Overview
Celestia SMP's modpack includes the Aspects mod, which is an addon to the Origins mod. It aims to contribute to Minecraft's combat system, and adds features that are a bit more unique than the regular Origins that are out there, with types falling under the aspects. Each aspect has two types to choose from after the initial aspect selection.
On the official Celestia SMP server, players get one free origin switch (if they approach an admin), an origin switch also allows you to switch your aspects.
