So was reading about the new biohacker when i stumbled upon this paragraph.
"As long as you have your custom microlab, as a move action you can target a creature within your line of sight and within the microlab’s range (60 feet at 1st level) and attempt a special skill check to identify it. If the creature is living, this is a Life Science check. If it is unliving, it’s a Physical Science check. The DC of this check is determined by the creature’s rarity, as presented on the Creature Rarity table on page 133 of the Core Rulebook. You can attempt this check untrained regardless of the DC, and you always treat your die roll result as a 20."
Do they get a automatic natural 20 on all science rolls?
