Looking for Missions to develop my buffing and healing TECHNICS

[knight85]

I'm about 3 chapters away from clearing episode 1. then i'm planning to move across to episode 2 with my created character.

but before i do i'm trying to plan out what i'm going to do in terms of support technic development.

working on shifta and deband is easy. find a photon restoration node and set down to work

however things are a little tricker for developing resta.

out of curiosity i went into one of my saves and used the spell to heal ethan when he had no damage but got bupkiss.

so can anybody tell me if there are any free missions with traps or turrets where i can develop resta outside of combat?
