Possible follow-up: Psychokinetic Chain does not transfer damage from electroshock generator and pneumatic hammer either, although this might be working as intended? The Chain's effect states that it transfers all direct mechanical and electrical damage, so if electric shocks and pneumatic procs are supposed to be treated as indirect damage then it's all good. At the same time, damage instances from spikes on armour or boots do get transferred properly, so it is a bit peculiar.
All in all, please make Psychokinetic Chain recognise Force Emission's damage, so that 5 separate instances of damage done to the first link - punch + armour spikes + boot spikes + Force Emission + Proxy's copy of Force Emission - could turn into 40 received by the fourth (or between 56 and 62 with Power Fist's assistance, which would be exceedingly funny).
