What does the unit actually say? It is not in the online wiki or the in-game encyclopedia yet

if [all units] adjacent to Electric Whip have [only one slot left in total]
that remaining unfilled slot will be filled.

also then, pass this effect.

I cannot figure out what this unit does, consistently.

It's written in such a way that suggests that if the units adjacent to Electric Whip have one slot left, if you fill Electric Whip then those remaining unfilled slots will be filled. But that is absolutely not what happens.

Either it's bugged or the text is very clumsily written!

Nor can I figure out what "pass this effect" means.

I tested it and it works if there is only one open slot next to the unit (all other adjacent units are fully loaded or have no slots) But I can't figure out what 'pass this effect' means and without it, it's a useless waste of 2 weight and a slot.

It sounds like whatever slot the Whip just filled, that unit is now the origin of the next whip effect. In theory it sounds like you're supposed to leave a chain of single empty slots across your units and it will fill all of them if positioned right, up to probably 6(?) if they are in a kind of C or U shape (so there's always only one adjacent empty slot each time it repeats). I've tried like 3 runs with him today but it just won't give me the unit to try out >.>

Finally got it and I was correct, if you make a single energy slot "path" for it, whatever you load will be copied along the entire path

Oh wow, thanks for figuring this out!

So electric whip won’t pass and chain if there are multiple adjacent units with a single slot free. It has to be one single slot in one adjacent unit.
