Spike is a B-tier uncommon slime in Slime RNG, available across every biome. Drop odds: Uncommon roll. Combat role: Fast attacker.
Aggressive, twitchy, and twice as fast as it looks. Spike is the best early Uncommon to keep until you get its Huge form.
Roll in any standard biome — Spike has no biome lock, every zone drops it
Drop rate scales with biome unlock depth — Cavern and Tundra hit it more often than Beginner Pond
Used as the primary Crafting Machine ingredient for Orca and several mid-tier recipes
Frequently included in event drop tables during early-game promotional weeks
Fast attacker. With 55 damage and 1.2 speed, best slotted in mid-game biomes — graduate to a higher-tier slime when farming endgame.
Available from any biome — roll wherever your current Luck stack is highest.
Duplicates fuel the Crafting Machine — see the Crafting page for recipes that use this tier. Always run the Trade Calculator before sealing a deal.
Trade value drifts with each patch — new slimes shift demand, codes shift supply. Cross-check against the live Tier List and the Trade Calculator before locking in any deal involving Spike.
Spike is the slime that decides your first 24 hours of Slime RNG. It's the Uncommon-tier breakout pull that takes you from 'Fin is fine I guess' to 'oh this game has teeth'. The 1.2 speed stat is the highest of any low-tier slime, and combined with 55 damage it carries cleanly through the entire Candy Land → Cavern transition. More importantly, Spike is the gateway to Huge Spike — the S-tier carry that anchors most endgame compositions — which means every Spike you pull is a potential 1-in-1,000,000 Huge re-roll candidate. Don't dismiss the pull just because the rarity tag says Uncommon.
The standard early-game composition. Run this through Candy Land and into Cavern's first hour. The moment your damage feels insufficient, that's your cue to push harder for Orca or stack luck for the Huge Spike chase.
When you decide to seriously chase Huge Spike, this is the composition. Run rolls in any standard biome with Apple + Ultra Luck Boost active. Two Lucky Slimes give you the best baseline luck stack you can build before unlocking Huge Lucky.
Spike trades in the 30M–80M Coin band — slightly cheaper than Fin despite higher rarity, because supply outpaces demand at the Uncommon tier. The interesting wrinkle is that Spike is one of the few slimes whose trade value goes up during major content patches (because new content typically increases demand for Crafting Machine inputs, which rely on Spike). Veterans rarely sell Spike outright; the Orca crafting recipe consumes 2 Spike per craft, and most players hold 6–10 in inventory at any time as crafting fuel.
Speed buffed from 1.0 to 1.2 to better differentiate from Fin's 1.0.
Added as primary ingredient for the Magma Slime and Frostbite recipes.
Launch — introduced as the B-tier Uncommon Spike, no biome lock.
Same tier or mutation pool — natural follow-up chases once you've locked in Spike.
The questions players ask about Spike most — answered with the live stats above.
Spike drops at Uncommon roll. The fastest path: roll in any standard biome — spike has no biome lock, every zone drops it. Stack Luck Boosts, Apples and an equipped Lucky Slime before opening rolls — see the step-by-step guide above.
Spike's base drop rate is Uncommon roll before luck multipliers. Active Luck Boosts, Apples, equipped Lucky Slimes and rebirth multipliers all stack to lower the effective denominator — use the Luck Calculator to see your real odds for the current pull.
Spike is currently rated "30M – 80M Coins" and fills the Fast attacker role in combat. Keep at least one for collection bonuses; duplicates can be traded or fed into the Crafting Machine for guaranteed mid-rares.
Spike can drop from any biome — there is no biome-locked spawn for this slime. See the Biomes page for the full unlock chain.
Spike sits at B-tier with uncommon rarity, 55 damage and 1.2 speed. See the full Slime RNG Tier List for how it ranks against every other slime in its bracket.
