Attacking for no reason?
 

Yeah, I was in tormenta. And I'm fairly far away from this molusk, and it just starts attacking me for NO reason. I'm not even near it, I almost died 2 times cuz it was so unexpected!
I was afk once...and when I came back it started attacking me, and I just killed a seabeard, far away from it, and it attacked me.
Annoying as heck!
Edit:I saw a friend get attacked by a seabeard for no reason too, same thing. She was far away from it.

Did you see the invisible/invulnerable pirate(s) on compass?

This could be of many reasons. You were either:
A: On the path of which it walks. Sometimes if you are a high level and you cross over an enemies path when it is near by it will begin to attack.
B: If you were holding a weapon this would also make it attack you.
C: If you had recently killed another enemy this might cause a chain reaction for another enemy to attack.
D: Maybe it was really grumpy because it got decaf coffee instead of regular at the Tormenta Starbucks and need to release some stress.
E: If you were facing the enemy so that you could see its health bar maybe that is why.

Other than those answers I really have nothing (In the case of any of the answers results may vary). Hope you figure this all out mate, hope i helped! Best of Luck!
