Ω Encounters

Omega bosses can appear during Chapter 2 (after Spade Magnes) and later as a random WARNING encounter. Multiple Ω bosses can be encountered in one map.

When the field music is playing a special music instead of its usual track, that means an Ω boss can be found. The music will also continue playing into battles.The chance of the Ω music occurring resets upon entering a map on the Wave Road, and only if it is different from last 2 maps. There is 1/64 chance of getting Ω music in a map, then 6/16 chance of encountering the fight. In the Planet FM Astro Waves, there is a 1/32 chance of getting Ω music instead.
