To clarify, BV triggers when a "hit" occurs, so high defense/awe/vine shield, etc. will make BV not trigger that much. High protection, mistform, & regeneration is what you want for maximum BV triggers, basically you want to get "hit" a bunch with the hits not doing that much to you. Not sure about luck & etherealness (my guess is they keep a hit from occurring), but it seems like BV triggers when mirror images are hit.
