Pax said:Does a longspear combine with a human's 5' reach, to give 15'?
No.
An Ogre wielding a size-large longspear has a reach of 10'; for the Ogre, that longspear is no different from a Shortspear sized up to match the ogre himself.
A shortspear is five feet longer than a dagger. Does that mean that a human wielding a dagger should have 0' reach?Grog said:But it is different from a regular shortspear which only has 5' reach. The proportionate length is irrelevant - the only thing that matters is the actual length. If an ogre wielding a shortspear has a 10' reach, then an ogre wielding a longspear, which is 5' longer than a shortspear, should have a 15' reach. And an ogre wielding a huge longspear should have a 20' reach. Like I said, the spear doesn't just suddenly get shorter because an ogre is wielding it.

Technically, it means that a human wielding a dagger should have ~3' reach, and a human wielding a shortspear should have ~7-8' reach, but there's no game mechanic for that.
