i have no problems. I cleared the last stage from xpstages.
My god is everytime active. All my chars has a spirit dmg on the 2nd skill (the green symbole).
First i look how many pointers the enemy has. More then 0 i activate both dmg features. I prever spirit dmg. I kill first spirit enemys and deactivate sword and then i kill meele enemys with the spirit or the green one.
I can show a battle on a high level on my way. its very easy and need only a good eye to prevent fails.
