[Provocation] Longer gain critters?

[Demoquin84]

Are there any critters, when paired up do minimal to no gain to each other? In essence gain off them two a lot longer?

I thought 2 poison ellys would work ... but they kept casting at each other and died

gamans?


lowland boras?

while they will and do damage each other they have lots of HP so you can heal them?
