Chaos Shield

You weave an arcane sign, that flows over and around your hand as warding magic is invoked apun the touched creature or oneself. Causing a shimmering prismatic barrier to cascade over you and vanishes until you take the rolled damage types.

You roll 2d10 and choose one of the two results. The result rolled dictates the effect. If the roll is odd; gives the target immunity to the corresponding damage type in the Odd column, and vulnerability to the damage type in the Even column. But the opposite is also true for even rolls; having the Even give immunity and Odd gives vulnerability.

Example: Roll a 4 and 7. Choose 4: Gain cold immunity but fire vulnerability. Choose 7: Gain radiant immunity but necrotic vulnerability.

If both d10 have the same result; you can choose to increase or decrease one of the results by 1. If you increase it to 11 it becomes 1 and if you decrease it to 0 it becomes 10.

A creature cannot have Chaos Ward cast on it more than once at a time.
