""But the summoning of Gahz'rilla is a well-kept secret of the trolls. To face him, you must first wrest the secret from them.""

Head over to the Hinterlands and find Qiaga the Keeper (https://vanillawowdb.com/?npc=7996 https://vanillawowdb.com/?npc=7996), she should drop a Sacred Mallet (https://vanillawowdb.com/?item=9241 https://vanillawowdb.com/?item=9241).

Take the mallet to the Jintha'Alor altar located at 59, 77. When used on the altar you'll end up with the Mallet of Zul'Farrak (https://vanillawowdb.com/?item=9240 https://vanillawowdb.com/?item=9240).

Use that to ring the gong at the end of Zul'Farrak. This will summon Gahz'rilla. Good luck!

Once you are in Zul'Farrak, you can find Gahz'rilla's room by heading left when you can. His room has a large pool with a gong at one end. Before you summon him, take time to clear out some of the mobs in the room, particularly the patrols. There are single patrols as well as multiples, including at least one trio of two hunters and basilisk. Take special note of the mobs in the corners, as they can be hard to spot. You don't have to get rid of them if you don't need/want them, but you need to be aware that they are there. Also watch for patrols that come from the adjoining hallways. You likely took out the patrols from one of the hallways on your way in, but the narrow hall on the east side of the room has one or two mobs that patrol into the big room. Their patrol route is long, so you might not see them unless you know to wait for them.

Hydromancer Velratha is also in this room, and is worth taking down even if you don't have the Tiara From The Deep quest. She is a bit tougher than the usual mobs and would be a nasty add if you don't take care of her before you summon Gahz'rilla.

If you don't want to clear the entire room, you need to take out Velratha and all patrols, then clear the static mobs closest to the pool. Depending on how long you take, watch the hallways for the patrols to respawn. They often come right up to the pool, and that will almost surely make for a wipe.

Once you are ready, have a party member with the enchanted mallet use the gong while everyone else stands away from the pool. The gong ringer in your party should also beat a hasty retreat as soon as they finish with the gong. Gahz'rilla will exit the pool to the north, where the steps are. He will pretty much hang around this area unless you attack him or get too close. Once he's at the stairs, jump in the gong end of the pool and pull him to you.

Gahz'rilla is a level 46 elite, but that level is deceptive. 46 is only a level or two higher than the general mobs in the rest of the instance, but he is much more difficult than that. He has a frostbolt spell, a lot of health and a very nasty pop-up attack. His pop-up attack launches you high into the air, which means a lot of damage from the fall. This attack is not targetted and hits everyone who is close enough. Mages and priests (who are way too close if they get hit by this attack...) can use Slow Fall/Levitate to avoid damage, but everyone else will have to take their knocks. If you are fighting in the pool, you will hopefully land in the water, taking no damage. If you fall on land, you will lose around 20%-25% of your max health (not current health). Have a potion ready just in case, then jump back in the pool and move towards the middle. If you can avoid the pop-up attack, you'll find that he is not too tough to take down.

For those of you who missed this quest at first, or earlier scoffed at the Carrot on a Stick reward, and are doing this at higher levels, you won't need a full five man group to do this. My 55 shaman and a 51 shaman paired up and we were able to go from the start of ZF to beating Gahz'rilla with no problems.

Jintha'Alor is a very boring and bland area and it is pretty hard to find a group willing to escort you to the top to get your mallet enchanted. You can naked corpse run (or feign death/vanish) your way up there and if timed correctly (the Priestess enters the cave every now and then), you can approach the altar and charge your mallet without waking the guy sleeping there, then hearth out.

Easy way to battle Gah'Zrilla:

Step 1: If you're entering his area via the narrow pass, clear the mobs in front of the pass or patrolling in front of it. NO need to clear the mobs adjacent to the path.
Step2: Make sure to kill the named troll priestess that paths around the pool. She fears people so get her as far in to the pass as possible before dps'ing her.
Step 3: The tank has to go straigh to the edge of the pool and pull the mobs near the gong to him and run back to the group waiting for him at the entrance of the pass..Clear that group.
Step 4: Whoever has the mallet, go stright to the edge of the pool and then turn left to the gong (This is to not aggro the other mobs) and hit the gong and run back the same way to the group.
Step 5: The tank goes straigh to the pool and pulls Gah'Zrilla to him and when the boss is closing in on him, he runs back to the group.
Step 6: Tank the boss in such a way that only his head is inside the pass but the rest of his body is outside. This way only the tank will get punted. If and when the tank gets punted, he will land on top of the arch above the entrance and can jump down on the boss. To reduce damage, when the tank gets punted, shift to berserker stance and intercept him and switch to def stance.
Step 7: Kill him.

This way, you don't have to clear the entire room, just enough to summon the boss.

Cheers.

For some reason, my level 44 Draenei shaman got 'not eligible' when my party members tried to share this one.

After the instance I went to where you get this and discovered the reason I could not get the share was that I had the previous step in my log. I just kept missing noticing that during the run...

So, if you can't get the quest, look to see if you have the step before it in your log. :)

This quest counts for the https://vanillawowdb.com/?achievement=1680 Loremaster of Kalimdor achievement.

As of patch 3.0.8, you no longer require the Mallet to hit the gong to summon Gahz'rilla. You can just walk up and use the gong.

Does NOT reduce rep with Bloodsail Buccanneers!

Neither do https://vanillawowdb.com/?quest=2768 https://vanillawowdb.com/?quest=2768 and https://vanillawowdb.com/?quest=2865 https://vanillawowdb.com/?quest=2865 and https://vanillawowdb.com/?quest=3042 https://vanillawowdb.com/?quest=3042
