Ironeye Ultimate Art Run (Everdark Libra) (Elden Ring Nightreign)

In this run you can only use Ironeye's Ultimate Art (Single Shot) To damage and defeat the Boss. It's only a boss run but it's long, timestamps below for the most important parts. So the challenge lies in building trying to build up your ultimate gauge as quickly as possible. You have to fill up your ultimate gauge all the way to even be able to use your ultimate art. You want relic's that fill up your ultimate art gauge the fastest (successful guarding fill's up art gauge, and defeating enemies fill's up art gauge are vital!) Ultimate Auto charge also work's but is not great. Single Shot is very a good ultimate art, first two shots inflicted poison for heavy damage. This fight took forever, the condemned clone had a one eyed shield and jar cannon (I was hoping he'd have a bow, and spam light weight arrows at me, to fill up my ultimate faster). So I was able to block the jar cannon as it is physical, but the one eyed shield does fire high fire damage and also was draining my entire stamina bar even though I was level 15. The jar cannon/one eyed shield also takes about 5 seconds just to get one shot off, so due to how slow he attacked me it took me about 4 - 5 minutes to recharge my ultimate art (usually takes me around 3 minutes usually). Libra also barely attack's you and stay's passive a lot, until his health is about 3/4 down he gets a little more aggressive. Libra can also buff the clones attack and defense and heals there health to full. By the end of the fight the clone had a 117+ attack power buff dealing up to 11910 damage with a single shot (jar cannon and one eyed shield). The clone at 35+ attack power was easily one shotting me. Luckily less likely to be targeted combined with his slow jar cannon and one eyed shield made it to where the other clone would distract him long enough so I wouldn't have to deal with him a lot. 0:40 Battle start 0:52 Proc'd poison and hit libra for 1449 damage 4:06 Another poison proc for 1535 damage 4:40 Phase 2 23:00 1/4 health down 51:00 half health down 53:00 Death 1, Ironeye one shots me with his jar cannon has 35% attack buff 59:40 Death 2 Ironeye ones hots me again with the jar cannon 1:02:55 death 3 one shotted again by 45% attack power buffed ironeye 1:23:00 3/4 health left 1:59:35 Death 4 (No wending graces left) 2:06:15 The Clone one shot's the other clone for a massive 7816 damage 2:06:30 Would of been the killing blow, but Libra went into his make a deal pose where he raises his hand up and hold's it there. and he takes reduced damage, he only took 182 damage, what a buzzkill (Normally I'd deal around 500 damage) 2:10:28 The clone kills the other clone for 11910 damage!! His attack power has been buffed to 117%!!! He might be able to one shot me with his bare fist at this power level! 2:11:00 Wait for Libra to get out of his make a deal pose, then finish him off with 588 damage. 21:28 Relic setup, and aftermath
