I can certainly offer at least a conversation about 3, Yoshitsugu here can't be 'drained' fully of his power because of how innate it is and at the most gets physically tired from using his abilities. He won't immediately turn down a useful offer either so he'll hear it out; gotta go with the flow and deal with the hand we're offered, right? ♥

Yoshitsugu is also a tease and someone like Achilles is definitely going to be a target considering that delightful mix of 1, 2 and 5.
