded all the three sections for a tower, the trophy will pop.
Build 1000 towers
You should have built 500 towers more or less at the end of the game if you build a tower on every building spot on every level. However, the quickest and cheapest way to grind this trophy and the Merchant one at the same time is to fully upgrade your dart tower cost with gems in the shop section of the game, redo a level until the last wave, pause the game, select a building spot and repeatedly build and sell a dart tower.
When you reach a total of 1,000 towers, the trophy will pop.
Sell 500 towers
To get this trophy easily, check the method mentioned in the Architect trophy because it’s really hard that you sell a tower on purpose
Kill 30,000 enemies
This will be the last trophy you will earn because of the huge number of enemies required. The Desert Bones campaign is the best place to grind out the kills as most of the levels consist of 7/8 waves of enemies. The best and easiest level where to farm kill is the seventeenth if you only want to replay the same level numerous times.
Complete all levels to 3 stars
This will be the “hardest” trophy of the game if you are not really prepared. There are 189 stars to earn in the game:
- 180 stars from the main levels (twenty levels each campaign);
- 9 stars from the Forgotten Field campaign (Heroic mode).
Remember that in order to get the three stars, you must AVOID any damage to your castle.
To ease this trophy remember that the dart tower (stun upgrade) and the support tower (third upgrade of the mine) are your best friends, so put all the gems in these tower upgrades. Budget and loot upgrades are really useful too.
The first campaign is easy as it will introduce you to every type of enemy and to every type of tower. At the beginning of the second campaign, the game will introduce you to the tier 2 enemies that are the same enemies but with more health and at level 11, it will introduce you the tier 3 enemies that are even stronger. The final campaign is the hardest one as it will introduce stealth enemies too. These will appear transparent on the screen and they will be invulnerable to towers’ attacks until they approach a radar tower (third upgrade of the mine) or get damaged by a spell.
The best strategy is to to build your radar tower in the middle of the map so it covers most of the paths and towers, giving you good support and enough time to kill all the enemies and only build dart towers (stun upgrade) to kill all the ground and flying enemies. Remember to use your spells to give extra damage, but save them for the final wave as it will be the hardest one.
Some tips for each console specifically:
- If you play on PS4, leave the Heroic levels for last as they are insanely hard.
- If you play on VITA, you don’t need Heroic levels for this trophy.
Save around 100 gems or more for the Heroic levels on the Forgotten Fields campaign or you will need to use real money or restart on a fresh save to manage these levels; to pass them without any effort, immediately pause the game and use the gems to buy and fully upgrade a Mine (radar tower for 13 gems in total), two or three Dart Towers (stun towers one gem each and eight each for a full upgrade). Then begin the level and buy/full upgrade the other dart towers and mines with gold.
When you get all the three stars in every level, you will unlock this trophy.
