Poison Builds in Batomon Showdown

Poison is the slow status in Batomon Showdown. Shock wants extra direct hits. Burn wants victories to snowball. Poison wants the shared HP bar to still be there at 20 seconds so the stack can work. Players who copy a Chemist lock and then buy burst dragons are fighting their own clock. This page is the Poison shop plan. General status math is on combat. Chemist’s card is on the trainer guide.

The engine

Chemist gives Toxic monsters +1 Poison, and that bonus grows whenever any monster on your side levels up. Merges feed the aura. A board that never completes a 3-copy recipe is playing with a tiny tick. Black Sludge is the item twin of Battery Pack: it gives current Toxic units +1 Poison. Green Stone can promote a Common into an Uncommon if you need a body that actually counts as Toxic.

Poison used to ignore Shield. That is dead. Current notes: Poison no longer ignores Shield, and status damage into Shield is reduced (15 percent in the August pass). Shield cores such as Craghorn berry walls will stall you. Either stack enough Poison that the reduced ticks still win, or pivot into the Berroon comp on their terms. Do not assume a May VOD is still legal. Patch notes own the number.

Sudden death at 30 seconds can finish a Poison fight you almost won, or steal one you were about to close. If every battle hits the ramp and you lose, you are short on either stack or shared HP — not “unlucky animations.” Fast Forward hides the lesson. Controls maps pause.

Poison line used for Master-rank wins

Shop plan

Days 1–4: take Chemist if the three trainers include it. Otherwise only force Poison if the shop is already Toxic-dense. Buy cheap Toxic copies. Spend Youngster rerolls on pairs, not on previewing Legendaries. Lock a missing third copy. Do not buy Battery Pack “for damage” on this line.

Days 5–7: every loss costs 3 lives. You need a recognizable Toxic cluster plus at least one merge so Chemist has grown. Events that hand a buffed bug or a multicast body can still help if they leave room for Poison; a Bug Collector Brawlmantis is not a Poison plan by itself. See events.

Days 8–10: freeze. Extra Black Sludge, extra level-ups (candies, merges), extra fight length (heals, shields that you apply to yourself). Sirenade stripping debuffs is an enemy of your stack if you somehow splashed Water. Stay on-message.

The embedded video is a Poison session aimed at Master-rank finishes. Copy the patience, not a six-unit screenshot from a different patch. Ranked still softens low-tier boards; a Master hose is not a Bronze shopping list. How to play explains the withhold and soften rules.

What not to mix

• Shock. Direct hits retrigger Shock; status ticks do not. A hybrid that never casts is a worse Shock build and a worse Poison board.
• Chef / Redhead Burn. Burn wants wins to permanently grow. Poison wants long losses that still tick. Pick one status for the run. The other engine is Burn builds.
• Mad Scientist day 7. Random level-1 Legendaries can delete your Toxic mesh. If you locked that trainer, read mythical builds instead of this page.

Formiqueen haste on Commons can still help Poison if the Commons are Toxic and adjacent. Onsetra repeating Ongoing is a Formiqueen story first. Do not buy the dragon unless the Ongoing unit is actually your tick source.

Lives and ranked

Poison runs often look “fine” at 8 lives and then die on two day-6 stalls against Shield. Budget with the 10-win guide. Overwriting a ranked save still scores wins minus 5. Test Chemist in Casual. Ranks.

Launch sets on September 15, 2026 may add more Toxic names. Until they exist, this is the Chemist-and-sludge plan. The items page lists Black Sludge, berries, and extra item uses that keep the engine fed.
