Spell Tinker Two ActionsFeat 16

Source Pathfinder Core Rulebook

You've learned to alter choices you make when casting spells on yourself. After casting a spell on only yourself that offers several choices of effect (such as resist energy, spell immunity, or a polymorph spell that offers several potential forms), you can alter the choice you made when Casting the Spell (for instance, choosing a different type of damage for resist energy).

However, your tinkering weakens the spell's integrity, reducing its remaining duration by half. You can't use this feat if the benefits of the spell have already been used up or if the effects of the first choice would persist in any way after switching (for instance, if one of the choices was to create a consumable item you already used, or to heal you), or if the feat would create an effect more powerful than that offered by the base spell. The GM is the final arbiter of what Spell Tinker can be applied to.



Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.


An action with this trait requires a degree of mental concentration and discipline.


This indicates abilities from the wizard class.
