I like this, maybe have it for th9+ so there is a way for them to take on th10s with those infernos, th10s already have maxed lavas and golems, so I think this will be more of a th9 thing. I did not understand the health bit though, so if you said this ignore me: maybe have the Max health increase to a certain point giving it a constant regen until that Max point, and instead of invuln maybe have it take -75% damage from infernos, and regen 10% of inferno damage to it after reaching health cap. And how about making it attract 3 streams of a multi? Again, sorry if you mentioned this.
