Energy Orb,Chain Lightning and HT Hitbox.

Hello there fellow Arhcmages(I/L) I would like to ask you something.
I have tried the skill Energy Orb from buccaneer on certain bosses and on regular mobs, it works similar to the skill Chain Lighting that is why I want to ask you about it.
For some reason in HT is hard or imposible to hit more than one part with it, it doesnt event go from wings to arms, in Zakum arms you can hit up to 2 arms with it and in regular mobs it goes crazy, it even can go down in paltforms in skelegon maps (my record is 2 platforms down). How does Chain Lighting work on those situations, does it has more range? the damage loss is the same (2/3 reduction on orb)?
Let me know, than yo ufor your time.

 

The formula at ayumilove is:
Chain Lightning: 0.7 ^ (ordinal number of hit - 1)
Cumulative damage = 3.333 * (1 - 0.7 ^ (total number of hits))

Energy Orb: 2/3 ^ (ordinal number of hit - 1)
Cumulative damage = 3 * (1 - (2/3) ^ (total number of hits))

So im not sure if It needed a fix. I mostly use orb as a 1v1 skill but this could be a neat adition.
HT hitbox is very weird and I would like to know if the velopers know about how It actually works. The thing is that HT has a hitbox in the midle that certain skills must hit to work (dispel,power crash,threaten,etc) I wonder if that hitbox is what orb looks for instead of the others when It bounces and the only parts that are touching that hitbox are the tail and miedos head.
This skill is still a 1v1 skill for bucc and a decent skill to mob with if you combo with dragon strike, but damn the wonyness of the hitboxes and how the skill worked got me curious to ask ppl about It.
Thnaks for the details tho

 

I wonder how cool It would be if orb and lightning went nuts on HT and Zak arms, hitting everything. They lose dmg for every bounce so is not op

 

Interesting both seem to lose half damage for every bounce. Any clue about the range? I think it may be most likely how big bosses with multiple parts are aranged.

 

What is a fact is that all HT parts converge on the middle but there is no hurtbox beside the legs there. Seems that certain skills must follow that middle box (dispell,threaten,etc..) including skills that link hit to hit. Now I have more questions: Do sumons manage to hit more than one part ar the time with these hitboxes? I remeber seing a bahamut not hitting the left head at all even tho the bishop was near, and once It was very close it hit the middle head (the same that orb has no issue targeting).
