Re: [DMM] Tentacles Tactics
Event item drops are random and isn't marked at all. So the only way to find out if you get some is by finishing the stage itself and getting into the loot screen. So far from what I see, the harder the stage (higher leveled), the more books it gives. For example, I got 3 books from 18-6 (un=known), and 4 books from 21-6 (Space Sheriff). Worst part is that there's no guarantee it will drop. In any case, good luck to everyone attempting the event (me included, lul). Its going to be a hard one from what I see since it will involve a lot of grinding.
Edit: They're doing a maint so they're probably going to change a few things regarding the event (hopefully make it easier to obtain books seeing how we'll need hundreds to finish all three areas).
Edit again: Saw some posts regarding White Black. She's my very first SR so she holds some sentimental value for me. She's pretty decent in both PvE and PvP, mainly due to her high attack, AoE and immunity to debuffs. But like some people said, her biggest drawback is her very slow speed. Other than that, with good allies (i.e. Valentinus' buff or the Buff Skill) that can cover her weakness, she can be great.
