The small present is a placeholder for damage totem.
With the addition of Radioactive Coal, which drops 1 per account, we're heavily incentivized to run this map in multiplayer. The fastest runs will be achieved in 2p (since you won't have fewer splits on w7-13 needlessly increasing mob counts and HP), but 4p is more fun :)
Have someone drop the app mana mid-wave so that the build can be completed wave 1.
Tower + initiate boost every wave. Use Genie Scimitars for more consistent mana collection, since enemies do not get close enough to the stack for chicken baller/stone throw spear to be reliable. Scimitars may also be desirable on upgraders for the same reason, despite it being technically inferior for genie swirling.
Boss wave: run 1 barb, 1 dps/hero boost monk, and double boost. Barb facetanks boss with turtle stance + hawk on cooldown. Monk hero boosts and stays at range (to avoid getting webbed) with a pet such as airplane.
Optional turbopaper variation: drop the north and south str drains, reduce phys beam to 3du, and add an electric aura and an extra lightning tower to center stack. The phys beam is technically optional, but I didn't have anything better to use 3du on, since ensnares synergize quite poorly with initiate boost. This build requires semi-active dps on north and south cores to avoid losing to electric-immune trash mobs, and further requires a quick boss kill. For reference, I lost to an electric-immune orc on south core on boss wave, despite having successfully killed the bosses a mere second prior. Don't be like me. Use the """safe""" version.
