I'm one of those people who missed the black kat events, so now I'm trying my best to get the hats.
It's really hard now (my guildmate says) because the spawn rate before was greater than now D:
OOO can you please increase the spawn rate :O
OR
Allow us to use teamwork and invite each other when we encounter a black kat!
I do agree that the spawn rate of the black kat is low, however...
Since we have free elevators, you could do Dark Sun gate (Or whatever the name is) candles keep.
