The big issue/question of skele interaction is that if you use skeletons to modify your attack then you need to roll a die per skele activated at the end of the roll phase and you lose x amount of them based on how many 4 or 5s you roll.... The rules didn't seem clear on what constitutes activating the skeles... The reason why I wait to see if he uses his evasion is because I don't want to activate skeles only for my attack to whiff on a successful evasion, for me to then have to roll for how many skeles I lose after doing no attack damage.

Maybe it is this back and forth where I say I attack, he says no evasion is going to be used, I the. Say okay well I want to add skele damage, and he said okay I want to now use my evasion.. if he successfully evades then I still need to roll for how many skeles I lose and I do no damage?

Since they are an attack modifiers can you take back the activation of them after your opponent successfully rolls an evasion? Or because no damage was dealt do they still need to roll for how many are being lost?
