Reroll
Rerolling swaps all three shop offers for a fresh set. It costs gold, and the price climbs each time in the same shop. You can also trade a charm you are carrying for rerolls instead.
In detail
The first reroll in a shop costs 25 gold and every one after it costs 25 more, so a realm's shop discount and any free rerolls it grants both shift where that climb starts. Selling a charm from your carry strip pays rerolls by rarity: a Common is worth 1, a Rare 2, an Epic 3. Cursed charms cannot be traded at all, and neither can your last remaining charm, so a sale can never leave you carrying nothing. A reroll bought with a charm is free to spend and does not push the gold price up, but it belongs to that shop: walk out with credits unspent and they are gone, along with the charm you paid for them.
