Crumble Effect is a prefix that turns up on Head and Armor. It gives Crumble Effect: +3% to +4% at its lowest step, +62% to +83% at its best — and you need item level 116 before the best one can appear at all.
It comes up at weight 4 when the game rolls affixes, never doubles up with another affix that does the same job (crumbleEffect), and it is what puts Cracking, Crumbling, Fracturing, Shattering and Pulverizing in an item's name — so you might pick up a Cracking Wand.
4 Uniques lock it to a fixed number: Graveweight, The Patient Mountain, The Quarry Warden's Brow and Sediment.
