Epic Rolldown

The shop action that discards the visible champion shop and draws a new set, costing 2 gold by default. Augments and items frequently grant free rerolls or shop refreshes that key off this mechanic.

The player-side progression resource. Spending gold on XP buys it; each level raises the team-size cap and shifts shop odds toward higher-cost champions. Augments grant XP directly or trigger off "level up" to accelerate the curve.
