Hmm....lets give it a try.
1. The ability to heal anyone, by giving them my energy. (Many examples, lets say for example Wendy from Fairy Tail)
2. The ability to become incorporeal at will, and negate all kinds of damage...with the downside of being unable to deal damage myself.
(Any anime with ghost/incorporeal characters)
3. The ability to create barriers which are able to withstand attacks, and to manipulate them as I see fit. (Bartolomeo from One Piece, for example).
So in summary, healing, barriers, and phasing.
At the start of my adventure I would only be able to use one at the time, but
later on i would become stronger and be able to use 2, or all 3 together if I wish.
