Rubinite Boss Tier List
Last updated: August 2026
Learning-Curve Tiers (First Clear)
Lower learning curve: Bound Man / Undying practice, The Beast, Gravekeeper. Mid: Dual Cultist, Martyred Angel, first Guardian Faye. High: Plaguebearer, Faye Rematch, The Ghost, Roy the Hunter. Peak first-route: Witch Alcina phase two. True route peak: Red-Eyed Tree under one-hit rules, Dark Ruby, Puppet Master, Blood Moon Alcina.
Tiers measure first-clear friction, not no-hit prestige. Talisman access and Explosive Strike timing can move individuals down a half-tier.
Community Notes
Steam reviews still cite post-Faye spikes — that maps to Mana Sources + rematch, not a single secret superboss. Deck Verified play does not change tier order but punishes 40 Hz lag on high-tier fights.
