Datapack on Titan

Transforming into a titan draws on a titan energy bar, and some items need more energy than others. The energy bar depends on how many vertebrae a player has, so transforming requires at least two or three. Titan shifters regenerate at a low constant rate and go on cooldown whenever they take damage. Titan punches cause area damage and can break a large group of blocks when striking the ground. After detransforming, a titan's inventory is stored at its nape, so items cannot be reached while in titan form.

Omni-Directional Aerial gear is paired with a breezebottle that draws its fuel from wind charges. Tapping sneak with the gear in one hand and the breezebottle in the other activates it. Six seconds of unassisted gliding cost one charge, and an aerial maneuver uses the entire charge at once, launching the player in the direction of the movement key. The Hardening update lets titans harden parts of their form, and a Change.Titan Sex trigger switches between masculine and feminine titan forms. Pure titan spawning is disabled by default and can be enabled with the titan-cheats/enable titanspawning function, and the Lordship and Royal Blood updates add further content.

The data pack needs a resource pack to be loaded, and the author publishes both together with a written summary and a showcase video. The mod is released under All rights reserved, so it is not open source.
