===Magic===
Magi can cast any arcane spell, and Clerics any divine spell, with a spell level equal or below 1/2 their class level, rounded up. They have access to all arcane spells in the SRD spell list.

Casting a spell of any kind costs Hit Points. The cost is 1 + double the level of the spell being cast:

{| border=1 cellpadding=10 cellspacing=0
|-
!Spell Level
| 0 || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9
|-
!HP Cost
| 1 || 3 || 5 || 7 || 9 || 11 || 13 || 15 || 17 || 19
|}


This loss cannot be healed normally but is recovered after 8 hours rest. There is no need to memorize spells in advance. Just because a character can cast any spell, doesn’t mean that they should. Choose spells that suit the character. Select one ‘signature’ spell per spell level from 1st upward that they prefer to use over any other. These spells are easier to cast due to familiarity, costing 1 less HP to use.

The Difficulty Class (DC) for all spells is 10 + Caster Level + Caster's MIND bonus
