Combat Logic adds ARPG-style mechanics on top of vanilla combat—without replacing it. Spend stamina on dodges and skills, raise combo rank (E→SSS) for damage and regeneration bonuses, and read everything from a compact top-right HUD.

Hostile mobs show localized names and current/max HP. A vertical action feed (up to four lines) replaces chat spam for combat feedback. Parry works against mobs and players (PvP), with a 3-second cooldown after each successful parry.

World owners can scale hostile HP. Each player can disable combo or stamina/actions independently. Uses Script API (beta) and custom commands.

HUD compatibility

Likely conflicts: other packs editing hud_screen.json → hud_content; scripts constantly driving title/subtitle.
Moderate: persistent actionbar bars, large right scoreboard.
Usually fine: chat-only, worldgen, texture packs.

Put Combat Logic RP above other HUD RPs; test with others disabled if layout breaks.
