Not much of a difference except if you're using a magmaring garment. If you're then yes, it will make a tiny bit difference[still not much anyway] because different multipliers being stacked, when optimized, give better results in the end.
2scorpion+2kaho = 1.4*1.4 = 1.96
2scorpion+2kaho+magmaring = 1.4*1.5 = 2.1
2kaho+1scorpion+skel worker = 1.4*1.2*1.15 = 1.932
1 kaho+2scorpion+skel worker = 1.2*1.4*1.15 = 1.932
2kaho+1scorpion+skel worker+magmaring = 1.5*1.2*1.15 = 2.07
1 kaho+2scorpion+skel worker+magmaring = 1.3*1.4*1.15 = 2.093
2 scorpion+2kaho+magmaring would be the best but there is the factor +15atk from the skeleton worker that makes a little difference because, between the 2.1 vs 2.07 vs 2.093 mods, an extra factor attack makes a big bit of a difference.
Using a 400 atk sniper on the previous math.
2.1*400 = 840
2.07*(400+15) = 859.05
2.093*(400+15) = 868.595
So yeah, any of the 3 are pretty much ok, super small difference.
Oridecon arrows have 20 more attack so with endow they're better then the fire ones.
