Tier Tower

Progression is organized into sequences of tiers. The built-in sequence tier tower:main gives every player a starting point at tier 0, and additional sequences can be made and given to players with commands. Each sequence defines how many prestige points a player earns and how the prestige multiplier grows, and that multiplier changes the cost of future leveling.

Players gain points by dropping items into a Vortex, which accepts sacrifices and grants eminence. A player can jump down to a lower tier to sacrifice current eminence and prestige, speeding up later leveling. The Vortex is uncraftable by default, because server owners often want to restrict certain areas. The mod also adds several decorative blocks, and its Obelisk display can have its offset set on the top, bottom, sides, front and face.

Progression formulas are written in the sequence JSON using standard mathematical operators, parentheses and functions such as min, max, sqrt, log, exp, pow and abs. EMI integration shows which items are valid to sacrifice. The mod is released under the GNU Lesser General Public License v3.0 or later and is open source. It bundles fabric-permissions-api and requires Fabric API. Files exist for 1.20.1 only.
