The ten-slot foundation
Body, Soul, Class, and Spec each provide one core ability slot. AGI, CHA, DEX, INT, STA, and STR each provide one stat ability slot. Every slot holds one equipped ability and can level up. Weapon and Flair add two gear slots to the displayed character sheet, not two more ability slots.
A slot is not every power you know
Class pool abilities are slot-free and unlock at their listed character-level gates. They still obey resource, target, activation, and selected-path requirements. Slottable abilities must be equipped separately. A shared pool-group name never grants another Class’s entire kit.
Two Innates, no extra slots
Body and Class each grant one free permanent Innate choice. These cannot be swapped, level with the character during a match, and cost no allocated points. They can remain private rather than appearing on public sheets.
Compatibility is more than a color match
Standard stat colors match their corresponding slots. White is passive-only. Clear accepts active or passive abilities. A dual-color slot accepts either listed color, not two abilities. Specific Body, Soul, Class, or path requirements remain in force even when the color matches.
Change your loadout, keep the distinction
The swapping model allows changes outside combat, such as on the Dance Track or at a pit stop, and lets a slot retain its upgrade level. Mode-specific rules govern the actual opportunity. Gear-granted powers and explicit bonus gear slots follow their own rules.
