Effect

These descriptions are for the ultimate ability unless specified otherwise. The goal is not to add a fourth level of the ultimate, but more focused for extra utility, but some ults would be too strong or have less room for improvement so I added a some non-ult effects.

It gives all purpose stats like trinity so it could not be the best substitute for AD or AP items.
