I am trying to integrate www.circlemud.org/pub/CircleMUD/submissi...kills/corpsehost.txt into my code
I am assuming that the actual ASpell code is supposed to go into spells.c which is where I have it but it doesn't seem to link up and nothing happens when I cast the spell.
I am also assume that we have to add that code instead to magic.c under mag_summons possibly? When I do it that way though game crashes

That snippet is pretty old and some of the underlying functionality has changed. I was able to implement it into a relatively fresh version of tbaMUD and get it to compile, work and run with some minor alterations.

Thanks for taking the time to update that!
I had to adjust a few things but it seems to be working
the only issue is it only works on my Implementer but not any of my actual mortal characters. This at least gets me in the ballpark though! Thank you again!

For the most part its working but now I am running into an issue where if a person casts corpse host on a corpse, it lets them take over the corpse, and they can return from that corpse by using the return command, however, if the spell/affect duration ends it crashes.

I had to set tweak a few things to get it to boot up and work on my end.
Two major differences is I used af.type but also add af.bitvector to apply a corpsehost affect for both the character and the zombie
And I eliminated it creating a mob based on the players level, stats, etc and just have a generic level 35 zombie it 'summons' when the corpse host spell is cast.
The issue seems to be from how the aspell interacts with the snippet in handler.c

Code:
ASPELL(spell_corpse_host) {   struct affected_type af;   struct char_data *mob;   if ((obj == NULL) || !IS_CORPSE(obj)) {     send_to_char(ch, "Thats not what you need to be concentrating on.\r\n");     return;       }     send_to_char(ch, "You transfer your life force into the fresh corpse.\r\n\r\n");   mob = read_mobile(MOB_CORPSE_HOST, VIRTUAL);   char_to_room(mob, ch->in_room);   extract_obj(obj);     af.type = SPELL_CORPSE_HOST;     af.duration = 0;     af.modifier = 0;     af.location = APPLY_NONE;     af.bitvector = AFF_CORPSEHOST;   act("$n transfers their life force into the fresh corpse.", TRUE, ch, 0, 0, TO_ROOM);     affect_to_char(mob, &af);   affect_to_char(ch, &af);   ch->desc->character = mob;   mob->desc = ch->desc;   mob->desc->original = ch;   ch->desc = NULL; }


Code:
       /* return corpse host people to their proper bodies */   if (af->type == SPELL_CORPSE_HOST && ch->desc && ch->desc->original) {     command_interpreter(ch, "return");     die(ch, NULL);   }
