Each caster has a Power Pool rating based upon their level. This represents several things:
- The maximum Power Cost of any single spell that the caster can cast safely.
- The amount of Power the caster has remaining to cast Natural Magic spells.
Casters can “overcharge” spells, that is, they can cast a spell that costs more Power than they have Power Points (either in total or remaining). Doing so can carry real danger for the caster, up to and including death or the temporary or permanent loss of casting ability. Some of the danger can be offset by casting through a focus attuned to both the caster and at least one of the effects used in the spell.
Overcharge Rating = Power Cost of Spell – Current Power Pool of caster – Focus Power Rating (if used)
If a caster overcharges a spell, the player will roll 2d10 and apply the following modifiers:
2d10 – Overcharge Rating + Focus Rating
So if a character with a current Power Pool of 10 casts a 15 point spell, their Overcharge Rating is 5. The Overcharge Effect roll would be 2d10 – 5. If they cast through a 2-point Focus, their Overcharge Effect roll would be 2d10 – (5-2) or 2d10 – 3.
|2 or below||Death. The resulting overcharge of the spell kills the character instantly|
|3||Burned out. The character survives, but burns out their ability to cast spells permanently. Nothing short of a wish will bring this ability back. Character drops to 0 hit points and must make Death saves as normal.|
|4-6||Drained. The overcharge drains the caster’s ability to cast spells for as many days as the spell’s Overcharge Rating. The character gains the Unconscious state.|
|7-10||Temporarily drained. The casters Power Pool is drained completely and does not begin recharging again for 1 day. The character receives the Stunned condition for 1 hour.|
|11-14||Worn out. The caster receives two levels of exhaustion. The spell drains triple the normal amount of drain. The character receives the Stunned condition for as many rounds as the spell’s Overcharge rating.|
|15-17||Tired. The caster receives one level of exhaustion. The spell drains double the normal amount of drain. The caster receives the Incapacitated condition for as many rounds as the spell’s Overcharge rating.|
|18-19||Incapacitated. The caster receives the Incapacitated condition until their next turn.|
|20||Unscathed. The caster receives no ill effects from casting the overcharged spell.|
