Arcane Tomes

This ability allows you to write spell books. With spell books you can prepare and "slot" spells that you would use often. You can slot spells depending upon your Arcana. With each slotted spell you can prepay its Soul Cost. Then when you use the spell the cost comes from the spell book and not you. This allows you to have spells ready and refill your Soul. Furthermore the spell slot tier can increase or decrease a spell's casting speed as the casting speed will be set at the tier it is slotted for. The spell's casting power depends. If it is slotted in the tier the spell belongs to, it does not change. For every tier level less than the original tier level, the spell's healing/damage power decreases by 20%. For every tier level greater than the original tier level, the spell's healing/damage power increases by 10%
