[Barb] Does Double Swing produce mana?

Hi there,

on the net I can find info that Double Swing from lvl 10 onward cost -0.x+ mana (like -1 mana at lvl 17).
Does it work? I mean, does it produce a mana with every hit?

I recall reading that it’s a display bug and you can level it high enough to have zero mana cost, but it never actually starts producing mana on it’s own. I don’t believe I’ve ever tested it though

If you have mana leech then yes, dbl swing becomes a positive net mana generator.

This is why HC or barbs who play safe usually put a 1 or a few points into it for mana burn enemies.

It doesn’t produce mana, but at level 9 DS doesn’t require mana. After level 9 the scaling is irrelevant. It’s not a bug or anything, it just scales negatively per level, opposed to it being programmed to stop scaling when hitting lvl 9.
