This spell enables the caster to enchant a chest, book, package, or any other nonliving object no larger than a 5'x5'x5' cube. When the enchanted object is touched by anyone other than the caster, the apparent weight of the object increases, becoming 2-5 (1d4+1) times the weight of the person or persons touching it. This condition makes the object extremely difficult to move for anyone but the caster. The caster can move the object normally throughout the duration of the spell.
The material component is a lead ball.
Notes: Uncommon for priests with access to the sphere of Wards (ToM).
High-Level Campaigns Rule
Weighty Chest: The weight increase created by this spell is activated only when a creature other than the caster attempts to move or lift the protected chest. It is not possible to use a weighty chest as a weapon. For example, the caster cannot cast this spell on a small coffer and then toss it at an opponent, hoping the foe will be bowled over or unbalanced by the coffer’s great weight. Note, however, that a foe could be tricked into attempting to lift or move the chest.
