I recently invested a bit on s tana and gave her a bladetome and ive been realy liking it. Ive been wondering what are some other good blade tome users and what units go well with them to provide buffs.
In general units with high atk/spd.
Fliers and cavaliers are generally better than infantry. Because they are easy to buff and they can reach their enemies better.
One special case is Odin. He has a unique bladetome that allows him to get easy buffs and give em. Also he doesn't have the longer cooldown the other bladetomes have
Red - Summer Tana is the best Bladetome red mage. She's flying, so she can receive buffs easily from other flying units (Hone and Fortify).
Green - Olwen doesn't have the highest speed stat of the green units, but she has a prf Bladetome without the cooldown penalty, and, if we're being perfectly honest, Bladetome units don't need that much speed to begin with if they're being used for Arena.
Blue - Summer Camilla or Love Abound Lyn. They both have the same speed stat and have easy access to all the buffs they need since they're flying and armored respectively.
Non-infantry units are easier to buff in most cases, so the best bladetome users are non-infantry units with high Atk/Spd like WT!Olwen, S!Camilla, SF!Nino, S!Tana, S!Corrin.
If you want some cheaper alternatives, you can try Aversa, Tailtiu, M!Morgan and Nino.
For buffing non-infantry, you'll need one each of fortify and hone of their respective movement types (Hone Cavalry, Fortify Cavalry, etc.)
For infantry, you'll have to reach +6 through tactic skills.
