Run the combat waves on a DPS huntress.
Stats - Level 90 with trans gear from NMHCMM Prom+ or Mass HC Campaign Act 1 Siren drops
Wave 1 - Auras in each lane
Wave 2 - Traps in each lane
Wave 3 - Spike Blockades
Wave 4 - Gas Traps for corner copters, ensnare auras for south copters, extra inferno in south lanes
Wave 5 - Upgrade 1 or 2 levels on auras, walls and inferno traps
The build phases will be pretty tight with timing, you'll need a bit of practice and good movement to get everything down.
Hint 1 - These are safe spots that you can snipe anything on the map from with a DPS huntress. I pretty much live on these walls during the combat phases. Spiders and dark elf warriors won't target you if you're on these walls.
Hint 2 - Doubling up on spike blockades adds an extra layer of security for if one goes down during wave 5 or the boss fight
Optional for the build - Swap some of the doubled up walls out for darkness traps near the south crystals to help with spiders. Also maybe swap the extra inferno traps and some of the doubled up walls for enrage auras in the south lanes or the northeast and northwest lanes.
During the boss fight: Prioritize Copters and Djinn first. Once they are down, it's safe to ignore the Ogres and focus on the boss. Just drop a quick upgrade on any walls that are low between boss phases if you get the chance. If not, having 2 walls helps a lot. The Ogres aren't worth the time it takes to kill them, it's much faster to just upgrade the wall they are beating on to keep them occupied.
