Concept here is to use DPS summoners as a sort of fireball tower stand in. Oil traps will make the fire-based DPS pets do double damage, shrine also adds DPS dmg boost. Traps at each spawn, then a central build of mortars to blast away everything as well. If it cooks fast enough, this could be a decent Tier 2 option.
1 Summoner with Huntress/monk pets, 2 DPS summoners with Fire-based DPS pets at each hint 5 (I used lil Cruisers and Mini Mechs), 1 summoner with cat and jester guardian pets
Overall speed matched my other survival build...so no real solid change here.
