Was George Orwell an Optimist?
The yin yang token states it can be used at any time so long as it is not in the middle of an action. If I am the blue taoist utilizing the power to talk to a villager and attack, can i utilize a village square, use my token to ask for aid from another villager which gives me tao tokens, and use those tao tokens in a fight against a monster adjacent from me?
Yes, you could do that, because you are using the yin yang after one action is completed and before the second one starts. The prohibition is only on using it in the middle of an action.
