if i take a plain long bow and plain arrow, then its obviously a plain weapon.

if i take a long bow + 1 and plain arrows do they count as plain or do they pick up the plus 1 for being fired from a bow+1 (note, im talking about enchantement for hitting, i know the damage adds up)

if i take a plain bow and arrow +1 i guess its a plus 1 weapon.

but if i take a bow +1 and arrows + 1 then is it +1 or +2?

for the perpose of ability to hurt monsters, only the enchantment of the missle counts. FOr the perpose of THAC0, both enchantments are counted.
