Artificer
Spellcast Trait: KnowledgePlay the Artificer if you want to support your allies by crafting magical items for them.
Magical Items: You can give your Sparkcraft Items to an ally, and they can use them the same way you can. When a Spellcast Roll is required to use the slotted ability or spell, you make that roll.
Synchronized: When another PC activates your Sparkcraft Item you can spend 2 Hope to make a Tag Team Roll with them. This special Tag Team Roll does not count toward your limit on initiating Tag Team Rolls.
Positive Feedback: Every time another PC activates one of your Sparkcraft Items, you gain a Hope.
Signature Item: You have one additional Sparkcraft Item slot and take one additional domain card of your level or lower from a domain you have access to. Then permanently slot one spell or ability into one of your Sparkcraft Item slots.
A Sense of Power: When Positive Feedback triggers, the PC who activated the Sparkcraft Item also gains a Hope.
Mastercrafted: Every time another PC activates one of your Sparkcraft Items, they can roll with advantage for their next action. (Their next action might be part of the item activation itself.)
