Lets talk about Stillmaker, Durge’s other canon blade
Okay, so we already know that Durge had the Bloodthirst dagger which was created from Bhaal’s own blood and carried by his chosen.
But there is another dagger in the game you can find that also canonically belonged to Durge, Stillmaker.
We see Stillmaker portrayed in Dark Urge’s official artwork, and it’s also Durge’s blade in Idle Champions, as you can see.
I’ve noticed that Stillmaker matches Bloodthirst in design, but it is conspicuously green, as opposed to every other Bhaalian weapon I’ve seen which are red.
You know who else’s canon weapon has the same green coloring? Gortash. And who is the color green associated with? Bane. Stillmaker looks like it was made in the same design to Gortash’s crossbow.
I posit then, that being close to one another as they were, Gortash either made or commissioned Stillmaker to match with Bloodthirst and gifted it to Durge. It’s far more his style in looks, and I feel it’s something he would have done as he describes Durge as his nearest and dearest, and we know they worked very closely together and admired one another.
It truly makes my Durgetash heart flutter!
EDIT: Here is a close up of the weapons together in game!
EDIT #2: We were discussing on discord yesterday, Orin would have of course kept the Bloodthirst blade after dispatching Durge because it’s made of Bhaal’s blood and carried by his Chosen, but she would not have wanted some sugary gift from her sibling’s Ex and probably tossed it away and Dolor ended up with it, and that’s how it ended up in his stash.
EDIT #3: @arikandkade made an EXCELLENT addition to this theory and I’m adding it because it’s just such great information, thank you so much for this info!
