Hmm. the Para/Sieg team I used for the Main stage works alright for the Finals lotto, but doesn't quite have the strength to kill Mushi unless I get a Brave chain with Sieg. Might have to see if there's an Archer team I can put together for that node, otherwise I'll be suffering 3-6turn clears for this node. D:
edit - o seems it can be done with a fully skilled Jarcher, which I don't have and don't wish to boost just for the sake of this event - even if it might enable better farming, I'm not burning all of those mats and QP for this one week of use. I'll likely stick to Sieg than.
