Pick an araxxor that you are strong against. Watch the leg tips (red=melee, green=range, blue=magic). Exit to lobby if the wrong type spawns. You will lose your 200k if you paid the instance. Make it a habit to right click "walk here" to avoid the cleave. Sometimes araxxor's hitbox is too big and left-clicking makes you stay on him. This is important in path 2 when araxxor is dropping the acid on the rock. If path 1 is one of the two options, I would advise burning that web. You won't get overwhelmed by minions in phase 3. You can walk a little bit into path 1 to trigger phase 2 and stay in the the phase 1 area if you feel you need more room to move. The exploding acidic spider spawn is one of the specials if path 2 is open. If you've counted five autoattacks and haven't seen the web, cocoon, cleave, or egg spawn, get ready to run away. Look for a range attack that lands on a random location that turns into a green puddle. Get away from that. If you decide to lure the highly acidic spiders into araxxor in phase 3, make sure you give yourself and araxxor room. You will get stunned and take 2000 damage if araxxor gets stuck and dances on top of you too long. You can tank the darkness from path 3 in phase 3 and focus on damage if you feel comfortable enough. Devotion and debilitate are great abilities to reduce damage, espcially on araxxi. Higher settings let you see some of the boss mechanics easier (acidic spider spawning and light in darkness).
