I'm confused about Theurgical Elemental Summoning.
TCTC lists Theurgical Summoning as an option for a Sahir's summoning art, and that plus other references had led me to believe that Theurgical Summoning could summon any spirit with strong elemental correspondences (fiery afrits, the ghost of a drowning victim etc.).
But I just reread the description in HMRE and it seems to say that you can only summon fairly basic elementals (what I think of as D&D elementals) that are just animated masses of the appropriate element.
Was there a change to how Theurgical summoning works?
