Two questions...

[Eruntalon]

Both of these questions will make me look like a noob, but here goes:

How do you split slimes?
and
What is luck for?

[Celes152]

The higher your luck, the better chance of getting a critical hit you have.

To split slimes, rabarta works good or you can hit them with the third attack ina combo.

[hooray4punkmusic]

Hit them with magic. Or your last hit of you combo
Luck is for critical hits.
