Actions
| Action | Base Rate | Effect |
|---|---|---|
| Coinify | 70% | Item → 5× vendor sell price in Coin |
| Decompose | 60% | Item + gold → crafting materials or essence |
| Transmute | Varies by item | Item + gold → pool item; fail destroys item |
Failure: item destroyed, 10% base XP. Success: full XP + outputs. Catalysts consumed only on success.
Catalysts
| Catalyst | Bonus | Use |
|---|---|---|
| Catalyst Of Coinification | ×1.15 | Coinify |
| Catalyst Of Decomposition | ×1.15 | Decompose |
| Catalyst Of Transmutation | ×1.15 | Transmute |
| Prime Catalyst | ×1.25 | Any |
Teas (success / throughput)
| Tea | Effect |
|---|---|
| Catalytic Tea | +5% Alchemy Success (multiplicative on rate) |
| Efficiency Tea | +10% Efficiency |
| Alchemy / Super / Ultra Alchemy Tea | +Alchemy levels (+Efficiency); success only if below item level |
Success Rate
R0 = Base × CatalystMult × LevelFactor
s = R0 × (1 + AlchemySuccess)
LevelFactor = 1 + (0.9/ItemLevel)×(AlchemyLevel - ItemLevel) if Alchemy < ItemLevel
= 1 if Alchemy ≥ ItemLevelOver-leveling does not raise success (feeds Efficiency instead).
Transmute base rates vary by item/type (gems often ~55% category approx.; per-item differs — use in-game).
Laboratory
House room. Each level: +1.5% Eff, +0.05% Wisdom, +0.2% Rare Find.
Formulas
Base time: 20s. ActionTime = 20 / (1 + ActionSpeed). Speed: Alembics +15% to +105% base. Community buff.
XP: Base = Multiplier × (10 + item_level), Coinify ×1.0, Decompose ×1.4, Transmute ×1.6; fail 10% base XP.
Gear: Alchemist’s Top (+10% Eff), Alchemist’s Bottoms (+10% Eff), Enchanted Gloves (+10% Eff). Celestial Alembic (+4% XP, +15% Rare Find).
