Or something worthwhile like guarantees weather effects.

COR doesn't deal in guarantees. The closest I could see COR getting here would be increasing the proc rate for the matching element and decreasing the proc rate for the "losing" element by, say, 4% on an unlucky roll, 8% on a 1, etc. up to 40% on a lucky roll and 44% on an 11. A bust, of course, would mean that for the COR, the bonus never happens and the penalty always does -- potentially a bummer for Quick Draw.

Of course, there's also the thought of "enhances weather effects" meaning increasing the damage bonus/penalty from it, possibly on 1.5 times the rate of Wizard's Roll to make up for the randomness. Or even a mixed thing -- increase/decrease proc rate by 2% per and when it procs increase/decrease by half the effect of an equivalent Wizard's Roll. -- Pteryx
