Like the Braid of Dire Shifting except it reduces instead of enlarges.
(Effects of Shrinking) The target gains a +2 size bonus to Dexterity, a –2 size penalty to Strength (to a minimum of 1), and a +1 bonus on attack rolls and AC due to its reduced size. Wpns go down one step.
Any reduced item that leaves the reduced creature’s possession (including a projectile or thrown weapon) instantly returns to its normal size. This means that thrown weapons deal their normal damage (projectiles deal damage based on the size of the weapon that fired them).
