Golden Dragon's Bounty [one-action] Feat 8Archetype Spellshape Source Tian Xia Character Guide pg. 116
Your familiar alters the material of a spell into that of a precious metal. If the next action you use is to
Cast a Spell that deals bludgeoning, piercing, or slashing damage, that damage is your choice of
cold iron,
silver, or steel for the purposes of weaknesses, resistances, vulnerabilities, and the like. At 14th level,
adamantine is added to the list of metal choices. The spell gains the
metal trait.
Traits
Archetype: This feat belongs to an archetype.
Spellshape: Actions with the spellshape trait tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
