Lab Assault summary

Lab Assault is a challenge part of the Tinkerer's Lab Mission Pack DLC pack. It takes place in the Tinkerer's Lab.

Instead of defending, the heroes must attack and destroy four Eternia Crystals. The map features a static collection of opposing defenses and enemies and offers a few different routes. Players must destroy the crystals and defeat the boss under a time limit to clear the mission.

Gameplay[]

Towers have very high health and attack damage. After destroying the four Eternia Crystals, a boss fight with 20 powerful EVs begins. They will roam the lab in search for the heroes and fire spreadshots at them up close. These shots deal high generic damage on hit.

The enemy EVs are prone to jump off ledges or behind entrances which can lead them to positions where they cannot be attacked.

Rewards[]

  • Series EV 1.5 Costume
  • Series EV 1.75 Costume (Nightmare Hardcore)
  • Random accessories and other equipment.

Dungeon Defenders Redux[]

The lab challenge has some balance changes and a quality-of-life addition in Redux: ememy EVs appear on the minimap. On Ascension, if they fall off the map, they teleport back onto it rather than die instantly. Timers have been raised on all difficulty levels. Like other assault missions, most pets are now functional.

Clearing the challenge on Ascension yields two accessories per hero instead of one, and the range of possible accessories is extended.

Notes/Tips[]

  • As with most assault challenges, certain hero abilities are disabled: Invisibility, Phase Shift, Battle Leap, etc. Redux adds the Wheel O' Fortuna to this list.
  • Almost all ranged attacks are restricted to a maximum distance of about 2–3 meters. You will be within range of enemy towers before you can attack them yourself. The higher your projectile speed stat, the more range your projectiles will have.
  • Pets do not attack or apply any in-battle effects to heroes. This restriction is lifted in Redux.
  • Projectiles from the, Plane Gun, Dragon Slayer 2000 and Genie's Scimitar are unaffected by the range restriction.
  • Mana and Purity Bomb do not get reduced range. This makes the mage abilities useful for decreasing the time taken to beat the challenge.
  • Contrary to popular belief, a BF Drill is not required to complete Lab Assault. Any appropriately built character can dominate the challenge even on Nightmare.
  • In Redux, even if Hardcore/Ruthless Mode is enabled, heroes who join during the boss fight will spawn in, as long as there are spare lives.
