Sustains with turn based cost need immediate FIX

[Bormoth]

Used both. Osmosis shield is pretty awesome, in fact better then block and works ok with blocks. Spend turn to activate pretty strong buff sounds valid. Same with Rain again used it too pretty much aoe lighting storm from lighting mage. If you want always run with shield then why not use regen ring demons, would make taking vim per turn rings useless would it? Those on hit are good when you hit alot, while on being hit is awesome with body wretchling armor and summons.

Also momentum is really strong buff(And speed buffs in general, you spend turn or by that moment fraction of turn to get more actions per turn, Inflates into more actions per turn really fast, and momentum also lasts as long as you can handle, and if you can afford stamina gain items and from talents(which is only reason to take it if you think about it) even better.
