Overview
| Item | Details |
|---|---|
| English Name | Sonic Bloom |
| Japanese Name | ソニック・ブルーム |

Effect and Behavior
Fires projectiles in the player's movement direction that grow larger as they travel. Each shot starts small and expands while in flight — by the time it reaches its range limit it covers a significantly wider area than it started with. Area-boost passives compound directly with the growth mechanic, making Candelabrador an exceptionally high-value pick. Level scaling increases projectile count, damage, and growth rate.
Unlocked by surviving 15 minutes with Brownie (Operation Guns DLC). Directional dependency means positioning is important — always move toward dense enemy clusters to maximize forward-facing coverage. The evolution material, Weapon Power-Up, also grants a Revival when acquired, making the progression toward evolution simultaneously a survivability investment.
Evolution Conditions
Max Sonic Bloom (Lv 8), carry Weapon Power-Up (an item that randomly levels one equipped weapon and grants Revival +1), and open an elite-drop chest after 10:00 to evolve into Wave Beam.
Wave Beam Effect
After evolution a charge mechanic activates when standing still: stopping builds a charge that releases a powerful auto-aimed blast significantly larger and stronger than normal projectiles. Moving fires the regular growing shots; standing briefly triggers the charge blast. Both modes remain usable, enabling flexible two-mode combat depending on the situation.
Strengths
- Growing forward projectile covers increasing area at range — area passives compound with the expansion
- Candelabrador synergy is exceptional — size bonuses amplify both the starting and ending size
- Weapon Power-Up grants Revival +1, making the evolution path also a safety investment
- Post-evolution two-mode combat (moving shots vs. standing charge) adds tactical flexibility
Weaknesses
- Requires the Operation Guns DLC
- Unlocked only by surviving 15 minutes with Brownie
- Directional dependency — rear and side enemies are difficult to hit without repositioning
- Standing to charge is risky when surrounded by enemies
Recommended Characters
- Brownie: the unlock character — natural starting fit
- Gennaro: extra projectile count adds shots per volley
- Imelda: +10% Growth speeds evolution
Recommended Passives
- Weapon Power-Up: mandatory for evolution; Revival bonus applies on pickup (top priority)
- Candelabrador: area expansion compounds with the growing projectile — highest-value passive for this weapon
- Spinach: +10% Might raises per-shot damage across all growth stages
- Duplicator: extra projectile count adds shots per firing cycle
Synergistic Arcanas
- IX Divine Bloodline: crit compounding with wide-area growing projectile coverage
- XX Silent Old Sanctuary: projectile +1 and speed bonus increase shot density
Strategy and Tips
- Early (0–10 min): Level Sonic Bloom and prioritize Candelabrador immediately — the area bonus transforms the weapon's effective coverage. Always face dense enemy clusters when firing.
- Mid (10–20 min): Collect Weapon Power-Up and evolve into Wave Beam. The Revival bonus from Weapon Power-Up applies on pickup, giving a safety margin during the leveling phase.
- Late (20+ min): Learn the charge timing — brief pauses during lulls between waves generate charge blasts that can delete elite enemies and bosses. Candelabrador stacking makes both shot modes cover massive areas.
FAQ
Q: How do I unlock Sonic Bloom?
A: Survive 15 minutes with Brownie. The Operation Guns DLC is required to access the character.
Q: Where does Weapon Power-Up drop?
A: From field pickups and level-up rewards. Each pickup immediately levels a random equipped weapon and grants Revival +1, so collecting multiple copies benefits the entire build, not just the evolution.
Q: When does the charge blast fire?
A: After evolving into Wave Beam, standing still builds a charge that automatically releases as a powerful auto-aimed blast. Charge does not build while moving — brief deliberate pauses trigger it.
