Two ideas:

Red Rain becomes a Pseudo-Invocation.
- Costs 6M+
- Costs 20% of your maximum HP.
- All battle tiles become Red Rain. It can still be dismissed by certain effects such as Air Pressure.
- Every round it inflicts Claret Call normally, no changes. But if an enemy already has Claret Call, it additionally deals Water and Dark damage X times (X = Rising Game LV) scaling on (Claret Call LV * 2).
- Duration becomes a maximum of (Rank) rounds.

Red Rain generates around the Ghost every round start, instead.
- Instead of being a localized and sluggish field effect, it merely spawns on top of the Ghost every round start.
- Every round it inflicts Claret Call normally, no changes. But if an enemy already has Claret Call, it additionally deals Water and Dark magic damage X times (X = Rising Game LV) scaling on (Claret Call LV * 2).
- While in a tile with Blood Rain, all HP costs for Ghost skills are halved. This also affects friendly Ghosts!
