Passive is list of tasks from the lady (stuff like "Find Tomes", "Slay Elites", etc. Completing gives blessing of lady which provides buff for the one match, which affects the whole party and (Probably) won't restart after death).
Board and Sword and Bretonnian longsword are new weapons.
Grail Knight will not be able to use spear, halberd, or imperial sword and shield.
Ult is called Blessed Sword. It's a "targeted kill attack" that is a very powerful overhead slash that cleaves.
