Actions/Abilities/Traits: (D&D 5e)
Action
Bite
Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage plus 9 (2d8) poison damage, and the target must make a successful DC 12 Constitution saving throw or be poisoned for 1 minute. While poisoned in this way, the target takes 9 (2d8) fire damage at the start of its turn. A poisoned creature repeats the saving throw at the end of its turn, ending the effect on a success.
Action
Searing Breath (Recharge 5-6)
The uraeus exhales a 15-foot cone of fire. Creatures in the area take 10 (3d6) fire damage, or half damage with a successful DC 12 Dexterity saving throw.
Reaction
Bonded Savior
When the uraeus' bonded ward takes damage, the uraeus can transfer the damage to itself instead. The uraeus' damage resistance and immunity don't apply to transferred damage.
Special
Flyby
The uraeus doesn't provoke opportunity attacks when it flies out of an enemy's reach.
Special
Ward Bond
As a bonus action, the uraeus forms a magical bond with a willing creature within 5 feet. Afterward, no matter how great the distance between them, the uraeus knows the distance and direction to its bonded ward and is aware of the creature's general state of health. The bond lasts until the uraeus or the ward dies, or the uraeus ends the bond as an action.
Actions/Abilities/Traits: (Pathfinder 1e)
Special
Breath Weapon (Su)
Once every 1d4 rounds, as a standard action, a uraeus's head can expel a 30-foot-line of poison. All creatures in the area are blinded for 1 round and must save against poison (Reflex DC 15 negates both). As a full-round action, a uraeus can either expel two lines or bite with one head and breathe poison with the other. Each head tracks its breath weapon's availability separately.
Special
Poison (Ex)
Bite or breath weapon-contact or injury; save Fort DC 15; frequency 1/round for 2 rounds; initial effect blinded and paralyzed for 1 round; secondary effect blinded for 2d4 rounds; cure 2 consecutive saves.
