Best evolutions for deep Extinction runs

Answer first

Current community evidence supports four deep-Extinction scaling families: Toxic Sequestration poison, Primal Spur mutagen scaling, Training Stoner stat scaling, and Max-HP Body Slam backed by dense POI routing. An August 5 screenshot provides a Body Slam benchmark at Pressure 10 Extinction 8: level 403, 999 HP, 438 Plating, 452% attack area, and roughly 10,000 damage per slam. A separate August 6 Pressure 10 Extinction 20 clear combines Opportunistic and Pollinator POI growth with Primal Spur, fast Claws, and Training Stoner, reaching about 480% size and 830% attack area. For poison, Snout plus Poisonous Saliva with Spit or Jaws remains the cleaner shell because Snout conflicts with Beak and Leech.
