Use Human Tanks to stun adds, and it will stay up the whole 8 seconds

SKs, as many of you already know, Hex is your best friend. It casts just a little bit slower than Hate, and builds a decent amount of Flyff Penya aggro, plus the added side effect of less P.

Def to eat through. Plus, if you have the fortune of a melee party, it'll help their HP regen if you have a healer/buffer with Vampiric Rage.

At high levels, Lightning Strike can be used to paralyze and disable one mob for two minutes - very useful when you have multiple adds.

Human Tanks, 90% of the time, don’t use Shield Stun on the mob you're currently attacking. Learn to use your stun as an 8 second melee sleep. Use it to stun adds, and it will stay up the whole 8 seconds.

This is very helpful when dealing with magic resist, sleep/hold resist mobs. That usually gives you enough time to kill the mob you're currently fighting, thus reducing the number of mobs you have to fight.

Make sure to save Ultimate Defense for especially dire situations. Having a few mobs on you, even four or five, is not a problem as a tank if you have a good shield-defense position.
