Highest drop density at Glacier Peak; the lower-altitude tundra spawns less reliably
Boosted drop rate during winter events and December promotional weeks
Crafting Machine ingredient for the Frostbite Slime upgrade path

Ice Slime is Slime RNG's crowd-control specialist — a utility unit that punches well above its 10M trade-value tier in any composition that involves boss mechanics or DoT layering. Its 'damage' stat is officially listed as 'Utility' because it doesn't actually deal damage in the conventional sense; instead, its hit-box freezes enemies in place for a few seconds, opening windows for other slimes to land their full attack rotations. The Slime RNG community treats Ice Slime as the 'enabler' Common — the unit you don't appreciate until you try a Forge Sentinel or boss-rush event without one, and suddenly understand why veterans never delete it from their roster.
The standard build for any boss-rush event mode. Ice Slime locks the priority target while your DPS slime burns it down. Most event clear-time records use Ice Slime in this exact slot.
The combo that makes Fire Slime actually feel strong. Ice Slime's freeze window gives Fire Slime time to land its full DoT rotation; without the freeze, fast enemies die before the DoT ticks add up. Use this for Forge Sentinel and any high-HP elite farming.
Ice Slime trades in the 10M–35M Coin band — the lowest absolute floor of any utility-tier slime. The math is structural: Frozen Tundra access requires a level-22 wall that filters out new players (who would be the natural buyers), while veterans who have access farm enough Ice Slimes to cover their needs. Trade demand spikes briefly during boss-rush events (when CC suddenly becomes essential) and dips back during normal weeks. Most veterans hold 3–5 Ice Slimes permanently; they rarely list them for sale because the Frostbite crafting recipe consumes them.
Freeze duration adjusted from 2.5s to 3.0s to better support boss-rush event modes.
