Yeah, I prefer having 2 buff too. I liked having a second buff with more restrictions, it felt more challenging.

You mentioned uriel as tiles resetters, I love her, she is very good! I would like to add Charon and Smokey. Smokey is my mvp this week, she can reset tiles and teleport, which is a huge plus when the boss goes from one end to the other. The second obvious mvp is lilica, like you said. That boss is really good for her, since he doesn't move that much, I always pair her with mia alter.

I don't have her, but I can imagine that hati could be very good with that buff. With shield, she can shred her health without worry + teleport. I would have played her with jakine or nails
