Paladin master of shadows

Simple Q & A
1

AMR is telling me my 895 arcane relic has master of shadow: 1000 avoidance
The in game tool tip says 500 avoidance

Using best in bags, it’s telling me a 910 relic isn’t better than the 895 relic. Would that be because of the +500 avoidance it thinks I’m getting? What can I do?

The spell tooltips come from wowdb, for some reason the spell data shows 1000 avoidance. We model it as 500 in the simulator and when ranking gear.

Awesome, thank you so much.
