Many players are broke multiple s1 items (requiem gold) never going past +10, It seems to get 10% or more break rate very early. There is a gremlin with a yes no button watching over and making sure ppl cannot reinforce s1 items). Reinforced lentus: SR 48.55%. DR 51.45%. DL 7. BR 17.20%.
From +20 and +21 if you think we are going to do anything above ordinary with these rates you can suk the big toe. Why would any single target dps want to invest in supernus jewels when you get +1 important stats to each reinforcement with both supernus and ordinary! Evasion/accuracy is the only real improvements from ordinary to supernus.
Level (requiem lant) 25 s2 weapons have 6% break rate from +29 or +30 (there are absolutely no weapon drops from level 25-40) have not tested any s2 level 40 weapons. It does not really take THAT MUCH for reinforcing , for eximius accessories it take about 96 eximius basic and 50k-70k lant for each 3 stages.
We never failed going from +0 to +11 with eximius accessories so with supernus should be way less in Requiem. (level68-71 accessories) but yeah it is stupid reinforcing them since they do not gain more stats than supernus maybe 1stats ahead of supernus and they break a lot after +11 unless of course your using insurance xeons/success rate coupons.
