Lucky Token

A Lucky Token is obtained when you roll a natural 20 on a skill check. You can only have one of these tokens at a time.

This token has multiple uses:
 * You can use the token to get one reroll on any attempted roll (except damage)
 * You can choose a specific element table when rolling for bending scrolls
 * You can trade the token with other players
 * (more uses will be added)
