Step 1: Get a character to level 80.
Step 2: Assure he's in the correct gear.
Step 3: Get a max level to clear to Alg.
Step 4: You on your level 80 enter the room so he will appear neutral before his RP event.
(Here's the tricky part)
Step 5: Have the Max level leave the party... when he does it will register him out of the raid and give him a count down.
Step 6: Now when he has 15 seconds before teleporting out, have him run in and use a hard hitting ability, IMPORTANT that you and the Max Level both hit him at the same time.
IF DONE CORRECTLY THE 120 WILL REDUCE HIS HP TO 1HP WITH THAT HIT, BUT AGAIN YOU MUST BOTH REGISTER A HIT ON HIM AT THE SAME EXACT TIME OR HE HAS A
MECHANIC THAT WILL AUTOWIPE YOU AFTER THE RP EVENT.
Step 7: Now the 120 will get teleported out and you will be alone during the RP event.
Step 8: After the RP end stand at max range and use a ranged ability and 1 shot him.
Step 9: Now you're a "Herald of the Titans" Grats.
I'VE DONE THIS MULTIPLE TIMES AND IT JUST TAKES TIMING. IT MAY WORK THE FIRST TIME OR YOU MAY HAVE TO TRY IT MULTIPLE TIMES.
