The topic explaining what the DLC contains is in this previous article.
It’s now out as of right now, the short of it is, Olivia, Tharja and Owain are now playable along with several new history maps, skills weapons and costumes to get!
I’ve done a few videos showcasing their movesets for your viewing pleasure, click read more for the videos! Hope you enjoy
Olivia who has a unique style, and fights like a Ninja
Owain who fights like like Ryoma and is a huge ham
Tharja who seems to fight like Robin but it feels faster. I’ll have to compare properly when I give Astra to Tharja. Also she has a unique Strong 6 attack from Robin
