[John Adams]

I did a search through the PLs for settimer, which I am sure you looked through as well. Below is the Dark Elf Corruptor script, showing his spawning as setting a 600 second countdown to despawn. Once the 600 seconds expires, EVENT_TIMER pops and removes the timer and the NPC.

# dark elf corruptor shouts before attacking
#

sub EVENT_SPAWN {
  quest::shout("We come for you, fools. Your reign of weakness over the powers of the land comes to an end now!");
  quest::settimer("despawn",600);
}

sub EVENT_TIMER {
  quest::stoptimer("despawn");
  quest::depop();
}

sub EVENT_DEATH {
  quest::stoptimer("despawn");
}

Can you set the settimer("castdelay",10) and then use the EVENT_TIMER to kill the timer, then cast the spell?

stoptimer("castdelay")
castspell($userid,spellid)
