When I was playing with soulbinders, castspell didn't work, as you described, so I used selfcast which, seemed to work OK. (Been a while since I played with this though). IIRC I had the same problem with translocators, I had to use selfcast rather than castspell.
Code:
sub EVENT_SAY {
if ($text=~/Hail/i){quest::say("Greetings $name . When a hero of our world is slain. their soul returns to the place it was last bound and the body is reincarnated. As a member of the Order of Eternity. it is my duty to [bind your soul] to this location if that is your wish."); }
if ($text=~/bind my soul/i){quest::say("Very well. You will return to this spot when you die.");
quest::selfcast(2049); }
}
