Frontier Shrine (Merciless) is one of the many Enigma Stages.


  • Infinite Relic Doges spawn after 13.33 seconds400f, delay 13.33~20 seconds400f~600f.
  • 1 Lowkey spawns as the boss after 13.33 seconds400f.
  • 6 Sir Rels spawn after 26.67 seconds800f, delay 23.33~33.33 seconds700f~1,000f.
  • 1 M. Ost spawns after 66.67 seconds2,000f.
  • 1 Haniwanwan spawns after 66.67 seconds2,000f.


Although the stage may seem threatening, it is actually really simple, especially if you already have good UL Legends (such as Naala or Doron). You also don't need to use Octopus Cat, since M.Ost will constantly knockback your units, preventing Haniwanwan from creating waves. LD Units are also recommended, to deal chip damage to Lowkey or Haniwanwan. And since the stage is time-based, you can use Worker Up Combos to make the stage easier (the best ones are Offshore Accounts and Don't Mess With Me!). After beating the stage, enjoy your Relic Orb!
