Ophidian Brood Spawn

Characteristics

Mystic Opulence. This creature has the ability to evolve alongside its caster's progression. Starting at the 2nd level of a character with the Brood Mystic runessence, its spawn have a CR equal to half their caster's player level. With each CR increase, the creature gains 1 additional hit die and 1 additional damage die to its bite. In addition, upon reaching CR 2, 4, 6, 8, and 10, the creature gains +1 Strength, Dexterity (increasing its AC as the modifier rises), and Constitution (adding a fixed amount to its maximum hit points equal to the Constitution modifier multiplied by the caster's proficiency bonus), and its Venom's DC increases by 1.

Poison Spit (Recharge 5-6). With an action, the spawn spits poison in a 15-foot line that stops at the first creature hit. The creature hit must make a DC 11 Constitution saving throw; on a failure, the creature takes Poison damage equal to the Pulse Die of the Ophidian Brood Spawn's summoner and becomes Intoxicated for 1 minute. On a success, the creature takes only half the damage and doesn't become Intoxicated. At the start of each turn, the creature can repeat the saving throw, ending the condition on a success.

Attacks

Bite. Melee Natural Weapon Attack, +4 to hit, 5 ft. reach, one target. On a hit, deals 4 (1d4+2) Piercing damage.
