Question: how do rerolls work in aram?
Answer: You gain Reroll points based on games played and champions owned. Once you've saved up 250 Reroll points, it grants you 1 Reroll, which is used to perform a Reroll in ARAM. You can only have 2 Rerolls saved up; When you have 2 Rerolls, you no cannot accrue Reroll points.
