Add Spirit Catalyst

Hello,
On the Amulet you can have Implicit and Explicit bonus to Spirit.
I wonder why is there no Quality Catalyst that would increase the number?

My small Early Access feedback would be to add spirit catalyst or add spirit bonuses to one of existing catalysts.

I feel minion masters are limited to using only defensive catalysts (for LIFE/DEFENSES/RESISTANCES only) compared to non-minion builds.
