So this is probably a stupid question but can you equip a hammer to a character with Worthy in their keywords? Like for instance can you equip Angrir with Mokk's Hammer? My guess is no since from what I read he already has a hammer attached.

One. He doens't have the hammers automatically attached.
2. Yes of course you can.

They don't already have relics attached to them, but they do create relics when they die.

Alrighty. That makes sense. Thanks guys.
