My response was mostly to the statement that healing is improved in this write. I'd agree that at least witch doctors should not have immense healing abilities (although most healing magics already just heal over all injuries without lingering effects.) Healing in the current write is vague and frustrating, but it does work effectively.
The ability functions almost identically to voidstalker withering, but halved, hence the comparison. It would be better for the magic to be stronger in other areas than have a spell which is too ineffective to be useful.
In addition of the many instances of orc witch doctors I have seen in crp, all but two have used curses in crp that I witnessed, and the one of them who wasn't was powergaming a different part of the magic. The 'casting at a range is fine' implies that the spell can be cast so long as nobody does anything to interrupt it. If this is not the case there is a serious amount of powergaming going on in the magic.
All of those methods are interesting, but in my opinion none of them are still as compelling as a spirit walk (and should not be limited to just farseers if its a stand in for the central point of shamanism.) I'd still heavily encourage at least an option to perform a spirit walk without needing the soul to go to the realm. Maybe say greater spirits cannot appear/the scenery feels dreamier/people will look like they do in the mortal world/spirits can't tell if someone's soul is tainted while the soul remains in the body. Allowing both options would be the best solution to preserve the centrally important spell while also fitting into LT demands.
You can use use current cursing for hallucinatory visions, elevating painful sensations, changing a persons perspective, etc. This version lacks much of that. Soft-pking as well, while possible technically, is not practical since the person has to choose the effects of the curse themselves and hexes have to be directly approved by ST. The new redline preventing people from making it so characters cannot interact with others certainly fixes this concern though!
This would not spot people from doing it, and it still cuts off a large number of prophecies for no reason. I don't know what the point of removing player made prophecies is.
A lot of the other changes look good though! I'm definitely feeling more confident about this write helping the communities.
