Polish has a Step Cost of 3, Duration of 8, and a Recharge of 7. It is a useful skill (buff) that adds quality every step when active, but cost 3 steps. This is useful for two 'Triggers': "half quality gain" (HQG) and "+7 chaos every skill"(7Sk). So, you can skip 3 steps and gain 7 chaos instead of 21, and also gain some quality later. For HQG, it limits the duration of the halving of your quality; this might be good if the next trigger is helpful or avoidable. Raising this skill reduces its cooldown, raises its duration, and improves the quality gains.
