My Zero ST:
for PVP and is VERY EFFECTIVE
1. HP Orchid (for st**id players who keeps running or if you're suffering from Fatal)
2. Frost Force
3. 3ple Bash (for evasion purposes)
4. Break Through (Frost Force + Break Through = 1 kill *Depends on your and enemy's level or stats)
5. Gashing Sword? (I don't remember the skill name, the one when he plunges his sword to the ground then spikes will appear) this skill is essential when you failed with your FF + BT tactic and your enemy will try to grab you (use this skill while you're still in invincible state from using a previous skill), OR when your enemy's MP runs out from spamming 1st skills and you're near him, using this skill + Grab (if your that of a PRO) is very effective.
