Oozy Codex — Codex Revelation
Oozy Codex is a progression-rich expansion for Tensura: Reincarnated on Minecraft 1.21.1. It transforms skill growth, analysis, research, awakening, attunement, and ascension into connected survival systems instead of command-only rewards.
What’s inside
- 248 native skills with structured Pursuits and command-free acquisition paths
- All 13 Slimey Legacy Ultimate Skills, integrated with save-compatible identities
- Insightful Elder, a tier between Sage and Great Sage with analysis and limited legal lower-tier skill copying
- A dedicated seven-tab Living Skill Registry for Skills, Pursuits, Bestiary research, Lore, Scripts, Mastery, and the World Language Tome
- Five native Ascension abilities with their own skill icons
- Fast Start for every race-selection path, with Insightful Elder and starter resistances—but never Predator
- Character Reset commands and items that correctly clear Fast Start and completed Pursuit state
