The one that gives 30 tp per tp regain tick is nice you would have a standard 50+30 tp per tick and if you have the trait it would be.. 50+30+25???? I dont know the real numbers but it would work really well, you could consider the insta 300 tp item as 3rd additional skill and the 30 extra tp per tp tick as extra extra trait. If you play for example tank in frontline it really becomes useful
