Did everyone try using the "DeathScriptAbaz"? Like Kish mentions, the quote is for Sendai's death script only. The variables for the other five are mentioned at the end:
DeathScriptAbaz
DeathScriptGrom
DeathScriptIlla
DeathScriptSare
DeathScriptSend
DeathScriptYaga
So, if Jendaddy's area code for Abazigal's lair is right, then it would probably look something like this:
CLUAConsole:SetGlobal("DeathScriptAbaz","AR6005",0)
Hopefully this will work, but...like Kish mentions, the death codes may not even be the same. If it doesn't work, then hopefully someone will know what the death code is for Abazigal in his lair, and post the info or other fix.
Or even better this bug will get fixed in a newer version?
