Reactions

Flaming Disruption When he is affected by a spell effect, he can use his reaction to use flame breath(cannot be used for anything else). This flame disrupts the spell, if he rolls damage higher than the spell DC he gains advantage on the save. If he rolls damage higher than the spell attack, he burns the attack away. The spell caster then takes half the damage as magical fire damage. The damage is 4d6 4d6 magical fire

A strange mix between a scorpion, a bear and a humanoid, the myrman is not a naturally occurring creature. It is in fact a cursed humanoid, someone who was overcome with greed or a lust for power and so a being of great power placed the curse upon them (this can be a divine being or a powerful spellcaster)
