Know Weight (Wizard Spell)

When the know weight spell is cast, the wiz­ard use it to read weight for one individual or object or compare weight for two, determining if one is strong enough to carry or support the other. The caster can use either spell function as he desires, deciding which function to use on a round-by-round basis.
Read Weight: By touching the subject and concentrating for a round, the caster knows the weight of an object or creature. The reading gives the total weight, including the weight of all items carried or supported. A different indi­vidual or object can be examined each round. The maximum weight that can be read at 1st level is one-half ton (1,000 lbs.) and the amount doubles each level thereafter, to a total of 256 tons at 10th level. If the weight of a creature or object exceeds the caster's capacity, only that fact can be determined.
Compare Weight: Alternately, the wizard can test the weight of creatures or objects against each other. He grasps one with his right hand and another with his left and holds them for a round. This reading determines if the left-hand subject can bear the weight of the right-hand subject. The answer is given as a short reply (see table).
For this use, success is the chance that a weight-stressed object will hold without breaking as decided by the DM. Movement gives the effect of carrying a burden on the individual who will bear it (a "physically dangerous" burden runs the risk of a disabling a character or possible death by exhaustion for mounts and pack animals-the nature and chance of injury is up to the DM). Reading is what the caster learns. This use of the spell does not reveal the actual weight of either subject.
Success(Object)	 Movement(Creature)	Reading(Caster)
100% 	Normal movement 	Yes
75%-99% 	Encumbered movement	Probably yes
40%-74% 	Heavy encumbrance 	Possibly yes
01-39% 	Burden dangerous 	Probably no
0% 	Cannot be lifted 	No
For example, Redolent the wizard grasps a heavily armored fighter with his left hand and a rotted bridge with his right hand. His answer is no. Then he realizes the fighter obviously can't lift the bridge and switches hands. He gets a yes answer and tells the fighter it is safe to cross. Then he lets go of the bridge and con­centrates on the fighter, then on a halfling and on an elf who are with the party. From this he learns the halfling and elf have a combined weight of less than the fighter's, and can thus, safely cross together.
Notes: Uncommon for diviners; otherwise rare.
