Guild Wars 2

Okay I went Arah Exp P4 with my friends to get Dungeon Master title. We did pretty well until Simin, took about 2-3 hrs for Simin. Then we went for the last boss (Bloodstone Shard) and we failed on our first try. After that, we went back for him again but it was gone. We couldn’t see it on the altar (we were like ‘omg don’t tell me it’s bugged’).
We tried to explore all maps, clearing events, relog, and almost give up.. Then I tried to suicide on the altar with Dagger Storm and I saw Bloodstone Shard HP bar slowly decreased. I tried to hit this invincible shard on the altar with daggers and it worked! We used AoE and melee on the altar and finally we defeated it lol

For every players who get this kind of bug at the last boss, just kill the boss by using AoE and melee around the altar. Hope Anet going to fix it soon..

Happens frequently, its bad because you cant loot the stone if it bugs.

You still can get loots from the boss =)

Are you sure? I was unable to loot it when it bugged last time.

I think the trick is not to fail on your first try.
I wasnt even aware it was possible to beat simin and have trouble with the shard. To be honest. Unless they have changed the shard drastically recently.
We killed him the exact same way we did melandru, AKA standing completely still auto-attacking him to death over the course of a minute. two people went down to the wraiths, and then claimed the shard was invisible to them, but they could still damage it.

Yeah I got loots from the boss (a bag and some blue). I’m not sure about that, but it will not bugged if you kill it on your first try. If you failed, it will become invincible and some people will get confused because you can’t see the boss but the mission (top right corner) tell us to ‘Search Bloodstone Shard’ and ‘Clear undead around the altar’. We tried to kill wraiths (the only undead around the altar) but didn’t work.
