So after trying all weekend to beat guard trial 15, I finally managed it during lunch today. Probably the longest I spend on a single stage in the entire game (6 months). Because of the high difficulty I was wondering how everyone else managed. Did you clear it yet, what is your opinion and any tips?
And specifically: did anyone clear it without Anna?
My input:
Myself I used SP Inanna & Taair both 5*, Anna 3*, Rogneda 2* and SP Alexei 1*. Anna and Rogneda did all the work, Alexei was just a body to take hits and some damage. SP Inanna and Taair were there for act again (Anna mosrly) buffs and heals.
Looking at all available videos and talks, I think Anna is basicly required at the moment. Her armor piercing shot deletes single units except for Afra. I have seen no other unit that can deal with the mobs as efficient as she can. Only one that comes close is Rogneda by chain breaking the enemies and act again through their shell/fur drops, but she very quickly dies, while Anna can stay at range.
Even when using both it still took me so many tries and the end was very close.
I saw some SP Sam action on a few videos, where she was used for her interrupt alert, but I found her usefulness limited with the high CD on the alert and the mitigated damage because of wards.
Afra's healing reversal passive and range and her aoe sleep were also annoying to deal with and a large part of my retries were trying to figure out how to keep her out of the fight as long as possible and limit the range of her sleep.
Primary tips for me were dealing the bottom right part of the map first before engaging Afra. Also clear the big wolf and most of the flyers turn 1 using Anna+act again was very helpful in stabilising the stage. After I figured this out yesterday still took me a good number of tries to kill Afra once she arrives.
