Charos is definately a figure you don't want to take lightly on the battlefield. He is a straight up beast!!!!
Even though he is 210 points and is almost half of the standard 500 point army, he is well worth it. Counterstrike allows him to wound/kill figures without having to put any order markers on him. If you draft Eldgrim and put him on Charos, you have 6 move flying beast that can reach you from almost anywhere! With his attack of 5, he will be able to wound a figure or kill them every time you put an order marker on him(unless they have a much higher defense or if you whiff)
*Note to self* Draft Charos more often
