Origins: Analgin Monster

Taking damage adds a fixed amount of Pain per hit, and a stronger hit adds more, up to a maximum of 100. Pain drains only when it is spent, and it can be refilled only by taking damage or by using special items the mod implements. Passive abilities convert a portion of incoming damage into Pain, and Pain regeneration spends 5 Pain at a time to restore one heart whenever health is full and Pain is at least 30. Dropping to 0 Pain starts withdrawal, which takes a heart every second until new Pain arrives, while reaching 100 applies poison and weakness until Pain falls below 100.

The race requires the player to balance accumulating Pain against spending it, because both extremes carry consequences. Its active abilities are bound to keys: Heal Pulse (G, 30 Pain) heals players within 10 blocks by 5 hearts, Pill Form (V, 20 Pain) makes the player tiny with complete invulnerability for 5 seconds, and Pain Boost (B, 40 Pain) grants a short burst of strength and speed. Analgin Monster requires Origins and Pehkui, and it runs on client and server under the MIT License. Its files target 1.20.1 only, for Fabric and Forge.
