I can clear the first and second hallways but then I usually lose about 2 units during the third. I can't remember what my last party was. Anna I use for healing because she can't do much if any damage, plus to open the doors. Maribelle is also a healer. Ricken, Kjelle, Kellam, and Tharja are my biggest damage dealers but Tharja gets hit hard when she gets hit. Chrom is pretty useless but I have to use him and I've kept Nowi in for the interactions. Kellam doesn't really lose much HP at all if I can take out the mages as he only take 1-2 HP per hit. My fliers are good and do good damage until an archer gets to them.
I would wait longer but I'm out of second seals and from what I've heard, the other two towns I need to clear to get them are harder than this one so... I could just wait for more Anne's to show up I guess
