I just finished running Shadowmoon Burial Grounds on Heroic difficulty. I’m not going to write a full guide to each dungeon, because frankly better people than I have already done so, but we did figure something out that works quite well against this boss.
A quick overview of Bonemaw:
He basically has two mechanics that you need to worry about. The first is Body Slam, which will do some damage and knock players off into the water. The second is an Inhale ability, which will suck players into his mouth and cause an instant death. I’ve been told you can run away from it if you have a burst of speed like ability, but the in-game mechanic designed to work around it is to stand in the patches of Necrotic Pitch that Bonemaw shoots on the ground.
The pitch acts like a glue and, although doing some decent damage, will not allow you to be sucked in during inhale.
The simple start is to avoid the ground slam and then stand in the pitch when he begins his inhale.
However a rogue in my guild found a good workaround for this.
If you happen to be too far away from the pitch when the inhale phase starts, just jump down into the water. Swim to the water spouts that are conveniently placed around the boss zone. Once inhale is done swim to the waterspout and you’ll be pushed back into the boss zone.
The downside of this is obviously you’re not doing any damage to the boss during the inhale phase, but you’re also not taking any damage, which might help you healer out a bit.
