mind sound a bit stupid, but get a lv 70 paladin to boost you through, my main is a holy paladin and every alt i boosted through scholo and strath goes really fast, the aoe damage ticks for loads when you got a paladin in T6 and the exp is quite a nice boost if you cba to level questing. Ofc im 5 boxing now so with my shamans I'd have to do it myself (so i prolly won't .... scholo has too much fear, strath too many enrage and cleave mobs and in cloth gear that won't be smart )
edit: to reply to the above person run back from where you entered the main entrance, when you arrive there go to the right gate (you went left to go scarlet) open that (double gate) kill the skellies there then go to the big opening right in front of you, you should now see the boss that drops the keys and 3 packs of skellies (and the chapel) that's the side entrance also known as undead site, you can kill the boss (not really needed) but you'll have to kill the skeletons guarding the gate on your right (aka the door that leads outside) kill them open up and your out.
unfortunatly you can't go out of the main entrance so you'll have to go out side entrance, reset and run back to the main entrance
