Converted Abiltiy: Tough

[zylosan]

The in game justification for the abiltity working as part of a larger scale battle is that the essence field of each soldier combines into a self reenforcing pattern the empower select abilities created to harness such effects.

The out of game justification is that its a lot simpler to track.

I think the usual solution for this is to sell back the benefits of Unkillable 1.

I am not sure what you mean. Could you please explain?
