| Item | Details |
|---|---|
| English Name | Lump of Coal |
| Rarity | Common |
| Price | 2G |
| Type | Gem (special gem) |
| Class | Neutral |
| Size | 1 slot |
| Activation | On weapon socket (on-hit probability) |
| Overall Tier | B+ (A+ on Pyromancer) |
Effect
- Weapon socket: 70% chance on hit to deal +1 damage
- Backpack / armor socket: not supported (weapon-only)
- No same-type rarity upgrade (different spec from regular gems)
Regular gems change effect by socket location and upgrade through Chipped → Flawed → Regular → Flawless → Perfect. Lump of Coal is an independent special gem holding only a weapon-socket damage +1 effect. Simple design, but the 70% high proc rate and cheap price give it very high early-game versatility.
Evaluation & Analysis
Lump of Coal is a special gem granting a permanent +1 damage on weapons for 2G — stable early-game damage booster providing consistent value across every class. The 70% proc rate rivals even some regular gem effects, and on high-attack-count weapons it delivers 50-150 cumulative net damage per match.
For Pyromancer construction, the rating climbs a full grade. Wooden Sword + Lump of Coal crafts Torch, a Heat-granting weapon that becomes the core of fire builds. Adding Flame craft further produces Burning Coal (Lump of Coal + Flame), an upgraded gem with Heat grant added.
