A resourceful spellcaster draws upon experience to lend power to their magic. In the same way many of the spellblight conditions offer advantages under the right conditions, at the GM's discretion, the standard conditions described in the core rules can provide benefits as well. If the following material gives a spell failure chance, this is in addition to other rolls to succeed at casting (such as caster level checks and arcane spell failure from armor) and is resolved after those rolls.
Bleed: While a spellcaster is affected by this condition, their inflict wounds spells inflict an extra point of damage per die. This only applies when using an inflict wounds spell to inflict harm, not when using those spells to heal undead.
Blinded: A blinded spellcaster can use some of the energy of a spell with the light descriptor to try to counteract the blinded condition. Also, when a blinded spellcaster casts a spell with the light descriptor, they can choose to take a 20% chance of spell failure with that spell. If the caster successfully casts the spell, the spell also ends the blinded condition.
Confused: While confused (either temporarily, or permanently by way of an insanity spell or effect), a spellcaster can tap into that confusion during periods of lucidity. When a confused spellcaster can act normally, the DCs of their spells that give confusion or insanity effects are increased by 1. The caster also gains a +2 competence bonus on caster level checks made to bypass spell resistance with those spells.
Entangled: A spellcaster who is entangled and casts a spell with the force descriptor can choose to take a 20% chance of spell failure on that spell. If they successfully cast the spell, they end the entangled condition, or if they are anchored, their movement is no longer prevented, but they are still entangled.
Dazzled: A dazzled spellcaster can use some of the energy of a spell with the darkness descriptor to try to counteract the dazzled condition. When a dazzled spellcaster casts a spell with the darkness descriptor, they can choose to take a 20% chance of spell failure with that spell. If the caster successfully casts the spell, the spell also ends the dazzled condition.
Deafened: A deafened spellcaster can use some of the energy of a spell with the sonic descriptor to try to counteract the deafened condition. When a deafened spellcaster casts a spell with the sonic descriptor, they can choose to take a 20% chance of spell failure with that spell. If the caster successfully casts the spell, the spell also ends the deafened condition.
Disabled: A disabled spellcaster can tap into their fears of impending death to empower their conjuration (healing) spells. Once per day, while disabled due to damage taken, a spellcaster can choose to treat a single conjuration (healing) spell they cast on themselves as having a caster level two levels higher than their actual caster level. They must actually cast the spell; this ability cannot raise the caster level of a spell cast from a magic item.
Grappled: While being grappled, a spellcaster can choose to take a 20% chance of spell failure when casting a touch attack spell. If the spell is successfully cast, the caster gains a +2 bonus on the attack roll against the creature grappling them.
Nauseated: A nauseated spellcaster can use some of the energy of a conjuration (healing) spell to try to counteract the nauseated condition. When a nauseated spellcaster casts a conjuration (healing) spell, they can choose to take a 20% chance of spell failure with that spell. If the caster successfully casts the spell, the spell also ends the nauseated condition.
Poisoned or Sickened: Once per day, while a spellcaster is poisoned or sickened, she can take a 20% chance of spell failure when casting a single spell that causes a poison or sickened effect. If the spell is successful, the DC of any poison or sickened effect granted by that spell increases by 2.
Shaken: While a spellcaster is shaken, once per day they can channel their fear to increase the power of a single spell with the fear descriptor that he or she casts. When they do so, the spell DC of that spell is increased by 1. They must actually cast the spell; this ability cannot raise the caster level of a spell cast from a magic item.
Staggered: Once per day, while a spellcaster is staggered, they can take a 20% chance of spell failure when casting a single spell that takes a swift or standard action to cast. If the spell is successfully cast, they can take a move action directly after casting the spell.
