go ask those guys sitting in the nexus.... they will teach u magic, after u learn it, u have to remember it, aka equip it on ur slot.

In regards to Ostrava:

There are two ways you can go about handling Ostrava. The items involved are Lune Sword, Lune Shield, Mausoleum Key, and Pure Clearstone (not sure about the exact translation of the stone, its called 純粋なみなぎ石 in Japanese; I'm going off based on the name in the Trophy list- be aware that the exact 'stone' name might be wrong)

If you kill him you can get the Mausoleum Key which will lead you to Old King Doran (it opens the door guarded by the red-eyed knight in 1-1). Where you can get other cool weapons. However, if you kill him you will miss the rarest Clearstone. Which you'll need if you want to create the highest level weapon with that stone (and receive the corresponding Trophy).

You can save him and get all the items as well, however you must save him 3 times.

He will be in:
1.) 1-1: Save Ostrava in the courtyard
2.) 1-2: Save Ostrava from under the bridge
After you beat the one of the final area boss in the other areas you will be able to go to 1-3:
3.) 1-3: Save Ostrava by the gate being attacked by two red-eyed Knights (If he dies in combat here you'll need to pick up the Mausoleum Key from his corpse or you'll miss it).

At 1-4 before the elevator you will meet Ostrava in Dark Phantom form, by killing him you will get the Lune Sword and Lune Shield. You will also get the Mausoleum Key.

Thanks to Doctor_No of NeoGAF forum for this info.

sorry... hard to keep it down when i think of world domination...

The crystals won't finish my friend. You can just use it again and again. I usually will stand right at the place when they come, give them a shock and continuously whack them till' they run. Then backstab. Haha. No harm I guess, since you'll earn loads of soul from killing them. If you lose on the other hand, just head back to the place and get your souls back.
Otherwise another alternative, play in soul form. No one can PK you.
