I grepped HELPER in my local copy of the code base this (for me) morning. In mobact.c I found this.
Code:
/* Aggressive Mobs */
if (!MOB_FLAGGED(ch, MOB_HELPER) && (!AFF_FLAGGED(ch, AFF_BLIND) || !AFF_FLAGGED(ch, AFF_CHARM))) {
found = FALSE;
for (vict = world[IN_ROOM(ch)].people; vict && !found; vict = vict->next_in_room) {
if (IS_NPC(vict) || !CAN_SEE(ch, vict) || PRF_FLAGGED(vict, PRF_NOHASSLE))
continue;
if (MOB_FLAGGED(ch, MOB_WIMPY) && AWAKE(vict))
continue;
if (MOB_FLAGGED(ch, MOB_AGGRESSIVE ) ||
(MOB_FLAGGED(ch, MOB_AGGR_EVIL ) && IS_EVIL(vict)) ||
(MOB_FLAGGED(ch, MOB_AGGR_NEUTRAL) && IS_NEUTRAL(vict)) ||
(MOB_FLAGGED(ch, MOB_AGGR_GOOD ) && IS_GOOD(vict))) {
/* Can a master successfully control the charmed monster? */
if (aggressive_mob_on_a_leash(ch, ch->master, vict))
continue;
hit(ch, vict, TYPE_UNDEFINED);
found = TRUE;
}
}
}
So yes, the HELPER flag does override AGGR. That explains the behaviour of the dracolich when the HELPER flag is set.
