Dungeon is a room.
Gandalf is a wizard in Dungeon.
Conan is a warrior in Dungeon.

The rusty dagger is a dagger in Dungeon.
The elvish sword is a sword in Dungeon.
The oaken staff is a staff in Dungeon.

Instead of giving a weapon (called W) to someone (called C):
	consult the rulebook for C wielding W;
	if the rule failed:
		let the outcome text be "[outcome of the rulebook]" in sentence case;
		say "[C] declines. '[outcome text].'";
	otherwise:
		now C carries W;
		say "[C] gladly accepts [the W]."

The can't take people's possessions rule is not listed in any rulebook.

Test me with "give sword to gandalf / give sword to conan / give staff to conan / give staff to gandalf / give dagger to gandalf / get dagger / give dagger to conan".
