Warlock!

Finally advanced to a Warlock after days of looking for a Peacemaker. However, when I advanced to a Warlock I was slightly unsatisified at it x_x; Can anyone suggest tips, tricks and combos with the Warlock?

Warlock takes some time getting used to, no worries!
A lot of it is recoil linking.
& the timing on the melee abilities just takes practice! Keep at it ;D

Ehm, as far as warlocking goes.
Notable combos
Tornado - run to grab
Tornado - dash & z for 2 slices that throws them in the air, then up & z for lesser ifrit, they fall back into your fire bullets.
Tornado - 2 greater undines (blue bolts) followed by a grab.
If they're on the ground and you jump attack them. There's a long recoil, so go in for a grab.
Make sure you're always at the highest point when using blizzard, the range expands downward.
Tornado is great for the freeze frame and linking grabs, just like stone curse and saver.

2 bar shield is godly for 1v1~
Iunno what else to say D:
Lori's a Lire dammit!

Don't underestimate tornado. I did it to a friend and it took him 2/3 of his energy. But only a full one. So you should wait until tornado finishes before doing any tornado combo above.

Kekeke, friends don't count. They don't lag like crazy considering they live close.
With the rest of them it's lucky to even hit ;p
