At the end of a short or long rest, choose a damage type. Until your next rest, reroll any 1 on damage dice for damage of that type. You must use the new roll, even if it is another 1.
Whenever you cast a spell, you can cause an unknown archival power to wreathe you until the end of your next turn. While this power is present, any creature within 5 feet of you at the end of your turn or their turn takes 1d4 damage of the damage type chosen after rest (reroll does not apply).
Any creature killed by rerolled damage or wreathe damage is claimed by the Archive.
