Best Pet for mage?

[Befs]

Passive isn't too big of a deal. I tend to focus on aesthetics for the most part there. You'll be A-OK with Mishi.

*It may be worthwhile to invest in a pet like The Re-Gifter / Chester for its gold loot passive though. (Get 'em while they're cheap)

Hiberio is great as a happiness bonus, though Electra is better outside of elite maps. The only high-end pet that I'd really say to replace either with is Lancelot once you can afford that. (Also Ingot and Chunk if you find yourself playing against elite bosses).

For Arcane Ability the response that you'll tend to get is either Nekro or Glow for the most part. Nekro has consistently been the go-to for years now, as his shield makes a huge difference when trying to stay alive, and he also has a decent chance at banishing or stunning mobs (anti-stun is very useful as well). Besides Nekro, some useful options are Shady and Surge along with lots of boss damage pets such as Werewiger, Fatima, or Belial.

One AA that I've been toying around with recently is Arcanite Arie. It gives damage reduction, speed, and health leech. The health leech is actually quite powerful, especially as a mage constantly dealing DoT to multiple enemies. I found that as long as I don't get one shot, and I keep attacking, I'm essentially invincible throughout the duration of the ability. So if people in your party already have the basics, this could be a fun pet to toy around with.

Feel free to shoot me a pm if you have any additional questions or find me in-game and I'd be happy to help. IGN - Coolguymage

Edit - I also really like munch mouth as a relatively cheap option for AA when clearing mobs. Very good chance of banishing mobs.
