-    The targets take an immediate \arabic{spelllevel} \gls{ap} penalty.
-    However, they can try to wriggle free of the warping effects of their own weight, by spending \pgls{ap}, or more.

+    The caster guides and enhnaces any attack at \spellRange\ -- usually an arrow -- granting a +\arabic{spelllevel} bonus to hit and Damage.
+    The caster must throw the spell while they hold exactly the same number of \glspl{ap} as whoever looses the arrow (or swings the sword).
 
+    The caster cannot use this spell to attack directly, as they cannot attack at the same time as casting.
