Rkhet said:Given
a) medium-sized humanoid, preferably one of the standard races
and
b) wielding a medium-sized non-reach weapon
Is it possible to get 15" or more reach?
Mouseferatu said:Dragon #331 has an article called "The Point of Pole Arms." The stats for the awl pike give it a 15-ft. reach, but it cannot be used against opponents 5 or 10 ft. away.
Rkhet said:[...] I'm more looking for spells and Prc abilities that grant reach, while being medium-sized (so no size-enhancing effects) and wielding a normal weapon (say, a longsword).[...]
Rkhet said:Ah, interesting. But that's only +5 feet. Anything else that's similiar?
