what i am saying is that the EoA damage can not be evaded
and if the the errow explodes when evaded, its in range of the one who evades it, to do EoA damage
however it not chain/fork/pierce any more, reducing damage if use things like chain, witch i not plan to!
i think it goes like this
if i hit a monster whit Explosive Arrow
i do phisical-ranged-bow-attack-damage, witch can be avaded
if not avaded, i make a bomb of the target, a fuse that explodes after 1 sec, visual as a burning errow
if evaded, the errow explodes and do 1 Fuse damage to EoA, but NOT do chain/fork/loh/stacks another fuse, its like shooting a tree or wall, witch damage nearbye monsters
Baleee is telling it explodes after evaded, do a visual EoA animation to enemy, but it not hits?
i_r_slayer is telling that it flies offscrean after its evaded?
mebe i am talking to match and need to do some more tests, but i think there is a confusion going arround
http://en.pathofexilewiki.com/wiki/Lightning%5FArrow50% of Physical Damage converted to Lightning Damage
Hits Additional Targets: Arrows will strike a target and up to 3 randomly chosen monsters within range of that target will also be struck for the same amount of damage (not just the lightning portion of the damage).
this means, if evaded, damage done is 0
so 50%*fisical+ele, etc etc * 0 = stays 0 for the non-evadible EoA-effect
but on explosive errow this is not the case!
i not play light errow, but can you shoot at a tree and damage nearbye monsters?

also i will mention it again
The damage of the explosion is considered projectile damage, but not weapon damage.
only weapon damage can be avaded
and for light errow, the aoe damage is based on weapon damage, witch is zero if evaded, witch is not the case for explosion errow
i always like your theory crafting and i just found that bow so i might give it a shot!
