RoGhoul Beat Koutarou Amon in Ro-Ghoul

Koutarou Amon is the midgame boss most Ro-Ghoul players hunt once they leave early Park Fighter loops. Community spawn data places him on a 5-minute respawn, behind a level 750+ gate, with lump RC, Yen, reputation, and XP that fund Kagune Stages or Quinque Lab far faster than trash NPC triangles alone.

This page expands the overview on Bosses with Amon-specific locations, rewards, phase notes, and farm hygiene. Promo string AmonBossIsBack! celebrated his return campaigns but is expired as of August 2026 — redeem live bundles on the Codes Hub instead of hunting that name.

Requirements before you fight Amon

Check	Detail
Level	750+ — below the gate you deal no meaningful damage
Focus	Caps from Focus Builds — Speed 200 / Physical 100 first
Weapon investment	Core Kagune or Quinque damage skill upgraded via Leveling
Movement	Dash and block drilled per Controls
Codes	Active RC/Yen codes redeemed — not expired event strings

Arrive under-geared and you become free XP for the boss while the group carries. Farm Touka / Nishiki bosses first if you are still climbing — see the spawn table on Bosses.

Spawn locations and timer

Amon uses open-world multi-spawn points rather than a single instanced teleport for the classic fight. Reported locations (cross-check Map & Locations landmarks):

• Mister’s Warehouse parking lot
• Near the Kakuhou Surgeon
• Cargo Yard
• Park near Mister’s Warehouse
• Parking lots near Anteiku

Respawn: about 5 minutes after a kill. Collecting the boss corpse often helps cooldown hygiene on Ro-Ghoul boss loops — do not leave remains if your farm route depends on fast respawns.

Only one Amon instance of his tier should exist at a time under the multi-tier boss system (low / mid / high tiers can overlap with different bosses). If chat says “Amon up” in another district, rotate instead of camping an empty lot.

Rewards worth the route

Community-reported clear rewards for Amon-class kills include roughly:

• 12,500+ EXP (some trackers list higher mid-2026 figures — expect patch variance)
• 500,000 Yen
• 5,000 Reputation
• 125,000 RC Cells

You typically need to contribute meaningful damage (often cited around a 5% HP participation floor on boss rewards) to qualify. Tag the boss early, stay alive through the phase change, and avoid AFK leech reports.

Spend RC immediately into your main damage line so the next spawn feels shorter. Yen banks toward lab unlocks or masks after combat stats are healthy.

Phase change at 50% HP

When Amon falls to about half health, he changes modes. Community notes:

• Moveset shifts — expect new timings on dashable attacks
• Damage output can drop after the swap even as patterns change
• Occasional glitches skip the mode change entirely; play the animation you see, not the wiki memory

Caller habit: one player announces “50” in chat or voice so DPS stops wasting skills into transition frames. Peel players watch adds if the public fight draws other bosses or PvPers.

Open-world PvP risk while camping

Amon spawns sit in contested Tokyo lots. Ghouls and CCG alike third-party farms. Mitigations:

• Bring a duo or trio from Discord LFG (Discord guide)
• Finish the kill quickly — long kiting advertises free RC
• Know escape routes toward Anteiku or CCG Tower using the map guide
• After farming, practice fair fights in Matchmaking instead of staging grief wars on the spawn

Private servers may alter some boss availability — Gyakusatsu famously does not work in privates; confirm Amon behavior in your VIP server before scheduling a long session.

Efficient Amon farm loop

1. Redeem active codes on Codes Hub (IwaSpec / anniversary bundles).
2. Hit level 750+ via Leveling and mid bosses.
3. Learn parking-lot landmarks from Map & Locations.
4. Clear Amon → loot → corpse hygiene → rotate secondary mid bosses during the 5-minute wait.
5. Dump RC into stages or lab → repeat.
6. When inventory fills with duplicates, vendor Yen — infinite slots from the Kuzen update make holding extras easier.

Pair with Farming RC & Yen on off-spawns so you never stand idle in an empty lot.

Build notes for the fight

Ghoul: High Kagune Focus after caps; rinkaku / aggressive lines burst phase windows. See Ghoul Build.

CCG: Quinque damage plus enough Durability to survive mode-change swings. CCG Build and Quinque Tier List help pick a farm weapon.

Glass cannons clear faster but die to third parties — balanced spreads win public-lot consistency.

Amon is the checkpoint where Ro-Ghoul stops feeling like a mobile auto-tapper and starts feeling like a route-based ARPG. Hit the level gate, learn two parking lots, respect the 50% swap, and turn every five-minute respawn into banked RC.
