You misunderstand. You use demon limb in town before battle orders and shout. You don't need to recast if you win, it lasts a long ass time.
If you prebuff you have to get body, go to town, switch gear, go to moor, BO/shout, back to town, switch gear, back to moor.
If you demon limb you get body, go to town, demon limb, then back to moor.
It's the same amount of trips to town as if you had to buy mana pots.
As for my barb, I'm currently working on getting FG for a level job
Just because I don't have my barb means I can't offer suggestions or insight?
