REVERIES are attachments for your REVOS which give them increased ability or different physical characteristics. They will drop randomly from defeated Monsters or Sector Bosses, or can be purchased with ORBS in the SHOP.
GHOST! Reveries, when attached to their host REVO, allow it to pass through Monsters but not Sector Bosses. They also move a little bit slower. The advantage to this Reverie is to allow your REVO to do damage in a line and escape from the top of the Sector faster so that the cooldown process can begin again quickly. It's also a little easier to rack up some additional Combo Points since the chances of hitting a wall are reduced since it will not be bouncing around from enemies.
CLONE! Reveries do not change the physical characteristics of their host REVOS too much, but will spawn a miniature clone REVO (up to 3 at a time per REVO with Reverie attached) that will also bounce around and cause damage. The damage is less than a real REVO and do not accumulate Combo Points when hitting a Monster or reset Combo Points when contacting a wall.
As the world of phobium evolves, more REVERIES will be added to add even more playstyles to your favorite REVOS.
