MagicOptional rule
Underwater Casting
Rules for casting spells while underwater.
Using a spell that creates water while underwater can be confusing. By this ruling, isntead of creating water, you manipulate the tides and send a shockwave.
When a water spell that deals damage is cast underwater, the damage turns into force damage. Also, any knockback effect from a water spell is doubled inside a body of water.
When you use magic to create a whirlpool inside of a body of water, instead of being a circle, it's a sphere.
