For a tier 1, you will get "can mesmerize EITHER animals OR humans (including or excluding numbered at your discretion) and they will remember it". To get both animals and humans, or get one and not have them remember it, you'd need a tier two.

Would any of these options work for you?

(Sorry for the delay, I wanted to look for precedence cases first so this took more time than normal echoes and Christmas was rather like a whirlwind this year)
