Thunderbird Tuft (Major)
Activate Cast a Spell (add 1 action)
This carved chunk of amber contains a single tuft of gray feathers, which spark with electricity to create an odd jittery sensation in anyone holding the amber for long. When used as part of a Shocking Grasp spell, thunderbird tuft funnels electricity back into the spellcaster in a defensive nimbus. For 1 minute, any creature that touches you or that hits you with a melee unarmed attack or non-reach melee weapon attack takes 3d4 electricity damage, or 3d6 electricity damage if the creature is using a metal weapon.
Traits
Items that have the catalyst trait are consumable material spell components that alter or magnify specific spells. Activating a catalyst is part of Casting the Spell. The catalyst might increase the number of actions required to Cast the Spell, as indicated in the catalyst's Activate entry. Additionally, the spell gains the manipulate trait if it didn't already. Because the catalyst becomes part of the spell, you can draw the catalyst as part of Casting the Spell.
An item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
