The Bouncing Bloom

Sporespring deals 2500 base toxin plus a 1250/s forced toxin DoT, multiplied by Strength; Brightbonnet adds 30% x Strength, doubled if you throw a Sporespring into it first.

Each of the 10 bounces multiplies damage by 1.5x and adds 25% crit chance.

While in Reroot (which counts as invisibility) Arcane Crepuscular's flat crit-damage add pushes the final bounce to red crits.

1.

Optional: cast Stinkbrains (tap 1) around the map for viral and sleep, or keep your subsume active instead.

2.

Cast a Brightbonnet (tap 2) under you and jump on it for energy and Strength.

3.

Cast Sporespring (tap 4) three times fast at the Brightbonnet.

4.

Enter Reroot to be immortal and unseen; wait for all bounces, then pop out and repeat.

Reroot is total invulnerability.

Between casts, shield gate off your constant ability casting (Augur mods or Brief Respite), and if you die you revive by touching one of your mushrooms, so always keep a Brightbonnet nearby.

Huras or Shade keeps you invisible so Reroot is a bonus rather than a crutch.

Duration only for the 1 and 2 mushrooms and Reroot; it does not touch Sporespring.

Efficiency negative because Brightbonnet pulses energy scaled by Strength.

Range is the priority, maxed, so Sporespring's zero-falloff explosions hit the whole room.

Strength is second, driving the nuke and the Brightbonnet boost.

Blind Rage, Transient Fortitude, Umbral Intensify are the Strength.

Overextended, Stretch, Augur Reach set the maxed Range, with Augur Reach also feeding the gate.

Primed Flow is the pool.

Archon Continuity is Duration plus corrosive procs off Sporespring's toxin.

Corrosive Projection helps the early bounces.

Precision Intensify over Umbral Intensify if not subsuming Roar.

The aura and exilus are open.

Pick one.

Subsume over 1 (mobile or endurance) or 3 (stationary).

- Roar for Sporespring damage and a toxin double-dip.

- Breach Surge for homing sparks off Sporespring's damage and toxin, double-dipped by Crepuscular.

Arcane Crepuscular for the flat crit-damage add in Reroot (this is what makes the final bounce red-crit), Molt Augmented for Strength.

Note Nourish, Camisado, Hotshot and Arachne do not affect Sporespring.

Madurai for Strength and cast speed.

Any works given the immortality.

None specific.

Spore-themed weapons (Coda Sporothrix, Sporelacer) for flavour and viral spread; a viral primer or Shade with Tazicor for the 10-stack multiplier.

Reroot immortality plus shield gating plus mushroom revive.

It fails only if you have no mushroom down when you die.

Brightbonnet pulses cover the 45% Efficiency cost.

Bosses (Sporespring targets centre mass and does not special-case them).

Very open tiles where enemies spread past even 280% Range's bounce reach.

The setup rhythm is unforgiving if you fumble the triple cast.

A Precision Intensify non-Roar build.

A health-tank build for sub-level-500.

Strong: enormous room-clear numbers, true immortality on tap, self-revive, squad energy from Brightbonnet.

Weak: boss-blind, setup- dependent, wants a primer for the ceiling, 5 forma.

Players who want a toxin nuke frame that literally cannot die while it waits for the room to melt.
