The Cursor is a flying enemy found in the Sun Tower. It attacks by launching a single long-range homing fireball at the player every few seconds.
A Cursor.
Cursors are at their most difficult when navigating the outdoor portions of the Sun Tower, where they can float at a safe distance and attempt to snipe the player. Their fireballs have good range and speed with decent tracking, but cannot pierce terrain. Bait the fireball into nearby terrain, or if that is not an option, force it to make sharp turns. Counterattack when the Cursor draws close.
There are 2 tougher versions of the Cursor called the Vilificator and the Maledictor.
