Keen Senses. Lo'Nimbus has advantage on Wisdom (Perception) checks that rely on sight, hearing, or smell.

Magic Resistance. Advantage on saving throws against spells and other magical effects.

Limited Telepathy. Lo'Nimbus can magically communicate simple ideas, emotions, and images telepathically with any creature within 100 feet of it that can understand a language.

Familiar. Lo'Nimbus can serve another creature as a familiar, forming a magic, telepathic bond with that willing companion. While the two are bonded, the companion can sense what the dragon senses as long as they are within 1 mile of each other. While the wee dragon is within 10 feet of its companion, the companion shares the dragon’s Magic Resistance trait. At any time and for any reason, the dragon can end its service as a familiar, ending the telepathic bond.

Lightning Breath (Recharge 5–6). The dragon exhales lightning in a 30-­foot line that is 5 feet wide. Each creature in that line must make a DC 15 Dexterity saving throw, taking 15 (3d10) lightning damage on a failed save, or half as much damage on a successful one.

Tazer Tail. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 6 (2d4 + 2) piercing damage, plus 4 (1d6 + 1) lightning damage and the target must succeed on a DC 15 Constitution saving throw or be knocked prone. If the saving throw fails by 5 or more, the target falls prone and is stunned till the end of its next turn.
