Three things.

1.) Healing Water: I'm not entirely clear on what this is actually capable of healing. Does it just heal skin and soft tissues (so it can't heal muscle, bone, cartilage, nerves, or organs)? Additionally, you didn't really specify what the "water" aspect of this spell is. Also, is it not being able to heal the above because the spell only has a certain capacity for healing, or is it because Erin just isn't very good at any of her spells yet? If it's the latter then I need you to specify the upper limit of its healing potential.

My suggestion: Say the spell has the potential to heal anything EXCEPT for bone, nerves, deep muscle damage, and organs (meaning it can heal light muscular wounds, skin, and cartilage). The reasoning being that the spell uses water as a medium through which to heal and you don't want water getting super deep into someone's body and causes complications.

2.) Waterfall: How does the water protect the target if it is just a drizzle? Is the water sort of like an enchantment that--while it's on the target--simulates armor or did you just not describe it properly and you meant that the water is pouring down around them so fast that it can slow down, stop, or deflect a few attacks for a brief time?

My Suggestion: Make it the former, meaning it's a sort of "enchantment-like" spell that applies simulated armor on the target so long as the water remains on them (if the water is evaporated or hit off then the spell weakens and eventually fails).

3.) Ifrit's Heart: I need a maximum radius.

My Suggestion: 2 meter radius (6 foot radius).
