Easy Xeno-Artefact Farming For Rep

[I'm A Distraction!]

There's a certain boss fight in Chapter 4 which spawns a relatively weak enemy unit every turn for each thing you don't destroy. But each unit spawned comes with a pistol and knife, both of which are worth 10% xeno cargo, for a total of 20%, and you can get a half-dozen plus to spawn every turn.

Have Ulfar in the back to lure most of them to him, and they'll be unable to scratch him, just let him leisurely murder them (or they'll die to the bleed they spawn with), kill the secondary threat, and the boss mostly just sits there while more stuff spawns in. Repeat until you get bored. I just farmed until my MC's Sword of Faith one shot him, and now I'm leaving with 71 pistols and 71 knifes, for 14 xeno-artefact turn ins. ;D
