Glossary of Key Terms
Early Access patch notes and creator videos use shorthand. Use this glossary so Fate Dice, fusion patrons, Monster Cards, and Codex tracking stay clear while you climb Unfair+ Endless.
| Term | Definition | Related |
|---|---|---|
| Fate Dice | Re-roll currency for upgrade-card brackets. Default pool raised to 5 in 0.1.7.4. Also powers Constellation Ban (costs 3). | Relics, Fusion, Constellation Ban |
| Bracket | The numeric range shown on an upgrade card. Fate Dice re-roll the bracket so you can chase higher rolls or fusion offers. | Fate Dice, Fusion |
| Fusion Evolution | Hidden high-impact upgrade: base spell at level 10 + matching secondary patron must appear as a level-up choice. Not guaranteed — hoard re-rolls. | Spells, Codex, Fate Dice |
| Secondary Patron | Extra constellation / elemental god required for secret fusions (community tables often list Aquarius, Ursa Major, Sagittarius alongside the seven primary patrons). | Fusion, Constellations |
| Shatter | Bonus damage when fire effects break chilled / frozen enemies. Core of Fire & Ice hybrid builds with Absolute Zero. | Builds, Frost Nova |
| Hub Codex | Collection tracker added in 0.1.8.0. Each spell/evolution unlocks the first time you pick that upgrade. Cards show Codex entries as of 0.1.8.7. | Spells, Relics |
| Constellation Ban | Spend 3 Fate Dice to ban a constellation you own no spells from, shaping future upgrade offers toward your path. | Fate Dice, Endless |
| Monster Cards | After Endless floors, pick enemy buffs. Monster Health is always one of the two offered stats after the 0.1.8.7 rework. | Endless Mode |
| Cat Coins | Meta currency spent at the fox Relic Merchant for permanent relics. Distinct from the mid-run Cat Merchant consumables. | Relics |
| Relic Weight | How strongly relics appear / matter in your meta loadout. Achievements raise weight; capacity rises with infinite leveling. | Relics |
| Lifesteal | Kill-triggered regen that only activates when the Lifesteal relic is equipped. Elite kills heal more; values tuned in 0.1.8.1. | Relics, Endless |
| Skill Opacity | VFX clarity setting (Options or I / O keys). Lower opacity keeps dense Gemini / Leo screens readable and often smoother. | Tips, Performance |
| Incremental | Scalable difficulty after Unfair+ (+1, +2…). Each +1 uses the full Unfair→Unfair+ stat jump (0.1.8.3). Valid Endless starting tier. | Endless, Difficulty |
| Purification Well | Trial added in 0.1.8.3 — kill near the well to convert souls into XP. Rewards dense AoE (Leo / Gemini). | Trials, World |
| DPS Meter | Toggleable live damage meter in settings (0.1.8.8). Use it to cut dead-weight spells; a post-round breakdown is planned later. | Tips, Updates |
How to Use These Terms In-Run
You do not need every term on your first demo clear — learn them in this order as difficulty rises.
Learn the currency first
Cat Coins buy permanent relics. Fate Dice re-roll brackets and fund Constellation Ban. Mixing the two mid-run merchants wastes time.
Track fusions in the Codex
Level one spell to 10, keep the matching secondary patron available, then spend Fate Dice when the fusion option refuses to show.
Plan Endless around Monster Health
Monster Health is always on Endless cards after 0.1.8.7. Equip Lifesteal before deep Incremental floors.
Keep the screen readable
Skill Opacity (I / O) and the 0.1.8.8 DPS meter turn jargon into decisions — cut dead spells, keep pierce / chain that actually carries.
