Lock and Load: The Reassembled Machinist Guide

[Themis]

That 200 becomes a seperate attack which hits the main target if there's only 1 target (so 100 potency on the first hit, 200 on the 2nd). I believe if there's 2 targets it'll split the 200 potency between the 2 so 100 x2 for the first and 100 for the second but I might be wrong on that.

Initial hit on the main target is 100 potency. Then the 200 potency is split between any targets around it still alive, including the main target.

Thus, if 1 target only (the main one) then that target will take 100 + 200 potency damage. If 2 targets, main target will take 100 + 100 potency and 2nd target will take 100 potency. If 3, then 1st target is 100 + ~67, 2nd target is ~67 and 3rd target is ~67. And so on. It's overall damage won't really increase regardless of how many targets there are, and will do more damage per target the less targets there are.
