After we manage to kill Basilisk with a few wounds I realize that I spent almost all my mana and it looks like it was the same for the others.
As soon as I see everyone is fine I go to Basilisk and bite one of his wounds and start drinking his blood until I can't get any more, so I'm going to take a look at the notifications.
Ding! Ding! Ding!
