OOC:
Right, yes, she had disadvantage, but advantage cancelled that out, so she got a 23 to hit, not 26. Even with the 26, the 27 AC from haste would have blocked it. Not complaining, but artificers are generally pretty weak except in 1 area and that is having AC higher than the gave ever had to think a player could have. this is why armorer artificers lost the shield spell, hahaha.
As for Crusader's mantle, all good. Chironides did not hit with any of the attacks, but I'll expect players to remember they can add it or that Kadmos will say "hey, you did 1d4 extra damage for each of those hits" if they forget, but i'll add it to the tracker to be safe.
Having Kadmos go first isn't an issue, except in 1 way that players could not have known about. Hythonia was going to use her legendary actions to attack the first person that attacked her and then move without opportunity attacks. If Kadmos went first, but Hythonia attacked Chironides, then the only other legendary action she could take would have been before that attack, and if she moved she could not have made that other attack. If I say it was against Kadmos after all, he will be forced to use his reaction to cast shield and spend the spell slot even though it was declared against Chironides. If you guys are ok with a little suspension of logic, I'm going to have Hythonia do her original plan, but somehow it all worked out since dice have already been rolled, so while it doesn't quite make sense, I'll say Kadmos and Chironides ran up at the same time, then Kadmos did his action, Hythonia attacked and missed Chironides, then Chironides attacked, then Hythonia moved.
