Armor of Virtue has an exploit, but it's not as described:
At the end of round 1 movement, all friendly units in the square the Armor of Virtue started in gets Ritual of Returning. (This also means that if you move in the very first turn instead of buff when wearing Virtue, Ritual of Returning doesn't stick to you.) But you could stick 6 MARKATA in that square on 'Hold','Attackx4'. And they will ALL get Ritual of Returning.
If that exploit doesn't scare the pants off you, you're probably just already not wearing pants.
