Delegation

This is exactly how to do the quest, from start to finish...

While fighting [npc=52558] you loot the [item=70997]s from [object=209033]s which randomly spawn around the edge of the area (note: possible link to the volcano spawns, but those are random as well). Gather three of these and create a [item=70996], which is then used just before he uses [spell=97282]. He has to stand on it almost directly so make sure you're pretty close before using it. Loot the [item=71008] afterwards.

While fighting [npc=52498] you loot the [item=70999]s from [object=209037], three of which spawn when a [npc=52581] is killed. Gather them and create a [item=70998], which is then used on top of the web just before she uses [spell=99052]. Go back up once it's safe and loot your [item=71017].

While fighting [npc=53691] you loot the [item=71000]s from [object=209035]s, one of which spawns when a [npc=53713] is destroyed. Gather three of them and create a [item=71001], which is then used just before he uses [spell=100002]. The spear has to hit the focus so make sure you're close. Once the fire has died down loot the [item=71015].

While fighting [npc=52530] you loot the [item=70994]s from [object=209036]s, one of which spawns when a [npc=53898] egg hatches. Gather three and create a [item=70995], which is then used just before she reaches [spell=99925] (100 energy). It doesn't matter how close you are so just drop it where you're standing at around 90 energy and then loot your [item=71016]. Note that only two of the fragments spawn at a time, and that if you are usually flying around you will have to switch roles (or just have no-one flying at the start) to do this.

A very important note if you want to get Dragonwrath as soon as possible: do NOT kill any of these bosses. You can loot your charged focus then just wipe and move on to the next boss. Also note that if your raid is willing to let you do this, it only takes a few minutes to do the quests in between this one and Time Grows Short as there is no fighting or anything involved, it's just travelling and cutscenes. To make this as quick as possible I'd advise setting your hearthstone to somewhere near Amber Ledge, like [npc=25278] for Horde or [npc=26596] for Alliance.

Once you have all four of the charged foci go to the portal near Beth'tilac and use them. After entering the portal you begin the encounter with Volcanus, which is a three phase fight.

Phase 1 - just interrupt and kill all of the [npc=53793]. You can burn mana and cooldowns to make this easier as phase two starts only when the player on the quest tries to loot the branch.

Phase 2 - [npc=53825] will need to be tanked at the entrance portal. He casts entangling roots which does damage, but only dispel them AFTER he does his stomp. If you dispel them beforehand you will get knocked back an enormous distance and die. Once he does his stomp dispel them as soon as possible. Small treants will spawn periodically and act identically do the transition phase adds on Ragnaros: they must be killed before they reach the treant. Ranged should deal with them. At the end of this phase he becomes friendly and casts [spell=100274] on the player on the quest.

Phase 3 - [npc=53833] will fixate on the player on the quest (who is transformed into a huge tree of life) so tanking will not be an issue. Use ALL DPS cooldowns and burn him down quickly. There are a few spells to avoid, so as always do NOT stand in the fire. Healers have to compete with constant raid damage.

After that just loot the branch. Simple!

I don't know what Blizzard was thinking when they decided not to tell players what they need to do in the quest text. It's not like it's a secret to be discovered or something. Anyone who can get this far into the questline is a competent raider and knows all about wowhead. Zero quest description just seems like an annoying waste of time. Just imagine if they did it for the entire chain.

Special notes:

- There are 3 stages to each item: FRAGMENT, DULL, and CHARGED.
- You keep the FRAGMENTS when you die. They have no duration.
- It takes 3 FRAGMENTS to make a DULL.
- You keep DULL items when you die. The DULL items have a 2 minute duration.
- When you use a DULL item it drops the item at your feet. From then on, it is untargetable and unlootable. If you mess up, you have to get 3 more fragments.
- The CHARGED item spawns after the event happens. You simply loot it like you do a fragment

For Rhyo, the fragments spawn from small dirt mounds around his platform. Generally, they are on the outer most edge. Collect 3, combine them, then stand directly under him when he stomps. The item will be lootable.

For Shannox, the fragments spawn from when the crystal trap is broken. Stand in the spear toss and drop the Dull item. Loot it when done.

For Alysrazor, the fragments spawn from the shells of the young birds. Stand in the center when Alys lands and drop the item. To clarify, you do this when Alysrazor is gaining energy NOT DURING THE TORNADO PHASE! I dropped the item at around 90 Energy and it was fine. Loot when done.

For Beth, the fragments spawn under the drone. You have to go up, place the item, when you go BACK up after the explosion, the charged item will be there. I made this easy by putting a raid marker on top of the item. Made it easy to find it once I went back up.

Good luck, enjoy your stage 1 staff.
