Just adding my 5 cents as well since I've been doing him every day for over a week now. Same team, never failed me so far.Tranquil Mechanical Yeti
Start with Call Lightning, will get swapped.Son of Animus
Interrupting Jolt - Metal Fist - Siphon Anima - Metal Fist - Metal Fist (sometimes u won't get second fist off)
When Son of Animus dies, swap the yeti back in and hit Ion Cannon. Oondasta might actually die at this point already, if not the 3rd pet will do the job.Blue Clockwork Rocket Bot
That should be enough unless you are very very unlucky. I tried Missile instead of Toxic Smoke before but missed a few times (even though it's a 90% chance). Lil' Oondasta is quite slow so all my pets go first. Since all are Mechs they do extra dmg (vs. Beast) and get the extra round after dying.
