Orbs are the most valuable currency in Fire Emblem Heroes. Resist the urge to spend them immediately on every new banner. Prioritize: Save Orbs for 'Legendary/Mythic Hero' banners, 'Hero Fest' banners, or banners featuring heroes you desperately need for your team (e.g., a specific skill for inheritance). Always summon a full circle of 5 units if you have 20 Orbs, as it's more cost-effective. If you're only targeting a specific color, only pull from those colored summoning stones. Set a budget and stick to it. Free-to-play be especially disciplined with their Orb spending.
