here's how the run works, firstly with some ground knowledge: • Yuki is spawned when the player uses a chain grenade (the red and white smashball looking pickup) to blow up a Statue of Gambling. • Statue of Gambling is one of 12 statues that can spawn in the first stage. Statues spawn at 1.00 mortality, roughly 34 seconds at the earliest • chain grenades have a chance (yet undetermined, but it's unlikely when the player is missing health, bombs, or there is a lot of loose XP) to spawn from debris, the first opportunity at around 0.8-1.0 mortality (28 seconds at the earliest). this sets a lower bound on the run time. • Yuki has a whopping 105,000 HP on Overdrive 5, which would take nearly 15 minutes of landing every single core shot at 2x speed, and a couple of minutes even with a highly stacked early game DPS build, so i looked for a way to circumvent her wall of health, using the skill Stack Overflow. • Stack Overflow works as follows: whenever your kills ("MURDERS" in the bottom left of the UI) is a multiple of 100, your next attack does 10,000 damage, with an internal cooldown on the effect of 2.147 seconds. so long as you don't kill anything, you will continue to do 10,000 damage. a regular core shot does 10 damage, for reference. • unlike bonus boss 1 (ghost), spawning yuki does not delete other enemies, although most of them are usually taken care of by the grenade. this prevents us from waiting until exactly 100 kills before triggering the fight. enemies are also semi-randomly despawned when offscreen for too long, and sometimes spawn in the middle of an ongoing chain grenade explosion, so waiting for exactly enough enemies left to equal 100 kills is prone to failure. • the Void Scream skill does 1 damage to nearby enemies and enormous knockback when the player takes damage knowing all that, the plan is as follows: 1. starting the run, pick only passives or weapons that are aimed and do a small amount of damage. look at the 4 starting zone choices, and reset if there's no statue of gambling. 2. start killing souls slowly, leaving as little experience on the floor as possible. keep an eye on MORTALITY, getting ready to line up a debris with the statue (you can't move very far after picking up the grenade before it explodes). reset the run if the debris contains anything other than a grenade. • watch the MURDERS and the HORDE numbers in the bottom left. once the sum of these two is a little above 100, we're clear to blow up the statue. we now have an angry Yuki who wants us very dead. prepare to dodge for your life. reset the run if there are no longer enough enemies to reach 100, or if you go over. • begin extremely carefully picking off the remaining enemies one at a time. pause if necessary. get that sweet '00, and then aim at Yuki. once you hear the stack overflow proc, IMMEDIATELY damage yourself to activate Void Scream, sending all the remaining enemies far offscreen. Stack Overflow must be on cooldown, or the nomimal 1 damage the skill does to ememies will be increased to 10,000. continue to load all bullets into her so they don't hit anything else. she melts 😊 (WIP)
