Heh, I play mostly for an option that *looks* best. I'm shallow.
It seems that the skill that the Siren is using is indeed a siege skill. I confirmed this by reading a interview about sieges that talked about how players will be able to summon creatures for the event. So it seems that big rock monster has nothing to do with your class.
Here is the article. The part that talks about the summoning is on page 2

Thanks for the link, V!
Np ! Tbh I am happy that is just a event spell and not a actual one. To many people pick certain classes because they think the class gets something op -_-.
