Any tips for fighting Hilla?

Every time the little helper person announces something, Stop attacking. If its Damage Reflect it always pops up a quarter second before the helper person says something, which will pretty much get you killed every time. All the other times its not too bad, Stay in the pentacle, avoid the tombstones, etc.

Yea but Hillia's DR animation happens before the dr takes affect so really you need to be looking if hillia starts making a hexagon shield (kinda like a BtlMs party shield but redish instead of blue) you have about 1 sec from when she start the animation to when she is DRed
