Arcane Bastion is a fantasy tower defense game. Your castle stands at the center of the battlefield, attacks enemies automatically, and grows stronger with every upgrade. Eight defense positions surround it. Build ballistae, evolve them into archer, fire, frost, arcane, and other unique tower forms, then improve damage, attack speed, critical chance, and range separately. Waves become larger and more dangerous, with a boss arriving every fifth wave. Optional rewarded ads provide gold, boosts, protection, revival, and four temporary spells. Progress is saved automatically, and a defeat lets you retry the current wave.
How to play
Tap an empty position around the castle to build a base ballista. Tap a placed tower to open its radial evolution and stat upgrade wheel. Upgrade the castle with the bottom button to increase its durability and automatic magic attack. Waves begin automatically after a 20-second break, or you can launch them earlier with the wave button. Tap the castle to open the four-spell rewarded magic wheel. Icons on the right provide additional optional rewards. Use the mouse on desktop and touch controls on mobile devices.
