Dungeon Defenders

Completing Deeper Wells, Foundries and Forges, Magus Qurters and Alchemical Labs on Insane will unlock this trophy. You need to complete the 1st map before the 2nd map unlocks, and so forth. This trophy is stackable so if you complete Insane you will unlock the trophy for the lesser difficulties as well if you haven't done them.

This is the legend for all maps supplied in the guide. The first 5 are all names of Towers that can be built by the Squire and serve as the basis of all defenses. The last 2 - Strength Drain and Ensnare Auras are towers that can be built by the Monk which serve to improve your defenses, but are by no means a necessity unless otherwise noted.

The starting mana (from chests) and maximum defense units allowed are listed on each level. The costs for each tower are:
Bouncing Blockade: 40 mana, 4 defense units
Slice & Dice: 140 mana, 8 defense units
Spike Blockade: 30 mana, 3 defense units
Harpoon Turret: 80 mana, 6 defense units
Bowling Turret: 100 mana, 7 defense units
Ensnare Aura: 30 mana, 2 defense units
Strength Drain Aura: 60 mana, 6 defense units

Deeper Wells
Max Defense Units: 60
Starting Mana (Chests): 160
No. of Waves: 5

1. Collect Mana from the chests, then start with building Bouncing Blockades and Bowling Turrets as illustrated in the map.
2. Complete your defense with Slice & Dice Blockade (or Bouncing Blockades if you don't have it yet) and Harpoon Turrets.
3. Upgrade your Bouncing Blockades and Slice & Dice as you progress.

Foundries and Forges
Max Defense Units: 80
Starting Mana (Chests): 200
No. of Waves: 6

1. Collect Mana from the chests, then start with Bouncing Blockades covering each of the passages leading to the Crystal. Build Harpoon Turrets to backup your Blockades and deal with any Archers
2. Replace your Bouncing Blockades with Slice & Dice Blockades. Upgrade them as you progress and remember to repair any damaged ones.
3. On the last wave, you will be introduced to a single Ogre. Ogres have very high hitpoints and can deal alot of damage, quickly destroying your defenses and/or killing you if you are unprepared and outnumbered. Make sure to check the map and beef up your defenses by upgrading and repairing them.

Magus Quarters
Max Defense Units: 90
Starting Mana (Chests): 200
No. of Waves: 6

Beware, your Hero will die if you fall into the lava in this level.

1. Build Bouncing Blockades on each of the 3 long staircases leading to the middle of the map. Build a Bowling Turret behind each of these towers, facing straight downwards.
2. After the 3rd wave, you are introduced to Wyerns - flying enemy units that go directly for your Crystals. These will come from the Southeast and Southwest of the map. Build the 2 Harpoon Turrets facing these 2 directions as depicted in the map.
3. Replace your Bouncing Blockades with Slice & Dice Blockades after you have your Harpoon Turrets set up. Upgrade them.
4. Build another Harpoon Turrets to the North of your Crystal for contingency.

Alchemical Labs
Max Defense Units: 85
Starting Mana (Chests): 200
No. of Waves: 6

There are many methods to beat this level, but the underlying strategy is always the same - control the choke points. This will also be your first encounter with a Boss.

1. Start with building Bouncing Blockades, including at the "SD" location on the map above.
2. Build the Bowling Turrets as shown
3. Build the Harpoon Turrets on the elevated platform that is next to the Bouncing Blockades in the east, and place the Slice & Dice Blockade at the corner of the platform. This way the SD will protect the Harpoon Turrets and do some damage as well.
4. Upgrade and repair all your towers. Build two Slice & Dice Blockades right next to where the "Red Demon" icon is.
5. The Boss will spawn during the last wave and land right smack in the middle, as shown by the Red Demon icon. Bosses can only damage towers and heroes, but not the crystals. You can temporarily stun the boss and deal some damage by hitting the 4 Electrical Rods in the middle of the map. Remain in his line of sight and confine him to the middle of the map, or he will fly off somewhere and start damaging your other Towers.
6. During the Boss fight, an infinite amount of monsters will continue spawning from each door. You must deplete the Boss' hitpoints in order to complete and end the wave.
7. Defeating the boss will reward you with a unique weapon. It's stats vary according to the difficulty you chose.
