I feel this is important for the people who want defensive skills. And in any case, use health boost 3 before everything else.
If you are wondering, yes, you can stack divine blessing AND defense augments.
BUT.
It works like this: if you have both of these skills, the game will pick the higher chance to proc. If the chance to proc are equal, the game will pick the higher damage reduction.
If you have divine blessing 1 and defense augment 1, you're going to get the same result of divine blessing 2.
So, 25% chance to proc from divine blessing 1, with 30% reduction from defense augment 1.
Defense augments are good only at the lower levels, or you will sacrifice better augments like health. Use health before everything unless gunners.
PRIORITIZE DIVINE BLESSING 5.
DON'T GO FOR HIGH DEFENSE AUGMENTS.
