My AST is so weak, why?

It's not "rather", you need both Benefic I and II, plus you shouldn't even need to be spamming Benefic II regularly. It likely means you are having a harder time because of your weapon. AST guild vendor sells an i115, even though its NQ it'll work for leveling until you get a better drop.

This. Benefic I is your go-to heal. Benefic II is your "wow he got hit really hard" heal. You should only need to use it infrequently.

WAR has higher self healing capabilities than DRK. So you actually may have been making the WAR run for their money if you were still using the outdated weapon.
