Casting spells from scrolls

The following is not a house rule, but since we had trouble finding it the other day...

 

When casting a (higher level) spell from a scroll, the chance of failure is


(Minimum caster level needed to cast spell - character level) * 5%

So for example, if you are 5th level and try to cast a 7th level spell.

(15 (min. level needed to cast 7th level spells) - 5) *5% = 50% chance of failure

If a failure happens, consult overview below

Caster level difference = 1-3 -> 95% chance of total failure; 5% of reverse or harmful effect

Caster level difference = 4-6 -> 85% chance of total failure; 15% of reverse or harmful effect


Caster level difference = 7-9 -> 75% chance of total failure; 25% of reverse or harmful effect


Caster level difference = 10-12 -> 65% chance of total failure; 35% of reverse or harmful effect


Caster level difference = 13-15 -> 50% chance of total failure; 50% of reverse or harmful effect


Caster level difference = 16+ -> 30% chance of total failure; 70% of reverse or harmful effect
