About Magmaw, he's not easy in monk, really more difficult than with a druid.
Glyph :
- Glyph of enduring healing sphere = because you have a lot of "adds", you can generate a lot of spheres, After the first mangle, walk on this spheres, it's a powerful help.
- Glyph of Fortifying Brew = A better reduction of damages. Use it into the maw during the mangle, when this CD is up.
- Not particula third glyph, you can use Transcendence to go away quickly after the mangle (the boss can't hit you if you're not at the cac). Anyway Touch of Death is useless since he dies at 400k pv.
During the mangle, you need to have your guard up about 8 secs before the end because he does awful damages on end. You can try to keep a few chi to use chi wave while your guard is up, it's better for the heals.
Kill the worms very quickly with Spinning Crane kick, they are the priority.
Maybe you don't know that : During the mangle, if you have enabled the life bar : (interface > names > enemy units), you can observe the bar of the ''head of magmaw'', dps him, he takes 100% more damages, and it's the better way to generate chi to heal yourself.
If you have problems on the trash, use Xuen when the first die. Your tiger takes all the damages. It's better to kill the two at the same time. Moreover, you can always have your guard up before their stun (30 secs CD, the life is beautiful ).
Good luck, Magmaw is a bit difficult.
Atramedes, after him, is a joke.
Chimaeron is terrible (I didn't kill him, it's a headache)
Maloriak is impossible without 90k dps (Yep, we can't dispell remedy)
Now, about BoT Thrash... They are not really easy (the first before Halfus).
Use everything that you've got.
If you want, you can use an Invisibility Potion. And if you kill Halfus, just reset and then, they will dissapear.
Usually, I do Paralisys on a heal, if there's two heals, and I finish the other heal.
Otherwise, If you have just one heal, use paralysis on an other trash.
You can glyph Touch of Death to kill them very quickly (heal first always), and even faster with the Fortifying Brew (unglyphed, obviously) before ToD.
