Arbitrary Amplifier is a Special in Bconomy. It temporarily boosts an Action chosen by the player for others sharing their profile mode.

Main and Ironman profiles have separate shared effects. Hardcore profiles receive no shared effects, but their self-only copies affect their owner alone.

The Special was added to the game in Game Update (11-25-2024).

History

Before game update v2026.07.30 on July 30, 2026, Main and Ironman players shared the same global effects.

Changelog

Release date	Update	Changes
September 16, 2026	v2026.09.16	Broadcast history and “Show Old Broadcasts”. (TheCarriedOne) Broadcasts (boss fights, ascensions, relay milestones, special finds, menagerie and museum completions) are stored in chat history again. There’s a new setting under Gameplay → Show Broadcasts called “Show Old Broadcasts“. That setting is off by default so chat won’t open filled with older broadcasts; turn it on if you want broadcasts from before you loaded the game to stay visible after a reload or reconnect.
September 8, 2026	v2026.09.08	Announcements behavior. (Wewert) Progression and boss announcements show live but won’t stick in chat after you reconnect or reload. Repeated ascension, Museum collection, and Menagerie milestone announcements replace the latest matching entry while you remain connected. Discord keeps only the latest announcement in each ephemeral category: ascensions, collection milestones, rare and special finds, solo Ball Pit rolls, and each shared Ball Pit pool warning. Relay and boss event announcements still go to the Discord Events channel unchanged.
September 2, 2026	v2026.09.02	Bulk amplifier sets. (TheCarriedOne) A bulk set’s Use button greys out if you own none of the boosts. The Use button shows a countdown when the amplifiers in the set are on cooldown. On hardcore profiles the button now respects amplifier cooldowns. Calibrated Amplifier rows in the set editor no longer offer a 2x option.
August 17, 2026	v2026.08.17.2	Pinned Amplifiers and Pulsators fix. (TheCarriedOne) On hardcore and seasonal profiles, Amplifiers and Pulsators you own now appear under the pinned category consistently.
August 16, 2026	v2026.08.16	Amplifiers consumed in bulk sets. (TheCarriedOne) Amplifiers used through a bulk set are now properly consumed from your account. Previously they were not removed and could be reused indefinitely.
August 10, 2026	v2026.08.10	Obscure Sigil interaction on Hardcore. (TheCarriedOne) Obscure Sigil no longer extends the duration of self-only Calibrated/Arbitrary Amplifier boosts on hardcore profiles.
August 7, 2026	v2026.08.07.3	Bulk boost sets. (TheCarriedOne) Save named groups of boosts (either boost items or amplifiers) and use the whole set with one click from the Items sidebar. Each set has its own emoji and name; boosts inside are sorted automatically by tier and action. Manage sets in the item-categories modal. Editor has a Copy button that gives the chat command for the set so you can bind it to a hotkey. Using a set consumes everything at once. Amplifiers that are capped or on cooldown are skipped and you’ll be shown a report; if anything in the set is on cooldown you’ll be asked to confirm first. To be clear: you configure the bulk sets at the very bottom of Items -> Categories modal. Add items or specials (only one per section, can’t mix both) and save. You will see your bulk boosts in sidebar then, which you can toggle visibility on/off using the same bullseye icon that you already had before.
August 3, 2026	v2026.08.03	Leaderboard reset notification and reward fixes. (TheCarriedOne) Duplicate “Trophy earned!” notifications have been fixed. Ghost “Special” rewards are fixed so the Specials count matches what you actually receive. Both trophy notifications and item rewards are no longer sent if the reset fails. Leaderboard resets complete much faster and (should?) no longer trigger errors.
August 2, 2026	v2026.08.02	Work action multiplier display. (TheCarriedOne) Active amplifiers or item work boosts now show as a “🚀 N.NN× from Boosts” line in both the action button’s multiplier tooltip and the console “Multipliers:” breakdown.
July 30, 2026	v2026.07.30	Mode-specific boosts. (TheCarriedOne) Ironman global boosts (pulsator / amplifiers) now only affect ironman players, and main boosts only affect main players, they no longer boost each other. Special Store visibility. (TheCarriedOne) Hardcore and seasonal profiles no longer see the Noetic Pulsator or Arbitrary Amplifier in the Special Store since they can’t use them. Cleaner item names. (TheCarriedOne) The “(Self only)” tag has been removed from self-only amplifier/pulsator names.
July 29, 2026	v2026.07.29.3	Inventory discovery for self-only amplifiers and Pulsators. (TheCarriedOne) Self-only Calibrated Amplifiers, Arbitrary Amplifiers, and Noetic Pulsators can now be found and added to inventory categories without causing errors.
July 11, 2026	v2026.07.11	Buy specials from modal. (TheCarriedOne) You can buy purchasable specials directly from that special’s own modal. The special Buy input now supports buying multiple at once.
July 10, 2026	v2026.07.10	UI fixes. (TheCarriedOne) Chat send button no longer jumps in width while on cooldown; if you try to send too early a chat badge shows instead of error modal. Arbitrary Amplifier action picker buttons stop resizing as cooldowns tick down. On mobile, a slight sideways drift while scrolling no longer pops the sidebar open.
July 9, 2026	v2026.07.09	Special usable on work. (TheCarriedOne) The Arbitrary Amplifier special can be used on Work again.
July 8, 2026	v2026.07.08	Custom item categories. (TheCarriedOne) Create your own item categories: give them a name, emoji, set items and order. Pinned items become the reserved “Pinned” category. You may or may not continue using it. Reorder and hide any Items section (built-in ones too). Museum, Specials, and My Listings are now reorderable and sortable too. Sidebar quick-items: pick which categories appear there. Search now filters inside the categorized view (it no longer drops you to a flat list), auto-expands any collapsed sections the search matches, and has a clear button. Duplicate Relay Network section is now removed. Specials can be added to any category, any position. Pick a specific special (e.g. Calibrated Amplifier for Fish) or use (Any) to add all variants at once. The old per-device “pinned specials” list is replaced by category membership, so you’ll need to re-add any specials you had pinned.
July 7, 2026	v2026.07.07	Use modal and amplifier/modifier errors. (TheCarriedOne) Using an Arbitrary Amplifier or Forbidden Modifier repeatedly from the same open modal no longer fails on the second use.
June 14, 2026	v2026.06.14	Toasts now render Discord emojis correctly. (TheCarriedOne) Rare item and special item found toast notifications now show the item/special emoji instead of raw <:name:id> text. Much prettier!
May 5, 2026	v2026.05.05	Specials management UX overhaul. (TheDepartedOne) The Use button for Calibrated Amplifiers (and similar Specials) now respects the real server cooldown – it stays disabled for the full cooldown even after the boost effect ends, so what you see matches what the server enforces. Countdowns and “Expires in…” labels now respect clock skew between your client and the server, so timers won’t jump or disagree if your clock is a bit off. Inventory grouping: in the Specials section you can toggle Group (defaults on). When grouped, multiple variants of the same Special collapse into one row showing total count and the nearest expiry. Click the “N types” / secondary button to view all variants. Type-group modal: clicking a grouped row (or using certain text commands) opens a modal showing every variant of that Special type so you can pick which exact copy to use. New text command: you can now use Specials by type name with /special/use <type> [action]. Examples: If you call /special/use with no args you get a clickable list in chat that fills your chat box when clicked – handy! Arbitrary Amplifier picker now disables action buttons when that action already has the server-side max active boosts, and shows a countdown to the nearest expiry so you know when you can add another.
