Since Rhynex is pretty fragile by default for its low health and strength, you would rather apply 3 Team Speed since he has pretty good speed stat that doesn't need anything personal and can help your allies do a better job if they're better monsters competitively.
Sparks Beam (40 Thunder damage + Burn 19s, 2 CD). Force Nature (AoE 25 Nature damage, 37s, 2 CD). Wrath of Thor (AoE 25 Thunder damage, 37s, 2 CD). Thunder God (60 Thunder damage,16s, 2 CD). AoE skills have high stamina cost, low damage, and don't apply any statuses. Can breed two legendaries (Nemestrinus & Clivia). Handy special (Double Life + Shield + Taunt). Not a great monster competitively, but useful for beginners. Its skills consist of applying Burn, Poison, and Slow on one enemy, and some AoE skills, which are pretty useless, concerning its awful strength stat, low damage, and has no effects, unlike Rabidex, which its AoE skill can apply Slow and it's slightly stronger. It has mediocrely-bad life and strength stats, but amazing speed stat that can outspeed its enemies though.
The Rhynex is a fundamentally faster and bulkier, but fragile, cousin of Rabidex that anyone can easily obtain it via breeding.
Still, he makes a good companion, especially when the power is out. The Rhynex’s horn packs a seriously high voltage punch, and he is not afraid to charge. Electro-charged stomping power, pure and simple.
