Mage Castle Idle Defense

Mage Castle Idle Defense is a castle defense game where a lone mage holds the line against endless enemy waves and hulking bosses. Each fight makes him stronger, opening up new spells while boosting core stats like attack, defense, speed, range, and health. Mixing abilities lets you answer tougher enemy types, while boss battles push you to use your full kit at the right moment. Seven locations wait ahead, with each new area opening after you finish the previous location's quest.

How to play?

Stop enemies before they reach the tower. Fallen foes drop coins, which you spend during the fight on battle upgrades. If you lose, those coin upgrades are wiped. Stronger enemies drop souls instead, and those pay for permanent upgrades between runs. Quests reward gems that unlock rune slots, and those bonuses stay with you after defeat. Socket runes, combine spells, and adjust your setup for different enemy types. Beat more waves than your last run to level up and earn spell scrolls. Save those scrolls for bosses, then burn through all of them when a boss shows up.
