As the title says.
Rugged: Reduce incoming damage by 6%
Resist Frost: Increses Cold Resistance by 1575. Increases maximum Health by 3%.
Robust: Increases Health recovery while in combat by 30%.
I personally think they have no use at all.
There are almost no "Cold" attacks in the game.
The damage reduce gets less and less the more damage mitigation u have. (That isnt much anyway, i dont see )
Health recovery... i mean... ok, that might be ok.
Since im known for beeing an idiot i'd love to hear ur opinion.
Post if u think they are fine or need improvement and what you would suggest!
