I don't actually know, and I can't find the info anywhere on the Minecraft Wiki :/
Yeah, that is a good point. But I think the point of you being so powerful still stands, cause hopefully the reason you survived this long is because you know how to take out groups.
The main issue being that if there ARE a limited amount of Lingering Potions, the other Golems they make will be useless :/
Mostly that part is opinion based, and I AM glad its not a ripoff.
I still think its fairly complicated to be a Golem, but thats just me.
If this makes it, I'll be surprised, but not disappointed
