Which Rubinite boss is the hardest?

Alcina, The Witch is the hardest fight: 520 HP across two phases with 12 distinct attacks. Roy, The Hunter (500 HP, 10 attacks, including a Parry and his own Focus) is the hardest mid-game wall.

Can you fight Rubinite bosses out of order?

Mostly no. Bosses follow a linear order except for four fights after the first Faye, The Guardian battle. The Gravekeeper and The Priest are available immediately as a choice, and the other two unlock after beating them.

What changes in the Real fights?

In the Real World half of the game every attack is fatal, healing potions are removed, and boss healthbars disappear. Health upgrades are replaced with Mastery, which increases damage instead.

The one structural thing to know: progression is linear except for four fights after the first Faye battle. The Gravekeeper and The Priest are open immediately as a choice; the other two unlock once you beat them.

Illusion bosses (first 10 fights)

During the Illusionary Realm half you keep a healthbar, can carry two Healing Potions, and can see the boss healthbar. Fights are pattern-reading exercises, not one-hit checks.

* Branch point: these two are available in either order after Faye.

Real bosses (13 fights, one-hit deaths)

After the White Space sequence the rules change: every hit is fatal, Healing Potions are removed, and the boss healthbar is gone. Health upgrades become Mastery (damage). Four bosses are exclusive to this half.

Difficulty ranking

Ranked by HP, phase count, attack count and mechanics that punish mistakes. In the Real half, difficulty is execution pressure — the same attack list, but one mistake ends the attempt.

Rank	Boss	Why it ranks here
1	Alcina, The Witch	520 HP, 2 phases, 12 attacks including Execution Grab, Shadow Warp and Greatlance Barrage. The Real version has no healthbar and no potions.
2	Roy, The Hunter	500 HP and 10 attacks — and he uses Parry and his own Focus against you. The hardest mid-game wall.
3	The Puppet Master	420 HP with Earthshaker and Sweeping Grasp covering wide areas; Real-exclusive so it is always one-hit rules.
4	The Tree?	7 attacks across 2 phases, including Crushing Iris and Devouring Beam. Real-exclusive.
5	The Martyred Angel	400 HP, 2 phases. Egg Roll and Spinning Shards punish greedy punishes.
6	The Ghost	360 HP with Possession and Remanifest — you cannot see its soldier corpses in the Real fight.
7	The Plaguebearer	360 HP but only one phase; Toxic Tunnel is the trap.
8	The Gravekeeper	300 HP, single phase, but Summon Shadows adds pressure.
9	The Priest / The Dual Cultists	300 HP, one phase, telegraphed joint attacks.
10	Shadow Ruby	Mirror fight — it uses your own Slash, Focus and Strike. Short but punishes button-mashing.
11	Faye, The Guardian	200 HP, 6 attacks, fought twice as a skill check.
12	The Beast	200 HP, slow swings, the tutorial fight.
