Fixes for assassin shadows

[rrra]

Few suggestions:
1. Fix whatever bug causes shadows to disappear if you run too far away from them.
2. Either prevent shadows from casting mind blast or remove the conversion chance from it. The stun is sufficient cc in any situation. The conversion is just annoying, especially when you can have up to 7 shadows casting it all at once right now.

# 1 I assume is the same problem as with Necro summoner, maybe Druid too, when you move too far from summons while they're attacking for example they will die/disappear.

I heard it's a hardcoded issue and can't be changed, but maybe Game can think of something.

# 2 Could probably nerf the conversion, or remove it and boost the stun a little.

I like conversion for speedrun crucible aka Mind blast
