I'm wondering if there is a state of diminishing returns with resilience after a certain point? I currently have 436 resilience, I'm thinking about changing my current enchant on my chest +150 health to the +15 resilience, but I'm wondering if there is some sort of cap beyond which resilience doesn't help anymore.
