Quoting SoFFacet, reply 11Actually that tactic is currently available. If you have many %chance-crit items, they stack. If they all go on the same attack, you can get several thousand damage in one hit, often head-shotting your unlucky victim.
Well, the chance of getting a 12x crit is about 1 in 2000. Not to mention that you need an artifact to do so....
10% for Ashkandor, 10% for Slayer's Wraps, 5% for cuirass. Getting just Ashy and Wraps is 1 in 100, not too bad, for an 8x Crit, but not a 1 shot by any means. (2000 damage is a lot, but only probably a third of someone's total health, maybe less, if artifacts are in play).
Cuirass puts it at 1 in 2000, but also only increases the damage to 12x. A very small comparative increase for amazingly lower odds.
