Forge and Befuddle

Very simple achievement. Takes 5 days to complete. Here are the tomtom ways for all the npcs:

/way #85 52.6 75.6 Scout Stronghand
/way #85 54.0 73.4 Grunt Grimful
/way #85 49.2 71.6 Ambassador Dawnsinger
/way #85 48.6 82.6 Branzlit
/way #85 56.4 61.2 Suja

Scout Stronghand patrols around the main road.

In theory it is account wide and can be done in a day if you have 5 inscription alts but its not worth it in my opinion to make them specially for this.

This achievement can be done under 1 hour with 5 alts.

Go to Orgrimmar / Stormwind and learn [skill=773] + cata skill.
Buy Virtuoso Inking Set + 1 Blackfallow Ink + 175 Light Parchment.
Go to uldum and talk to [npc=162419] for legacy uldum.
Go to this spot [npc=48631] and kill some packs and learn [item=65651].
Craft [item=65651] untill 50 cata.
Go to the profession trainer and learn Forged Documents.

Repeat this 5 times with 5 differents NPC around Orgrimmar.

NPC : 1 [npc=46708].
NPC : 2 [npc=17098].
NPC : 3 [npc=44871].
NPC : 4 [npc=44853].
NPC : 5 [npc=14375].

GL :)

Not understanding why you'd need 5 alts... just do it on a single character. Yes that means it takes 5 days, but what's the hurry? I'm not learning inscription on 5 different characters for the sake of a single achievement.
