She doesn't need to use Excalibur in quick succession at this point. Archer and Rider seem to be pulling out. I have no idea how Berserker's holding up with his master like that, which leaves Lancer and Saber.
Saber's healed now and Lancer's down to his one lance that negates magic. We're back to the same situation that we were in during the battle at the container dock before Lancer retrieved his second spear, if we're to assume their energy states are comparable.
Saber's used a ton of mana for Excalibur and also exerted herself fighting those tentacles, but so far Lancer hasn't really shown that he even uses mana in the first place.
wtf took down Gil? Purple smoke?
