Job Abilities:
Blood Weapon lvl 1, interval 2hours, duration 30 seconds
-Drains your targets HP during melee attacks notes on blood weapon
- In my opinion Dark Knights get shafted on the 2-hour. It sounds really good at first, but do not rely on it to save your party. The best time to use this 2-hour is if you have 50% health and you know the mob is decimating your party. Do not wait till you have 10 healths because you will die before even hitting and draining the mob's health.
-Good to use against the monster family bombs, evil weapons, cardians, and Elementals. Last Resort level 15, interval 5 min, duration 30 seconds
-enhances attacks but lowers defense
-What no one will tell you is that last resort has a built-in provoke. And it doesnt lasts long as berserk. If you have a warrior sub, use berserk instead. Kessen 99 confirms that last resort does stack with berserk. Also best used before a weapon skill to maximize damage.
Weapon Bash lvl 20, interval 5 min, duration none
-Delivers an attack that stuns the monster, you need a two-handed weapon. To gain enough cheapest Final Fantasy Gil is necessity in the leveling processing; it will save much of your cash.
-Finally a great job ability. This attack blows away last resort and berserk, and can be stacked with either. Last resort and berserk will do an extra 5 dmg or so, Soul eater will do an extra 50 level. This attack is HP
dependant, so the more Final Fantasy Gil you have, the more damage it will do.
