After a number of rounds of testing, I believe that the Animatus will only steal a trait from the 5th team member while Animatus is in the first slot. Could be intended, but it isn’t explained in the tooltip. If Animatus isn’t in the first slot, he receives no traits.
You’re right. That’s definitely not ideal, so I’ll fix this in a future patch.
Thanks so much for the prompt reply!
This is also true for the animator perk “endowment” the animus has to be in the 1st slot for the effect to work.
