Boxing Fights in new reno in RP doo give bonus. but you can't loose. Spoiler: the Prizefighter bonus +5% to normal damage resistance is all you het from Prizefighter title, considering you did not loose. Besides Jinxed is an ocasional triat ment for hardcore players not for an everyday playthrough. as you get over 55% chance to crit fail on a missed attack. and even with 95% hit chance you're going to miss like 1/20 of attacks. so going with something below 95% chance to hit on a jinxed build is plain loonacy. not to mention you play with low Lk, which is even more penalizing with jinxed, since you get more severe penalties from crit fails, with implication on the worst ones from crit fali list more often. As for the reno boxing ring than yes crit fail couts as a self knockout and you do loose. Jinxed is generally not a good triat to go with. But for some reason you are hell bent on playing with it, and keep complaining about it.
