What is the best way to spend my gems in Royal Kingdom?

For efficient gem use: - Prioritize **hero upgrades**. - Purchase **resource packs** during sales. - Save for **special events** where gem spending offers higher returns.

Gems, glorious gems! I suggest using them for **expansion slots** and **premium heroes**. This gives you more flexibility in your gameplay.

If you want to maximize gem value, consider using them for **energy refills** during major battles or events. Always aim for long-term benefits.
