I got the NPC Codex for Pathfinder. Very cool! Over 300 NPCs for every level with flavorful names and backgrounds.
That would be awesome if Starfinder had the same thing. I'd say better than a 5th alien archives book.
Paizo...please do your magic!

Sincerely,
Loyal Starfinder fan :)

New guy here searching for an answer to the statement in the "Total Concealment" rule: "... though it can attack into a square it thinks you occupy."

What would be the DC for this attack? Or is the attack against the target's EAC/KAC?

From the CRB:
Total Concealment
If a creature has line of effect to you but not line of sight (see
page 271), you have total concealment. An enemy can’t attack
you when you have total concealment, though it can attack into
a square it thinks you occupy. A successful attack into a square
occupied by an enemy with total concealment has a 50% miss
chance (instead of 20%).

Thanks.
