- Hint 1 indicates the upper core placement.

- Build on upper core, the stacks are 3 LTs and 4 DSTs.

- Boost with a summ guardian, hunt + app on dst stack.

- TBoost after first wave.

- Upgrading the boost beam should be enough.

- If you are struggling you can add minions on top of the stairs and/or the sides.

Build taken from this video: Dungeon Defenders - Tomb of Etheria by Washboard.

On a side note, i do love Leberkäse.
