Having multiple summons per character would currently be over powered, and I understand why we cant do it. I think a lot of people are a little bummed out that they cant just make a pure summoner character, because 1 summon doesnt impact the fight enough to warrent a dedicated summoner, and your summoner char will constantly have excess ability points they cannot use to buff the summon, even if the buffs would help (which they dont always do anyway). Having 2 summons would be too strong at present.
So here is my idea (summons dont include totems):
1 summon = no change
2 summons = sacrifice 'X' constitution to summon (where X scales with caster level)
3 summons = get 'fractured' debuff (all resistences SET to -100% including physical, while you have 3 summons in play) or something similar that is a balanced enough penality for having 3 summons in play.
Cap summons at 3 and get increasing debuffs for each summon past the first one. So its viable to use just 1, but its also viable to use more then one at a price. If your caster dies, so do your summons, so using 3 might not always be a good idea.
I typically find that on tactician, the enemy almost never attacks my summons anyway, they use a mobility spell (or just walk past them) and go straight for the player characters. Debuffing the caster seems like a fair trade off. There is a huge number of mobility spells available so summons cant really body block, and they can easily be avoided.
Id like to know what people think about this idea. Is this a viable suggestion? Is the suggested debuff too strong or weak? What other penality would work for having 2 or 3 summons in play?
