Aviarab — the Multicast Engine Batomon Showdown Officially Confirmed in 1.3.0

What did the official patch notes say about Aviarab?

Before October 6, 2026, Aviarab existed only in community accounts — threads about huge Multicast stacks and a trainer-board line about Jinto flying builds. Patch 1.3.0 then mentioned it twice in one patch, which is the whole official record:

Two entries, one patch, and the ability’s core rules are on the record — which is why this page publishes while most community-only monsters on this site stay drafts.

What the community adds — labeled

The community side of Aviarab is older than the official record and consistent across threads:

• The stack math: “each copy is +1 multiattack” — players in the “x15+ multicast” thread treat extra copies as additive stacks, and chain “Gemwing + Aviarab to give the gemwing multicast” into the game’s biggest totals. Community-sourced, unverified.
• The Shiny difference: “buffs the whole shop instead of just next bought” — a behavior difference reported in a September build thread, and unconfirmed by any patch note so far. The same thread pattern is why Shiny variants are treated as mechanically distinct on this site.
• The trainer fits: the September trainer board’s Bug Catcher read — “stronger in Jinto (due to Aviarab + Gemwing into a good flyer like a Cawnushi/Quillustrous)” — and its Monster Ranger warning, “it can mess up certain Batomons completely (like Aviarab…)”, both live on the trainer tier list with their labels.

One more community-adjacent fact has real consequences: because the arm waits for a Flying Batomon, a non-flying build that buys Aviarab banks nothing until a flyer appears — which is exactly the situation the Zephyrex bugfix cleaned up. The Jinto region guide covers why these flying chains live in that pool.

What is still unknown

• Aviarab’s cost at each level, attack, health and full ability text — the patch entries give the Cost move and the arming rule, not the card.
• Whether the community’s “+1 per copy” and Shiny shop-wide behaviors match the live game — unverified.
• How the arm interacts with more than one Aviarab, or with Multicast from other sources (Clawnetic’s own ability, the Brawlmantis event reward) — no source on record covers the stacking.

The monster list files Aviarab under the Jinto pool, the best teams overview tracks the multicast archetype the 1.3.0 tax aimed at, and the Zephyrex page carries the other half of the same bugfix.
