Ice Manipulation
When it comes to offensive use cases, few facets of water magic can come close to the manipulation of ice, which covers the creation, control and shaping of ice. Initially, like all forms of magic, only small ice spikes can be conjured, but skilled water casters can control natural ice formations or form great spears of ice to launch at targets.
That said, it's not an exclusively offensive form of magic; ice manipulation can allow for the sculpting of ice into a variety shapes with sufficiently fine control, allowing for skilled
Hydromancers to create ice sculptures and such.
Liquid Manipulation
Generally noted to be the rarest and most advanced form of water magic, liquid manipulation is the ability for a water caster to extend their fields of expertise away from just water and ice, beginning to cover other liquids too. At first, a
Hydromancer must stick to learning how to manipulate liquids that contain at least 40% water within them - such as blood, though it lacks the permissive abilities of true
Blood Magic, being sharply constrained by the foundational laws of magic which makes these abilities only useful on liquids external to the body.
The best water casters can even bridge the gap to use water magic on all forms of liquid that contain even a little bit of water.
Elemental Summoning
While
Summoning Magic is the core magical overseer of the summoning process, elemental casters like those with water magic can establish a link to the elemental realm of water to conjure forth limited summons. These typically range from binding small water familiars to summoning larger water elementals.
Aquatic Travel
The
Asraiad of the waves are notable within the discussion of water magic for having distinct abilities tied to their practice of the magic, generally referring to the ability for water magic to be used for aquatic travel. This technique tends to allow for exceptional abilities to breathe beneath the waves and utilise the ocean's currents to move far faster than would ordinarily be possible, and expert Asraiad
Hydromancers can grant this power to others, too.
