Summons frogs that hop toward nearby enemies, dealing area damage on each landing. The frogs move semi-autonomously — they target nearby enemies but with some randomness in their jump paths, covering a wide area over time. Level scaling increases the number of frogs, their damage, and jump frequency; at high levels multiple frogs blanket the screen with constant landing impacts.

Unlocked by purchasing from the Librarian (the in-stage shop). Union evolution requires both Anura and Soul Eater at max level simultaneously — both occupy weapon slots and both must be maxed to evolve. Soul Eater grows stronger with each item collected (hearts, gems), meaning the Anura + Soul Eater combination naturally incentivizes aggressive pickup collection throughout the run.

Max both Anura and Soul Eater (Lv 8 each) and open an elite-drop chest after 10:00 to trigger the Dark Frogamorphosis union evolution. Both weapons are consumed into the single evolved weapon, freeing up one weapon slot after evolution.

Dark Frogamorphosis Effect

After evolution the weapon "may actually eat enemies" — the official description intentionally hedges with "may actually," maintaining the game's humor. In practice this refers to an instant-kill or massive-damage effect on enemies. Eating enemies can generate large amounts of experience and drops, creating a snowball effect in the late game.

• Frogs autonomously jump across a wide area providing solid area coverage without player aim
• Multiple frogs at high levels blanket the screen with landing impacts
• Post-evolution instant-kill eating effect handles large enemies and mini-bosses
• Synergizes with Soul Eater's item-collection scaling for a coordinated pickup-focused build

• Union evolution requires two weapon slots for the pre-evolution setup
• Both Anura and Soul Eater must reach max level — a meaningful time investment
• Frog jump landing is semi-random, making it hard to focus on a single priority target
• Requires purchasing from the Librarian (gold cost) for initial unlock

• Characters with item-collection bonuses: amplify Soul Eater's scaling, boosting the overall union's power
• Imelda: +10% Growth speeds both weapons to max level faster
• Poppea: item attraction bonus increases pickup collection rate, fueling Soul Eater

• Spinach: +10% Might raises frog landing damage (top priority)
• Candelabrador: wider area expands frog jump landing radius, increasing area control
• Clover: improved drop rates increase item collection volume, accelerating Soul Eater scaling
• Hollow Heart: HP boost for survivability during the dual-weapon pre-evolution setup

• IX Divine Bloodline: crit compounding with multiple frog landing hits
• XXI Game Killer: increased item spawns accelerate Soul Eater's collection-based growth

• Early (0–10 min): Level both Anura and Soul Eater simultaneously. Collect every heart and gem to drive Soul Eater's power scaling. Frog coverage expands naturally as both weapons level up.
• Mid (10–20 min): Both at max level → union evolve into Dark Frogamorphosis. The eating effect immediately becomes relevant against larger enemies and mini-bosses.
• Late (20+ min): Dark Frogamorphosis eating and area coverage combine to handle dense waves efficiently. Stack Clover to maximize drop collection and extend the snowball effect from enemy eating.

Q: How do I unlock Anura?
A: Purchase it from the Librarian (the in-stage shop). Gold is required.

Q: How is a union evolution different from a standard evolution?
A: Union evolution requires two weapon slots — both Anura and Soul Eater must be at max level. No passive item is required. After evolving, both weapons merge into Dark Frogamorphosis, freeing up one weapon slot.

Q: What does "may actually eat enemies" mean for Dark Frogamorphosis?
A: The official description is deliberately vague as part of the game's humor, but the effect is an instant-kill or massive-damage hit on enemies. Eating enemies can generate large experience and drop rewards, enabling a strong late-game snowball.
