   {the target's Strength or Speed Bonus reduces by \arabic{spelllevel}}% Description
   {
     The caster insults the targets' diminutive build (even if they happen to be tall and strong), and they begin to whither, becoming unevently thin.
-    When the caster target's Strength, targets may find that they cannot properly carry the weight of their own armour, or weapons.
+    The target takes a minus \arabic{spelllevel} penalty to either Strength or Speed (caster's choice).
+    If Strength suffers the penalty, the target may find that they cannot properly carry the weight of their own armour, or weapons.
 
     The Attribute penalty returns at the same rate as lost \glspl{hp}.
