Stabby Boi(cap 180 halberd/assassin build)

Disclamer: Dragon Tooth Halberd is better.

Assassin stab is a very conditional skill to utiilize, so while setting up the skill, you need to find a filler, in this case its strike stab. Dekoi is needed to optimize the performance, altough you can make do with wcos.

Skills:
-wcos(lvl 10)
-quick aura(whatever lvl you want
-Decoy Shot(whatever lvl you want)
-Chronos Drive(lvl 10)
-strke stab(lvl 10)
-assault attack(lvl 10)
-assassin stab(lvl 10)
-Backstep(lvl 10)
-foresight(lvl 10)
-arcane strike(level 1 or 6)
-shukuchi

Stats:
Str>Agi>some Vit
(Alternate)
If you could get yourself a sacred ice spear, you can go with INT instead of AGI since it has 100% atk up from int, the INT would also increase you chronos drive extra hits' damage

Combo 1(500mp):
Assault attack>strike stab(smite)>impact(cons)>chronos drive(smite)>closer
Use this combo as your main DPS combo.

Combo 2(400mp)
Impact>backstab(smite)>closer

Combo 3(100mp):
Backstep>arcane strike(save)
Use this to get behind the enemy to unleash your assassin stab. You can just use quick aura to cancel out the arcane if you don't want to trigger it.

Gears:

Weapon: Tolerancia, elemental halberd, Sacred Ice Spear with gwamol xtal
Sub-hand: fallen angel dagger(atk% and cdmg% ) lil empress dagger(crit and evasion), chocolate knife(tumble unavailable)
Armor: FC 18 armor with ornlarf or ifrid or both
Additional gear: Bear Hat with baphomela
Special Gear: machina ring/mustal with seele zauga and venena

Strike stab has crit penalty of 50%, for both base and % crit stat.
Without the penalty your crit would be:
25(base)+22(FC18 arm)+10(empress dagger)+10 (critical spear&critup)+15(bear hat)+15(seele zauga xtal)=97 crit

With crit penalty it would be reduced by 14 crit so you'll have 83 crit for strike stab, use food buff to make up for it.

Don't have level 4 skill yet?
Just use a simple impact>strike stab combo with wcos as your way to recover mp. Assassin stab is just there for the sake of it anyway. Not that worth it to use 40sp+ for the skill, actually.

 

Lol i like it!! looks fun to play. I only tested with arcane strike and utterly ignored backstab .-.

 

Well, this build is pretty much created for the sake of it. The idea is while you wait for chronos drive's extra hit to give you some mp. You can set yourself for a Backstab or do some auto attacks. Strike stab is abnormally strong for a T3 skill, with decent crit its a spammable skill comparable to buster blade, or even better
