instantpvp

On freeshards, if a mob has an instant ability they typically spam it.  Especially if the ability is a DoT or CC of some sort.

 Live Basilisks were not as reliable as they are here, they had a percent chance to Stun and did not perfectly stun, wait for immunity, and stun again.  Here, the pet is so reliable it will ALWAYS stun (will spam if resisted) as long as the player is in range and does not have immunity.  Once the immunity is gone it will stun again.  If the pet has a DoT, the moment it is sent to attack the pet will keep the player perma DoT'd unless otherwise.

Yeah I'm not willing to reactivate my account just to see what the aged basilisk does but I did manage to find it on Argain and it is a red con mob to my level 17 friar and according Camelot Auto-Bestiary they are only level 19-21 http://www.mindkayak.com/bestiary/mob.jsp?mob=813 which means no one has come across a level 48-52 so therefore technically they are not even supposed to exist for us.  Also it did stun but only after one second and not even on the first swing it was like a spell it cast within 1 sec of being agroed then swinged at me.  This is on Argain so not live at all but I still say it is a mob that should not exist out there because it doesn't even exist in live at that level.
