I apologize in advance if I had missed the answer in any plainly visible rules/instruction areas; I did look.
Anyways, I was curious on how this actually works. I -think- I've seen it occur for others, but not myself. That is, I've seen someone cash in their spoils multiple times before anyone's turn, and that it is usually after eliminating a player. That lead me to assume that you would 1) Take the eliminated player's spoils, and/or 2)Cash in another set for more troops to attack in the same turn.
I am rather confused about this because I have just recently eliminated a player, but nothing out of the ordinary occurred as opposed to what I had seen before.
