Reactions

Spell Reflection. If the burakin makes a successful saving throw against a spell, or a spell attack misses it, the burakin can choose another creature (including the spellcaster) it can see within 120 feet of it. The spell targets the chosen creature instead of the burakin. If the spell forced a saving throw, the chosen creature makes its own save. If the spell was an attack, the attack roll is rerolled against the chosen creature.

This underwater monstrosity appears to be a giant lizard with ridged spines along its back. Six long legs along the underside of its belly, with webbed claws, propel it along the ocean. Its massive tail sweeps behind it and causes it to move with an insane speed. Once this creature finds prey, nothing will stop it from catching it.   It is said that this was created by one of the High Masters of Aquaycia to fight against their enemies. Their first mistake was creating a creature whose scales could deflect magic.
