Helloooo! I know, I know, I missed posting last week. I been busy, I swear! Alric and I have been busting our humps trying to track down all the creatures that you can collect animus from. We almost had them all when Monstrologist Burke added Treants, Pigs, and Gobblers into the mix! As it is, we are currently at 475 of the critters and Alric and I are currently in Crimson Fields, MooShu collecting several more to add to that.
Dezzy will throttle me if I don't post something today so I mainly just have a couple of quick lists for you. Seraphs are actually quite rare. Mainly you will only find it dropped in Barkingham Palace, The Spiral Cup Gauntlet - Tiers 4 & 5, and only a handful of other bosses throughout the Spiral. Sadly, I only currently have 6 critters in my knowledge banks. I so coulda had all 18 if I hadn't flaked on this post. Dezzy gonna sic Lexi, her pet Humomgofrog on me! I'll try to talk Esmee into helping and with luck there might be more than 6 on the list when you look at it.
Any how, personally I would prolly start with Noxious Gas Golem (hehe I'm SORRY but he just cracks me up! I mean think about it!) in Barkingham Palace, Marleybone; Othin Stormfather in Ravenscar, Grizzleheim; Jade Oni in Jade Palace and Oakheart in Village of Sorrow - both of those are found in MooShu. All of those bosses drop Seraph TC and pets, AND you can collect Treant animus from Oakheart.
