#	Boss	Where	Path
1	Pale	Seal of Deceit (Cave of Deceit, Adonis)	Both
2	Letter Carrier (mini-boss)	Bridge at Hades	Both (name changes by alignment)
3	Vicious (good) / Vague (evil)	Seal of Despise	Depends on alignment

5	Virulent (good) / Lady Charity (evil)	Shrine of Shame	Depends on alignment
6	Ladon	Canyon of Despair	Both
7	Osiris	Whirl of Despair (final)	Both

1. Pale

Where: Seal of Deceit (Cave of Deceit, Adonis) · Path: Both

He heals and summons weak undead until you push the three rocks onto the three switches (bottom-left, top-left, top-right). Only then does he become killable; finish him fast before the zombies wear you down.

2. Letter Carrier (mini-boss)

Where: Bridge at Hades · Path: Both (name changes by alignment)

Attack for two or three seconds, step away from the sword swing, repeat. Two or three connected swings kill an Assassin or Paladin outright at this level.

3. Vicious (good) / Vague (evil)

Where: Seal of Despise · Path: Depends on alignment

Extremely hard hitters. Open with basic attacks, spend half your SP at 50% boss HP and the rest at 25%. Bring potions and save before entering.

4. Ghost of Ladon

Where: Seal of Betrayal (the bridge) · Path: Both

Fights in a small space. He fires projectiles at range, lunges from a vanish (sidestep one tile), and turns purple after his head-slam, which is your window. Level 42, 46 or 49 armor-set thresholds make it much easier; bring 60% potions and several Origins of Life.

5. Virulent (good) / Lady Charity (evil)

Where: Shrine of Shame · Path: Depends on alignment

Virulent transforms into a dragon (level 70, 25,987 HP, 1,261 attack, 610 defense). Keep moving to dodge the screen-wide spell and the spike traps, strike right after it, and use your own screen-clearing skill. Winning unlocks the Archangel ultimate.

6. Ladon

Where: Canyon of Despair · Path: Both

Easier than his ghost. Wait for the purple (vulnerable) head phase and unload your screen-clearing skill.

7. Osiris

Where: Whirl of Despair (final) · Path: Both

The Seed of Chaos itself. Destroy both hands to bring the head down, then attack the head; the hands regenerate, so repeat. After the credits you reload before Ladon; there is no post-game.

Class notes for boss fights

Warrior: Berserk Spirit before the vulnerable window; Blessed Armor if a boss hits harder than your CON can absorb.
Paladin: Restore between phases instead of potions; Holy Bless and Holy Shout stretch the burn window.
Assassin: Keep moving. Virulent’s screen-wide spell misses a running Assassin most of the time, and Ghost of Ladon’s lunge is a one-tile sidestep.
Everyone: Save before the door. Quick save exists in the Steam version, but do not save at 0 HP: a known bug locks that save in respawn mode (see save files).

Boss questions

Who is the final boss of ZENONIA 1?

Osiris, the Seed of Chaos, fought in the Whirl of Despair right after Ladon. Break both hands to expose the head. After the credits the game returns you to the save before the two fights; there is no post-game.

Why can I not damage Pale?

He heals until all three floor switches in the room are weighed down. Push the rocks onto the bottom-left, top-left and top-right switches while ignoring the zombies, then he becomes a normal fight.

Which bosses change with alignment?

Two. At the Seal of Despise you fight Vicious on the good path and Vague on the evil path. At the Shrine of Shame you fight Virulent (good) or Lady Charity (evil). Pale, the Letter Carrier, Ghost of Ladon, Ladon and Osiris are fought on both paths.

What level should I be for Ghost of Ladon?

The 2010 community walkthrough recommends going in at level 42, 46 or 49, the levels where new armor sets unlock, with 60% Potion Extracts and several Origins of Life. Players who go earlier report fights that drag on for twenty minutes or more.
