right now the archers have been left in the dust completely by artificers
AA the once best PrE for ranged combat has lost its shine but more importantly its dues
there are many things that artificer's get that an AA could only dream of
so lets look at AA's completely and see what they could do to upgrade them and how to balance them
AA imbues
weak ones include Force Burst, terror, and Flaming burst
i personally use acid imbue til about the time i get myself slaying imbue
terror/flaming/force burst are all in between these so i suggest they get up'd a lot
force blast for T4, wheras the terror arrows get the PK affect that well Terror has now (the DC)
flaming burst truly needs an overview though as i think that force the T1 is better
i think an imbue that is dependant on base class should be here
cleric/fvs get Imbue Light 1d6 light dmg and 3d6 vs undead
Fighter/barb get bleeding arrows?
bard gets imbue screaming
rogue gets imbue deceptive?
clearly i havn't figured em all out, but thats the idea look at a portion of AA and get it fixed
oh and let us start with +2 and advance to +6 arrows
