Flying Mines are the first type of mine the player will encounter. They first appear in the depths of the Daea dungeon, just before the secret entrance to the Prince Tower. They are especially prominent in the Prince Tower and the Phoenix Lab.
Flying Mines are stationary at first, usually situated on a small platform, but will take flight once Gale gets close enough to trigger them. Once a Flying Mine activates, a timer will start ticking and it will fly towards Gale, exploding either upon contact with her or after a few seconds when the timer ends.
To deal with Flying Mines, the player should either run away or push the Flying Mine away using their melee weapon, the Slingshot, or the Javelin. Flying Mines will try to reach Gale using the shortest path, meaning that they can become stuck or impeded by walls and other obstacles. A bomb or charged Javelin can destroy Flying Mines before they activate. Using the Javelin to knock one Flying Mine into another will also cause them both to detonate prematurely.
Rollo Mines are the second variety of mines. They first appear in the Dread Lands and are most prominent there. Rollo Mines are hidden underground at first, but when Gale gets close enough they will emerge and start to roll downward in Gale's general direction. They explode either on contact with Gale, with each other, or when they hit a dead end. They tend to appear in large numbers on both sides of Gale, but are really only dangerous when they catch you by surprise. Areas containing Rollo Mines are usually marked by the dead grass floor tiles. It's worth noting that a Rollo Mine's explosion is much more powerful than a Flying Mine's.
Rollo Mines also return in the Phoenix Lab, but only as part of a puzzle where you must guide a Rollo Mine to an out-of-reach switch to open a door for you.
Harpies can also grab a different version of Rollo Mines from offscreen and use them as projectiles to drop on Gale. Whereas the original Rollo Mines have a brown, rusted appearance, these Projectile Mines are vivid blue.
Flying Mines will return in Phoenotopia Awakening. Aside from new graphics and a new name, they will be pretty much the same as they were in the original game.
Rollo Mines will also be returning in the remake, with new behaviors to boot. They will be much more dangerous in this game, as they can now emerge from ceilings as well as floors. Additionally, their explosions now send out shrapnel to increase the chance of landing a hit.
