Hi,

rust you are doing well.

I have been trying to progress the Dragonheart Charm quest line from Warrior's Guild.
After bringing this charm to the guildmaster he lets me keep it.. and suggests that I seek out a dwarven blacksmith.
The blacksmith in the Dwarven Halls, however, makes no reference to aany special armor.. i checked his inventory and tried talking to him with L5 Trader's Tongue.

Anyone solved this?

Thanks.

I did, so I can assure you the stuff is there.

The warrior guild master actualy sends you to the dwarven KING, not the blacksmith.
The conversation though is marginal, you will find most of the pieces at their place anyway.
The dwarven BLACKSMITH will only come to play AFTER you aquired the breastplate and have the charm/gemyou mentioned in your post. Then the blacksmith will "repair" (enchant, technicaly) the breastplate. The breastplate will be key item to gain the helmet.

Maybe I misinterpreted .. the guild master noted that he learned abt he armor from his master who in turn tricked some dwarf into revealing it..Any case the blacksmith too directed me to the king.. I was supposed to inform him abt the underground mining conspiracy which I did.. but again nothing happens

I am also attempting to solve the treasure map quest.. I will put in couple of hours and spoil the game on game banshee if nothing yields.

The only thing supposed to happen at the king he noticing you wearing piece pof the dragon armor, and thus giving you a conversation option what other pieces exist.
But even w/o this useless conversation option the set pieces will be at their places, no relation to anything (and if you get any of them too early, they will be weakas a kitten).

As the Divinity-series is famous for its bugs, I hope you won't waste your time by not preparing by a walkthrough though. You should be fine, unless you entered that tomb which you shouldn't have had.
If you did, don't mind it too much though, the random equiipment isn't that bad either. My character ended up with the Larian Armor, and a lot of the dragon set pieces, but also some random rings, amulet, leggings, and boots (some of them has unique names, like Boots of the Vampire). Spent a ton of time rerolling each, but what you need is just some resistances, and then as much HP as the random gives.
