Invaders!
Monday we went to LOTD to knock out some Tombs. A benefit is we check most of them for Destruction. We heard Arsenal was in TOVL and decided to pay a visit (click to embiggen):
We won the battle after disabling the fire trap (to be fair they just arrived as we beat the trap so they must have been pretty far in). Three of our members won purple bags.
Unfortunately when the instance timed out we all got a 30 minute debuff that said we couldn’t join or invade any more Tombs 
( What was that about? Later someone said that Arsenal was still in there despite us purging their instance. I’m guessing they found some sneaky way to remain there after death.
