Is the "Complete Arsenal" achievement broken?

[☠An Actual Skeleton☠]

I have collected all weapons in the game according to the possible drops, location secrets and upgraded forms, but the achievement didn't trigger. Is it because there are more weapons to be added, or is it busted?

[MegaZX]

Kinda frustrating, I'm locked out of this achievement and all spells and an ending due to bugs.

A common fix is to evolve the shining blade BACK into the Shadow Blade, and then perhaps even into shining blade again.

Apparently the flag for owning the shadowblade doesn't trigger properly on pickup, once you evolve back into it it triggers.

The obsidian sword and shield that evolve into each other, cycle that a few times too.

Those two things have consistently helped.

[Leogrim]

Did already both...seems like I am missing one or two secretly hidden weapons. Not sure which.

[Leogrim]

Let me list what I have and tell me if you can think of one that escaped me:
Axe of harming, Battle axe, Blade of Jusztina, Blade of Ophelia, Blessed Wind, Brittle Arming Sword, corrupted Dagger,cursed blade, dark greatsword, dark rapier, double crossbow, elfen bow, elfen longsword, fire sword, fishing spear, golden kopesh, golden sicklem, halberd, heritage sword, ice sickle, iron torch, jailors candle, jotunn slayer, limbo, lucid blade, lyrian greatsword, marauder black flail. moonlight, obsidian cursebrand (changed it and back a couple times), poison claw, privateer musket, ritual dagger, saint ishii, shadow blade (changed and back again), silver rapier, skeleton axe, steel club. steel lance, steel needle, steel spear, sucsarian dagger, sucsarian spear, twisted staff, vampire hunter sword, wand of power, wolfram greatsword, wooden shield and I had the death scythe and the hammer of the knight at some point equipped (but lost due to death quest and knight quest)

In the Labyrinth of Ash. behind a ? door, there is a seemingly endless tunnel, a pillar with blue text holds the solution.

NNSNSSNSNN

Loop around the tunnels in those directions, it'll make a sound if you go wrong - keep going until the pillar breaks.

[Thorolf]

Is it possible that you need Hammer of Cruelty and the Death Scythe, because than this achivment is mega missable

[Leogrim]

Half an hour later and I can't find that ? door. No wonder I missed that weapon.

[Leogrim]

Found it...didn't trigger the achievement. Time to re-equip everything to see if that triggers stuff

[Thorolf]

keep us updated, I'll look at ending E if it gives me something

[Leogrim]

Re-equipped everything and had it like physically out and didn't do stuff. I probably try changing the obsidian weapons some more and the shadow blade.

[Thorolf]

if the achivment is missble because of the two weapons, a new game + mode becomes from a nice to have a reduction of annoiance

[Leogrim]

Got it. I had to make the shadow blade again into the shining blade (I like the shadow blade more due to being a pure shadow weapon and having status immunity. I already had it once shining and back again)

You only need to have had scythe and hammer at some point. Not in inventory at point of unlock.
