To refill your magic, find two sorcerers and use your special magic to kill them. Quickly get their Spell Books, and before they dissapear, use your magic again.This will trigger an error, causing the sorcerers to give you two more Spell Books!! Repeat this error/trick until your Spell Meter is full.

If you find yourself surrounded by a lot of enemies and at least one sorcerer, hit the sorcerer somehow (magic or sword), grab his magic, then immediately use it. A bug will cause the sorcerer's magic to reappear on the ground where you can repeat the process.

To resurrect your friend, simply use your magic as soon as he dies. This will trigger an error and keeping your friend alive!

Note: This does not refill his/her Hit Points, so one hit will kill them.
