How to beat Sewer Clam

  • It is a clock: nothing removes Pressurize's Strength, so the damage you take doubles by turn five, while its Block is largest early and fades.
  • HP: 56 (58 at Ascension 8+). Trade damage early even through the shell, since waiting for the Plating to run out costs more HP than it saves.
  • Weak: worth a lot here, since every other turn is a Jet.
  • Pressurize turns deal no damage, so they are your setup turns.

Notes

  • Normal Underdocks encounter, always alone.
  • The chunk lists Plating with no amount; the code applies 8, or 9 at Ascension 8 and above.
  • Pressurize's 4 Strength is fixed at every Ascension and only Jet scales.
  • Plating's Block is gained at the end of the Clam's turn, so it is always up during your turn.
