How to beat Fossil Stalker

  • Block is everything here.
  • One unblocked Latch makes the next Latch a 15. An unblocked two-hit Lash counts twice and adds 6 Strength at once, which is why the weak-looking Lash is the move to block most carefully.
  • Tackle's Frail makes the following turn's Block worse, so budget extra for the turn after a Tackle.
  • If you can fully block three turns in a row it never grows and dies to steady damage. If you cannot, race it, because every leak compounds.

Notes

  • Normal fight in the Underdocks act, always alone, 51 to 53 HP (54 to 56 at Ascension 8+).
  • Suck only counts powered attack hits, so its Strength gain is per hit, not per move.
