When you use Infusion of Power, the creature you target with it gains +1 rank of Warding per Tier until the start of your next turn if it does not already have a Warding effect on it with greater remaining DR.
When you use Infusion of Power and grant a creature Warding, you can spend 1 charge of Mana Flux to increase the duration of the Warding effect to 1 minute, instead of it ending at the start of your next turn.
