3 SUMMONER BUILD  --- 3 Butterscotch (or Lime Pie) and 1 Ginger Required

4 -->  Lime Pie(or Butters) and Regular +5 Huntress Guardian , stand corner of ground and stairs to agro webs on the west side -- stand a little away from the LTs and core on east side incase a wasp agros to you, they do strong splash damage). These Summoners boost 5 LTs and 1 Str Drain (huntress guardian can not boost ensnare aura so do not worry about Ginger or standing too close to auras).

5 -->  Ginger and Lime Pie/Butterscotch [stand north of 6 LT Tower Stack (Hint3) to agro spider webs away from towers]

If you have a 2nd Ginger, just put an extra LT in one of the 5LT stacks and use 2DU for reflect or something. Unlimited Power.

DARKNESS TRAPS OPTIONAL unless sharkens on west crystal are a problem, and if they are a problem still maybe a shrunken Gas trap or spider minion is needed on west crystal ramp. Or stick with darkness traps.

STILL AN UNTESTED BUILD. Tested and works fine just 47:30m combat time with sesar's set let's call this experiment a failure :prayGe:

If mobs have 175% health at 4P scaling, and 150% at 3P Scaling. And the only benefit to a 4th summoner would be 1 extra buffed LT with extra guardians (or dps pets kekw) - you still have 94% of your potential firepower --> mobs would die around 10% faster with 3P scaling. Now on the flip side, there would probably be 10-15% more overall mobs with 4P for more loot but this is most definitely 15+% faster. Same reasoning applied to say 2P is better (which it probably is).. so this is mostly just a fun meme build that hopefully works fine without darkness/gas/minions because the build time could be nutty. Now that I think about it with 2P with monk g blasted str drains that's only 10 LTs boosted (or 12 with gingers where 2 would have regular buff beamed range) and 150%(3p mob health) vs 125% (2p mob health) -- :monkaHmm: but the LT math for the unboosted towers is too much for me to care about rn tbh
