I've also picked Rowanna. It was quite an easy choice to be honest...
Event-wise: 504 fangs collected and I still have 17 SCs in the bag. Yet to buy any.
As for silvers, I've been grinding the black dragon cave map and I have 5 Verottes (+1 already CC'd, but I'm keeping that one) and 11 Mortimers at this point. I'm kinda thinking about switching maps. 5 pirates are not a whole lot, but it's enough to get me started. If I do that it'd be either the red dragon map or the water dragon map. I could use more silver witches and platinum armors as well. I don't need Pallis, I've already got 5 surplus copies of her, plus I have an extra Mehlis and an extra Barbastroff as well, so I'm good when it comes to mage fodders. On the other hand I have two extra copies of Calliope and that's about it.
It's a shame that both of those maps are a pain in the ass to handle. Oh, well.
