Not even sure if I'll be able to cram this all in:

Half Elf, Rogue Dil
6 Artificer
12 Ranger
2 Fighter

Battle Engineer, Arcane Archer

Would 6 Artificer/12 Fighter/2 rogue work better & go elf over half elf?
Does Fusillade & Manyshot stack with Fighter Haste Boost/Rogue Damage boost?

Someone has already done this build I'm sure, but my search-fu is weak today for some reason.
