A-tier passive Shroom applicator. Whenever Fulbert receives Spice or Shell — from any source, any amount — he automatically applies the same amount of Shroom to a random enemy. Pyra's Spice 4 on Fulbert = Shroom 4 on a random enemy. Kernel's Shell 2 to the ally behind = if Fulbert is behind Kernel, Shroom 2 on a random enemy. The passive conversion requires no Counter activation, no timing — Fulbert just needs to be in position to receive the buffs.

The "random enemy" targeting is his main limitation in multi-enemy fights. In single-target boss encounters, the Shroom always lands on the boss, making Fulbert extremely efficient there. In wave fights, Shroom spreads, which is still useful (Shroom damages on enemy counter activations) but diluted compared to focused application.

Place Fulbert where buff-giving allies can reach him. Behind Kernel: Kernel's Shield 2 on hit flows to Fulbert as Shroom 2 on an enemy. In Pyra's buff range: Pyra's Spice 4 Reaction on Fulbert generates Shroom 4 on a random enemy each trigger. Fulbert does not need to be the primary target of these buffs — as long as he's in the path of Spice or Shell distribution, his conversion fires.

Counter 3 and 1 Attack make him a moderate attacker, not a carry. His damage output from direct attacks is low. His value is entirely the passive Shroom conversion. Positioning him in a high-buff-income spot is more important than any charm investment except Attack (to improve his direct kill-securing ability).

Fungun amplifies Fulbert's contribution. Each Shroom Fulbert applies adds to Fungun's trigger threshold, and each Fungun activation adds more Shroom. The two cards together accelerate Shroom accumulation faster than either alone.

Pyra → Fulbert Spice 4 chain. Position Pyra directly in front of Fulbert. Each time Pyra's Reaction fires and applies Spice 4 to Fulbert, Fulbert simultaneously applies Shroom 4 to a random enemy. In a fight where Pyra fires 3 times, that's 12 total Shroom applied to enemies passively — without any item spend.

Kernel + Fulbert in the same column. Kernel in the front row, Fulbert one row behind. Every time an enemy hits Kernel, Kernel distributes Shell 2 to the ally behind — Fulbert. Each Shell distribution triggers Fulbert's conversion: Shroom 2 on a random enemy. High-frequency enemy attackers make this extremely efficient.

Shelly kill-reward chains into Fulbert. When any ally kills an enemy, Shelly applies Shell 3 to the killer. If the killer is also in position to pass buffs to Fulbert (or if Fulbert is the killer), the Shell 3 triggers Fulbert's Shroom 3 conversion on a random enemy per kill.

• Pyra — Spice 4 Reaction on Fulbert = Shroom 4 on random enemy; high-frequency Spice source is Fulbert's best partner
• Kernel — Shell 2 per Kernel-hit converts to Shroom 2 on random enemy; passive and consistent
• Fungun — each Shroom Fulbert applies feeds Fungun's thresholds; combined Shroom pressure accelerates
• Shelly — kill-Shell 3 on the killer triggers Shroom 3 via Fulbert if Fulbert receives the buff
• Attack charms — modest Attack upgrade lets Fulbert secure kills more often, which enables more positioning flexibility

When Spice'd or Shell'd, apply equal Shroom to a random enemy
