Thanks for the feedback. Good ideas there. (Like a hand-off aura the weapon gains from the host.)
Yeah, I'm not wanting to give "extra" powers, I'm trying to "define" how it works.
Sure, we could say "just treat it like a sword shaped person and be done with it".
I tried to say Detect Presence (as used in RM) could not work. You only get a 5' rad, Yes or No (if I recall the spell correctly). Not good enough for melee.
Treasure Companion: Weapon Effects V
Guardian Defender- fights with 1/2 user's OB (AT 20 and 75 DB) for 1 hr if user KO'd or dead. Must have Low Intelligence.
If the user is blind, would the weapon zero in/target the sounds of someone moving? Could A LOUD sound then reduce it's OB?
The old blind beggar/monk with a Guardian Defender staff is protecting the temple. Is his stick blind?
If the weapon is keeping attackers at bay for an hour (!), then I need to know what happens before the players pull some shenanigans.
I like these GM exercises. They help define my world for the players. Even if the players don't know the hows and whys, it makes for a better game.
Can't believe it hasn't come up before..
