Arid Butcher Eximus - Where to find him?

[_MalgahnN_]

Hello,

I saw some old posts about where to look for Arid Butcher Eximus, so once again, i tried everything and he is just not spawning. I know he can only appear on Mars but it seem i only got one of his scans from Spy mission. Maby you guys know good places to look for him without grinding Spy mission on Mars

Thanks in advance

I found the arid enemies spawn after 5 min of a mission. So do an excavation for like 4 digs, defense past first reward, or something else to get to that time marker. They will start to phase out as the enemies get higher level so don't try to sit in there for ever. I saw a drop in spawn after 15min in a mission.

This is just what I have learned from dojo pigment farming.

Handy guide I use when I get the Simaris scan quests.

Hop into endless missions and get to atleast the second round to make Eximus spawn.  There spawn rate ramps up the further you go.   (oh and obviously going with randoms/friends will make them come earlier and more often as well).
