how could people casting different spells? since their cane?skill?wisdom?
plz tell me, i'd like to know.

well cane uses magic form the get go and as your cane skill increase you get access to different spells...click the magic tab at the bottom of the games screen to learn about it...with other weapons you have to have skill lvl at 30

another thing to note is ctrl 1~5 to equip the various spells, one at a time though. You can't do a full assault and not expect to blow the cane =)
