how do you get past the rubble to get into the adamantimium forge?

[Dragnier]

If you are taking about the rubble in the south end of the map, the beasts can clear it for you. You must ask them to continue working and they will clear the rubble. After that the Skarjal will betray you, but the beasts will join you against them. You will save the beasts and also gain access to the forge.

You will need speak with animals or animal handle for that

If you are in the south point of the map there are some dwarves led by Herdmaster Skarjall who is abusing a pair of Deep Rothe. He asks for your help by hitting the beasts so they will work harder and finish removing the rubble.
The beasts are tired but by using Speak with Animals or Animal Handle you can persuade them to keep working and finish clearing the rubble.
After this Skarjall will betray you (it was his intention all along) but you will fight him together with the beasts. When you win you can proceed past the rubble to reach the forge, and the beasts will be saved.
If the beasts are already dead maybe you attacked the dwarves before speaking with the beasts, which will force all of them to attack you. In order to clear the rubble you need to convince the beasts first before fighting the dwarves.

Two smokepowder bombs from derryth or a barrel of smokepowder. But if you leave grymforge, the story progresses and all duergars are gone. So you have to buy / steal those bombs before you sail to grymforge.

The alternative is, to get the runepowder bomb from Philomeen in grymforge, up the sloap behind the slimes you can fight. But the explosion radius is mostly too big and you will kill everyone in the process.

You don't have to get them to clear the rubble first. You can convince the beasts to attack the dwarves, which will trigger a fight with the dwarves. And provided one of them survives, they can clear the rubble afterwards for you.

Or, of course, you can use blast damage.

IIRC, Eldritch Blast will clear it. Just find a good source of Force damage, like EB or explosives.
