Between waves, you'll enter the shop. Here, you can spend your accumulated gold on new weapons, items, and rerolls. Weapons come in different tiers (Common, Uncommon, Rare, Epic, Legendary) and offer varying damage and effects. Items provide passive bonuses to your stats or unique abilities. You can also reroll the shop's inventory for a small gold cost if you don't like the current selection. Be strategic with your purchases; sometimes saving gold for a powerful legendary item is better than buying several weaker ones. Consider your character's strengths and weaknesses when making shop decisions.
