I’ve started doing them recently.
Built my tamers suit around casting focus, SDI, and eaters.
120 mage medi taming lore spellweaving and vet.
Spellweaving thunderstorm and essence of wind, plus teleport to get all the mobs on screen to me, invis, and let the pet do the work while I blast wildfires. Attunement helps avoid damage, and Arcane Empowerment allows super healing spells and higher SDI.
Naja with FW and PB or Mystic Goo AI Cu, depending on which champ. I only do semidar with a sampire because of her damage output, and Rikky with my thrower.
I prefer the Najasaurus because of the high dex and Resist spells.
I’ve had success with Rat champ and undead with pets. May try Oaks, but I’m not sure yet.
