From Allakhazam, referring to the Corrupt Treants:

They appear about 30 sec into the fight, and start moving in around 1 min into the fight. Until they start moving they can't be targeted. I've herd rumors that if you can kill Deyid before they start moving they despawn. I can attest that once they start moving they don't care if Deyid is up or not. They hit hard and fast, and killed every caster quick. My suggestion is have the casters up close to the melee to give the raid a few more seconds to kill deyid.

It sounds like they'd need to start as untargetable, then after ~30 seconds, they should respawn as targetable Corrupt Treants & start moving in (very slowly I would assume). I think should do the trick:

#Deyid_the_Twisted.pl:

sub EVENT_SPAWN {
    quest::setnexthpevent(61);
    quest::signal(204069);     # Tell any targetable treants still alive to depop after Deyid respawns (18 minutes)
}

#During the fight he summons a ring of Corrupt Treants ID 204068 in PEQ
# By the time you kill deyid they are upon you and attacking you.
#when Deyid Dies you have succeeded, you are not required to kill the spawns.
sub EVENT_HP {

    if ($hpevent == 61) {
    quest::spawn2(204068,0,0,922,1028,280);
    quest::spawn2(204068,0,0,947,1117,200);
    quest::spawn2(204068,0,0,1031,1164,276);
    quest::spawn2(204068,0,0,1121,1154,277);
    quest::spawn2(204068,0,0,1206,1067,280);
    quest::spawn2(204068,0,0,1237,887,272);
    quest::settimer(1,30)     # Timer to spawn targetable treants 30 seconds after untargetables are spawned
    }  

sub EVENT_TIMER {
	if ($timer == 1) {
		quest::signal(204068);	# Despawn untargetable treants
		# Spawn the targetable treants
		quest::spawn2(204069,0,0,922,1028,280);
		quest::spawn2(204069,0,0,947,1117,200);
		quest::spawn2(204069,0,0,1031,1164,276);
		quest::spawn2(204069,0,0,1121,1154,277);
		quest::spawn2(204069,0,0,1206,1067,280);
		quest::spawn2(204069,0,0,1237,887,272);
	}
}

sub EVENT_DEATH {
    quest::emote("An eerie silence settles onto the forest as Deyid the Twisted slumps over, defeated");
    quest::signalwith(204047, 5, 1);    # Send signal # 5 to Seilaen 1 second after death
    quest::stoptimer(1);     # Prevent treants from respawning as targetable if killed quickly
    quest::signal(204068);     # If Deyid is dead before the targetable treants have spawned, tell them to depop
}

Corrupt Treant (untargetable), ID 204068:

sub EVENT_SIGNAL {
	if ($signal == 0) {quest::depop();}	# Depop all at once, instead of one at a time with quest::depopall()
}

Corrupt Treant (targetable), ID 204069 (I assume):

sub EVENT_SPAWN {
	quest::moveto(1011,1081,274);	# Start walking to Deyid's spawn point, will probably require a very slow walk speed for dramatic effect
}

sub EVENT_SIGNAL {
	if ($signal == 0) {quest::depop();}	# Depop all at once, instead of one at a time with quest::depopall()
}
