Which critical ring is better for me?

With DSE, your current critical rate is 85% and crit damage range is 1.46 - 1.65, for an average of 1.555. Your current average damage is 1 + 0.85*0.555 = 1.472

With the Adventurer Dark crit ring, assuming 5% mincritdmg boost, then your average damage is 1 + 1*(0.51 + 0.65)/2 = 1.58. DPS gain is 7.34%.

With the Explorer's crit ring, your average damage is 1 + 0.95*(0.56 + 0.65)/2 = 1.575. DPS gain is 7%.

To be honest, it's not a very big difference. But since you are a Luminous, Absolute Kill is 100% crit so getting 100% crit is... quite pointless. AK is your primary source of burst DPS, and everything else is rather rubbish. It's fairly obvious that the Explorer's crit ring is better in that respect. But at the end of the day, unless you're in for a super long-drawn fight, that even 0.5% DPS increase is valuable, then I'll do the finer calculations for you.

The breakpoint total %INT on all your current equipment for a ring with 15%INT to match those crit rings is 214%INT, and for a 12%INT ring it is 171%INT. Any total %INT less than these will get you a DPS increase of more than 7%.
