Alacrity is a power cartridge drawn when your pet levels up during a run. When chosen, each obelisk or monolith your pet activates for the rest of the run adds a 1% boost to attack speed and agility, up to a cap. Effect and cap scale with cartridge level. Multiple cartridges stack the bonus additively, but the cap does not stack.
