This is available in the spelldesc branch in crossfire-arch; the tip of the branch contains the changelog entry, which I've reproduced here:
Rework descriptions of most spells and prayers. This is a large change that
has no mechanical effect, but touches the majority of spell archetypes. The
objectives of this change were:
- Accurately description (or least hint at) the spell's in-game effects
- Consistency between flavour text of related spells
- Consistency with flavour text of the corresponding casting skill
- Correct grammar and spelling
- Correct "granted by god" info for god-granted prayers
- Remove information that the server provides automatically on examine, primarily
the "attuned to path" information
I meant to do this immediately after the "display spell info when inspecting items" patch to the server back in 2020, but life got in the way.
This should be a safe change, since it contains no mechanical changes at all, but it still touches enough stuff that I'd like at least one other person to look it over before I commit.
