KMST 1.2.450 - Evolving System, Adventurer Hyper Skills, Citadel of Tyrant

FP's Hyper Attack looks like snipe with mad range, could come in useful for bossing possibly, especially that DoT damage.

As for Bishops:
Heaven's Door: 500 MP, 1200% damage to 15 targets, 8 hit, 180 sec cooldown, damage cap 9,999,999. At the same time buffing your allies. (I'm not quite sure on the buffing part.)

Vengeance of Angel: Toggle skill. Magic Attack +50, defense ignore 20%, attack speed increased by 1 stage, Angel Ray damage +20%, Angel Ray attack count +1, Restricted to Angel Ray and Teleport skills, max damage cap increased by 100,000.
