Titarus

As of Warlords Season 3, this guy is easily soloable even in current season honour gear.

Just get a [spell=169372] from Brute's Rise and then bash your way into the cave and clear the nearby trash while taking care to leave a few [npc=80511]s floating around near the boss.

Once the trash is dead, allow your boulder shield to build up to max shielding then kill one of the aforementioned [npc=80511]s for their 100% damage and healing buff.

Pop your cooldowns and melt the boss.

Easiest class skillbook you will ever earn.

To be found in a cave in the Molten Quarry, entrance 58, 70

This guy is really useful for all the raid you're going with. Be sure to check inside that cave whenever you can to see if he's up because he drops a guaranteed (100%) unique item for everyone who is killing it. Each class has it's unique thing to drop. Libram for paladins, sigil for Death Knights and so on, these provide really really awesome buffs to one of your main spells for one hour.

Beware though: you need like 7-8 players to down this beast, including a tank and a healer.

The buffs last for one hour and can only be used in Ashran!
