Shillien Knight guide

Your class is focused on cubics, and it's the cubics that make you a wonderful Fighter; without them, you're just a low-HP tank. The downside is that cubics are expensive; you have to summon three or four to get through an hour's play. The plus is that they can't be hit and give you help in attacking and debuffing.

Poltergeist Cubic, the first cubic available (at Level 40), could well be the best. It is cheap, costing two D Crystals at Level 1, three at Level 2, and four at Level 3, and it is a huge help. It debuffs your target's P.Atk, P.Atk Speed, or P.Def (and might end up debuffing all three before the fight's over).

Vampire Cubic, the second cubic (at Level 40) isn't half as economical as the Poltergeist Cubic. While it can be argued that the HP Drain spell it casts can save you a heal, it really isn't worth the cost in D Crystals (six at Level 1, seven at Level 2, eight at Level 3). Use this cubic only in PvP or very hard fights.

Venom Cubic, is your third and final cubic (at Level 49). Like the Poltergeist Cubic, it is very cheap (three D Crystals at Level 1, four at Level 2) and rather useful. Its poison spell works often, and though it doesn't do that much damage, anything is a help.

Note that even if you get resurrected, you lose your cubics when you die.

Corpse Plague isn't really the most useful of spells, because of how fast corpses disappear and how long the spell takes to cast. It's nice to have every now and then, but it isn't worth its weight in SP.

Even though you have low HP and P.Def, as long as you stick with white monsters and have a nearby healer, you can handle tanking. Once you get into yellows or big groups of whites, though, it'd be better to

step aside for an Avenger to tank while you debuff.

Open up a fight with Hex or Power Break; they work pretty often, and when they do, they decrease the monster's P.Def by 15% (Level 2 Hex by 20%) and P.Atk by 15% (Level 2 Power Break by 20%), which makes killing much easier.

Lightning Strike, a spell you get at Level 58, is a must have indeed! It's a high-damage spell (power 1046) but even more importantly it has a chance (though small) of paralyzing your target for 2 minutes. It's a gamble, but if you paralyze someone in a duel or a hard monster on a hunt, you just gave yourself 2 minutes to hack away at him.

Where Hate pulls one monster onto you, Hate Aura pulls all monsters around you to attack you. This is very good when a Cleric or a Rogue type finds herself being chased by leaders or a group spawn.
