The Hero Achievement Not Unlocking...?

[Zaefnyr]

I've completed ALL pre-planed, non-notice board quests, as requested by the achievement's details and the achievement has NOT unlocked..
Helped myself from this site, http://dragonsdogma.wikia.com/wiki/The_Hero , and as dragon's dogma's wikia, i dont know why i dont have the achievement..?

You probably are missing one quest which you haven't noticed, like Valmiro's last one or some other obscure thing.

[Zaefnyr]

I'm very sure about every quest,i even remember how valmiro wanted me to carry his baggages to his little boat..
Is there an order i have to complete them in or something alike?

[Blanc]

No, no order. But this achievement isn't buggy, something is missing. Check here too.

Oh god i thought mettle against metal was the golem that blocked the entrace near the witch's house, i wasn't paying much attention to the details of the quests.. thanks for the help!

[Zaefnyr]

Just one more question: if i missed only that quest, can i do only that and not ALL the other sidequests if i'd already done them, on NG+?

[Corlain]

Yes you can, it doesn't matter how many playthroughs you do them in as long as you beat each quest at least once.

[Karathrax]

That depends. If the missed quest is part of a chain of quests that are only available by completing the preceding quests in the chain, then no, you can't just do that one missing quest.
If you're only missing Duchess in Distress, for example, then to get to that one quest you have to repeat the earlier quest in Alienore's quest chain that leads to Duchess in Distress, which is Arousing Suspicion-- and it's only offered if the Arisen talks to Alienore in the castle garden right after Come to Court.

The other big one is Lost in Found, not only because missing it removes access to one area of the game for the entire playthrough, but also closes off access to Witch Hunt, Dragon's Tongue, Mettle on Metal, Talent In Bloom and A Parting Gift.

Personally, I find it annoying that 'Supplier's Demands' and 'Supply and Demand' have such similar names; they are not related.

[Zaefnyr]

I know what you mean, Kara, but i meant as if i only need to do Mettle against metal and can skip doing Dragon's Tongue.. Which i guess i can, since so many people say it's possible.
Thanks for the help, i found the quest i needed to complete.
