Does Scholar Really Use Magic? see this translation (japanese):

Adloquium is 鼓舞激励の策 (kobugekirei no saku) - "encouragement plan"

Succor is 士気高揚の策 (shikikouyou no saku) - "morale lifting plan"

Leeches is 生命浄化法 (seimeijoukahou) - "life-purifying method"

Sacred Soil is 野戦治療の陣 (yasenchiryou no jin) - "battlefield medical treatment circle"

Lustrate is 生命活性法 (seimeikasseihou) - "life-refreshing method"
So, this abilities do not seem to magic spell, but combat strategy.

in lore, does scholar use magic to heal or create shields?

how should we see (RP side) the use of these skills?
