Poison Flask + Damage Tome
Poison scales off Damage multiplier. The wiki strongly advises Damage Tome over Precision Tome since poison does not crit. Size Tome is also a priority since the Plague passive's spread radius scales with Size.
4-8 min
Size Tome + Duration Tome
Size widens the poison explosion spread radius on enemy death. Duration makes each poison stack last longer, dealing more total damage before death and spreading more stacks to nearby enemies.
8-12 min
Moldy Cheese + Black Hole
Moldy Cheese poison spreads via the Plague passive per the wiki. Black Hole is wiki-confirmed as a strong Amog synergy since it scales with Size and Duration and holds enemies in place while poison ticks.
12+ min
Gas Mask + legendary items
Gas Mask gives Armor and Lifesteal per poisoned enemy. In long runs with many enemies poisoned simultaneously it provides significant survivability. Unlocked by killing 5,000 enemies as Amog.
This variant focuses on holding enemies in place while poison chains. Frostwalker and Black Hole are both wiki-confirmed Amog synergies. Ice Cube also holds enemies per the wiki. Duration Tome keeps freeze and poison durations high. More time enemies spend unable to move means more total poison damage before death and more spread triggers.

How to Play Amog in Megabonk
Do not take Precision Tome
The Amog wiki page explicitly states Precision Tome is strongly not recommended since poison does not scale with crits in any way. Damage Tome is the correct investment instead. This is one of the most specific and actionable pieces of advice on any character's wiki page.
Size and Duration are the key secondary stats
Size widens the Plague explosion radius when poisoned enemies die. Duration makes each poison stack last longer, dealing more total damage before death and spreading more stacks. Both are confirmed priorities on the Amog wiki page.
Moldy Cheese poison chains through the passive
The wiki explicitly confirms the Plague passive spreads all Poison including Poison applied by Moldy Cheese. Applying Moldy Cheese to a group effectively makes every enemy in the group a potential spread trigger. Take Moldy Cheese every run.
Hold enemies in place to maximise poison
The wiki names Black Hole and Frostwalker as strong Amog synergies because they hold enemies in place while poison ticks. Ice Cube and Lightning Orb are also named. More time enemies spend stationary means more poison stacks accumulate before they die and trigger the spread.
Best Items for Amog
All three items are Amog-specific. Moldy Cheese and Gas Mask are wiki-confirmed. Moldy Gloves appears in the Amog Pacifist wiki build.
Moldy Cheese
Wiki-confirmed: the Plague passive spreads all poison including Moldy Cheese poison. Every hit on any enemy is a potential chain trigger. Amog's passive makes Moldy Cheese more powerful on him than on any other character.
Gas Mask
Amog-specific item: wiki page confirms it combines with Poison Flask and Moldy Cheese and is unlocked by killing 5,000 enemies as Amog. Grants Armor and Lifesteal per poisoned enemy, providing survivability that scales with how many enemies are currently poisoned.
Moldy Gloves
Named in the Amog Pacifist wiki build alongside Moldy Cheese. Adds additional poison application on hits, increasing the number of enemies poisoned simultaneously and feeding the Plague chain more frequently.
How to Unlock Amog in Megabonk
Amog requires two separate unlock conditions: 50,000 poisoned enemies with Moldy Cheese and having Poison Flask unlocked.
1
Unlock Poison Flask
Kill the Scorpionussy Miniboss in the Desert 3 times. Any character can be used. Purchase Poison Flask from the Unlocks tab for 2 Silver.
2
Poison 50,000 enemies with Moldy Cheese
Carry Moldy Cheese in any run and poison enemies. Progress is cumulative across all runs. Any character works but Amog himself speeds progress once unlocked in part. Fox is recommended for better chest item odds when farming this.
3
Buy Amog from the Unlocks tab
Return to the Main Menu, open the Unlocks tab, and purchase Amog with Silver once both conditions are met.
How Good is Amog in Megabonk?
Amog is excellent against large groups of enemies. His Plague passive makes every poisoned enemy a chain trigger, meaning a well-placed Moldy Cheese or Poison Flask hit can clear entire clusters simultaneously. He starts with more Max HP and Armor than most characters, making him durable. His weakness is single-target damage against bosses since poison does not crit and Poison Flask is a DoT weapon. The wiki notes Amog can struggle against bosses with invulnerability phases.
