Does anyone use STR potions?

I dunno, but I've sold them for a ton of cash, so...

I never use them,I use vitality portion.

I think they're quite good. The cd is long, but just think of it as a one time cooldown.
Use it with all your cooldowns and it's very potent.

There's usually some point in the fight where you want that damage buff in particular.
I only wish the mats were less costly. Still worth it imo, though.
