Saving Throw Fortitude
You cause the sheath of water and the improvised weapon it surrounds to surge outward with stupendous force as you attack. Make a melee Strike with your improvised weapon. The weapon then breaks, and each creature adjacent to you must succeed at a Fortitude saving throw against your spell DC or be pushed 5 feet away from you (10 feet on a critical failure). You can Stride after the target of your Strike if they are pushed but you must move the same distance and in the same direction.
If the item has a Hardness greater than your level, or if it's an artifact, cursed item, or other item that's difficult to break or destroy, it doesn't break and adjacent creatures don't need to attempt Fortitude saves.

FocusFocus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
MagusThis indicates abilities from the magus class.
WaterEffects with the water trait either manipulate or conjure water. Those that manipulate water have no effect in an area without water. Creatures with this trait consist primarily of water or have a connection to magical water.
