Taproot Eruption

#Overview

Taproot Eruption is the evolution of Root Spikes. A chest can evolve it once Root Spikes is at max level and Tibo owns Masher Grip (see Evolutions). Every 1.5 seconds it picks 8 different pests within 150 units of Tibo, or 9 with Tibo's base +1 amount bonus. After 0.25 s a giant root erupts under each one, dealing 90 damage within 16 units (10 × 1.6 area) and throwing pests back with knockback 3 instead of Root Spikes' 1.

Compared with a max-level Root Spikes, it reaches almost twice as far (150 units instead of 80), roughly doubles the damage and fires about every 1.5 s instead of 2.2 s.

#How it works

• Targeting works the same way as Root Spikes. Each root picks a different random pest in range, and it only fires when a pest is within 150 units. If fewer pests are in range than roots, the extra roots are lost. Each root lands where its target was when it was picked.
• Knockback. Pests are pushed away from the centre of the eruption. The push strength is knockback × Tibo's knockback multiplier × (1 − the pest's mass) × 70, so heavy pests move less and bosses are never pushed. Masher Grip adds 25% knockback per level, so the catalyst keeps strengthening this weapon after the evolution.^[1]

Measured in the headless sim (tools/play.mjs, build 41 main-B2gf34bA.js, Standard, Normal, god mode, seeds s1, s2 and s3; the seeded starting weapon removed, the weapon given with give, spawning stopped after 4 s of play and the pests already on the field held at fixed spots with 10⁹ HP; 12 pests held on a ring 75 units from Tibo): every 1.5 s exactly 9 pests were hit on the same tick, each for 90. All three seeds gave the same figures.

#Tips

• The knockback scatters pests away from where the roots land. That buys time when you are surrounded, but it can also push pests out of reach of short-range weapons such as Root Cellar.

#Stats

Values are the raw numbers from the game's definitions, before Tibo's global stat multipliers, difficulty and time scaling. In play, Tibo's base stats add +1 amount to every weapon except aura, cone, nuke and ring weapons, and make every duration ×1.25 (see Stats). Field names in code are the game's internal names. Attack descriptions such as “Melee slash” are this wiki's summary of the internal attack kind.

Evolutions have no level-ups in the game data; they use these fixed raw values.

#Behaviour parameters

Raw parameters of the attack (behavior), copied from the game definition. What they do in play is explained under How it works above.

#Obtaining

• Get Root Spikes to level 8 while owning Masher Grip (any level), then open a chest. See Evolutions.
