Root Spikes

#Overview

Root Spikes makes roots burst up under pests near Tibo. Every 2.8 seconds it picks 3 different pests within 80 units of Tibo, or 4 with Tibo's base +1 amount bonus (see Stats). It marks the spot under each one, and 0.3 s later a root erupts there. The root deals 22 damage to everything within 10 units and knocks them back.

You get it from a level-up card. At level 8 it targets 9 pests (8 + 1) for 44 damage every 2.2 s, with a 12-unit blast (area 1.2). With a max-level Root Spikes and Masher Grip, a chest can evolve it into Taproot Eruption.

#How it works

• Targeting. It only fires when at least one pest is within range (80 units) of Tibo. Area bonuses do not increase this range. Each spike in a volley picks a different random pest in range. When there are fewer pests in range than spikes, the extra spikes are lost.^[1]
• Delay. The spike lands where the pest was when it was targeted, delay (0.3 s) later. A fast pest can walk out of the 10-unit blast before it erupts. Any other pest standing on the spot is hit as well.
• Each blast's radius is size × area. Amount bonuses from GPU and Sprouting Eyes add more spikes per volley.

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 60 units from Tibo): at level 1 every 2.8 s exactly 4 pests were hit on the same tick; at level 8 exactly 9, every 2.2 s. All three seeds gave the same figures.

#Tips

• Extra spikes are only useful when enough pests are close to Tibo. It does nothing against pests that are far away.
• The blasts are small, so slower pests that walk in a straight line are the easiest to hit.

#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.

#Level progression

Each level-up adds the listed change to the weapon's raw values. Totals are cumulative.
