 * description = Known as the "General of Shavarath", Arraetrikos is the raid boss of The Shroud raid, introduced in Module 6. Arraetrikos is encountered in Phases 4 and 5 of the raid.

He is often nicknamed "Harry" when discussing "Harry Beaters," weapons containing both Silver and Good that will bypass his damage reduction.

Developer Confirmation

 * developer = |source=http://forums.ddo.com/showpost.php?p=4098065&postcount=34|quote= Every Pit Fiend and Horned Devil raid boss' fortification is currently 50% on normal, 65% on hard, and 80% on elite. Epic Velah's fortification is 50%. Epic Lailat's fortification is 80%. Even the Lord of Blades left his heavy fort item at home, and is sitting at 80% (even though he really should have the Improved Fort feat).

If people are working together to reduce fortification, those numbers are able to be significantly lowered or even reduced all the way to zero, and all of the physical DPS goes up.}} }}
