How to beat Fogmog

  • Every Thwack adds a point of Strength that never goes away, and Headbutt is where that Strength lands hardest.
  • Roughly every other turn is a Thwack, so the fight gets steadily worse. Kill it before Strength passes 4 or so.
  • The Eye is a Minion that dies with Fogmog, so ignore it unless 3 Dazed a turn will genuinely wreck your draws, in which case a spare 6 damage each turn silences it for that turn only.
  • Block Headbutt turns and attack through Thwack turns.

Notes

  • Overgrowth normal fight, 74 HP (78 at Ascension 8+), starting alone; the Eye is added on turn one.
  • The compendium hides both the second Thwack state and Headbutt, so the in-game move list looks shorter than the real pattern.
  • The 40/60 split is fixed; the no-repeat flags on those branches never block anything because Thwack always sits between rolls.
