Evolutionary Defense Tower

A tower builder item creates a Hell Tower, which comes online after its spawn animation ends. It starts hunting automatically, and it is bound to whoever built it, so it never targets its owner. Towers persist in the world, and a collector module lets a player pick one up, with its data carried back to a builder item for travel.

Evolution works through three tiers of attribute modules that customize the tower's defensive core. Nine evolution modules cover offense, defense, utility and a tower-exclusive form, and each module upgrades in a chain where tier N leads to the N+1 template. Right-clicking the tower's socket opens a hovered tooltip that shows what each module does. Two towers with separate combat identities are included, with a laser that attacks in an exponential combo and a multi-tier projectile launcher.

Installation needs Forge or NeoForge. The server and every player need the mod installed. Builds cover 1.20 – 1.21.1, with 1.3.0 as the latest file for Forge on 1.20.1 and NeoForge on 1.21.1, under the MIT License, which is not open source.
