Turn 1

How to beat Cubex Construct

  • Two of every three turns add 2 Strength, so plan on a four- or five-turn kill before the numbers outgrow your block.
  • The 13 starting Block blunts your turn-one attacks: accept it, or open with something that ignores Block.
  • Artifact 1 stops the first debuff, so play a throwaway one before Weak.
  • Expel is two smaller hits and the turn without a buff, making it the best turn to take a little damage.
  • In Construct Menagerie there are two Cubex and a Punch Construct, so the Strength math applies twice over.

Notes

  • 65 HP (70 on Ascension 8+), fixed rather than a range.
  • It fights alone in Overgrowth and in the Construct Menagerie of Glory alongside a Punch Construct and a second Cubex.
  • The eye and moss on its shell are random cosmetic skins.
  • The two Repeater Blast states are separate copies of the same move.
