Light glaive grid all the way.

Tho, I've already got 2 shamash books and 2 tish spears.

Arthur randomly has synergy with Tish, drop excal on turn 1 and then TA with 105% attack buffs like a bulldozer. Could even use that vigor EX skill just for the lolz.

Too bad Shingen's too good, next UE needs arrive already so that I can unlock her.
