[1.2.396] Demon Slayer (2)

This is for hot time, but disregard that.
Lionheart Champion Axe, Battle Hammer.

The 3rd weapon from the left in the 3rd line.. Is that a level 140 katara?

So, he uses this instead of MP? And how does it recharge? Are there potions, or skills/cooldown?

There's this ability called Demon Strike (hits 4 times skill)
It generates Demon Force for them
And there's a 3rd job passive which allows them to gain 10 Demon Force every 4 seconds (PASSIVE)
