just a fast question . am making a deadra sword i have an enchanted blacksmith rob and the ring and Gauntlet and necklace of major blacksmith
i bought the blacksmith elixir and improved the sword within the 30 sec
but the result was the same for the sward with or without the elixir .

the chances is that i did something wrong maybe ? or do i stand correct ?

the 30 secs wears off really quickly. basically don't chug it until you are ready to improve the weapon and then very quickly try it.

I have done this myself and it isn't the fact of the potion wearing off. On my first character I had a set of items with smithing and smithing potions. I experimented and found there is a kind of cap to using enchantments to upgrade armor and weapons. I tried it with just the items and then with the potion and items, it turned out the same and the potion had not timed out. Only way to get past the % cap is too basically use the restoration potion exploit.

ok so i forgot to say that i have my smith skill at 100. so without using any exploits we can say that the deadra sward cap is at 110 ? because

am sure it was within the 30 sec i tested and it cant be raised above that

If you can forge a daedric weapon, you by definition already have high enough skill (and the required perks) to make it legendary. I don't see how any bonus to smithing would help; you can't go better than legendary, which you get just by virtue of having 100 skill and the perk. Those potions and enchantments are for folks who want to make (non daedric) legendary weapons and do not yet have 100 smithing skill, or for when you want to enhance a weapon / armor type you do not have the perk for (say to take a found glass sword and improve it, without the glass perk- without a skill above 100, you could not make it legendary).

If you want your legendary daedric sword to do more damage, you need to enhance the USER, not the sword. For example, my mercinary has boots, gauntlets, ring, and necklace that increase the damage he does with 2 handed weapons, and multiple perks that do the same thing. He does something like 140 damage with his flawless ebony greatsword, but a lot of that comes from his (magically enhance) skill, not the weapon. If he gives the same weapon to his follower (who only has 1 handed training, not two handed) its a lot less effective. It aslo drops down a lot in damage when I swap out my gear to wear all my alchemy enhancing bling... or all my smithing bling!

Try again ? There's no cap for how much you can improve; but all the percentages and numbers are floating point numbers that get rounded...

There's an equation you can use to check. Its probably on uesp.

AFAIK there is no cap on weapon damage, I could be wrong. If you are not sure if your potion was active, as soon as you exit the crafting screen, hit B (or whatever) immediately and go to the Active Effects menu. It should be listed under Fortify Smithing still.

"Legendary" covers a big range. You can push it very high if you try. With his usual gear, the weapon of my thief comes up at 94, that is an unenchanted Blades Sword. With his usual gear, my Orc comes up at 397, with an unenchanted Dwarven Warhammer. The Smithing skill is the same, the weapon skill is 4 points different, what makes the big difference is the Orc can enchant gear! If he is naked it drops to 147.

Ah, double checking UESP, it does seam you get .1 damage per point in smithing when you go past Legendary. So if you have (enhanced) skill over 91 and have the perk (as is obviously the case here) its gonna be higher than the baseline for a legendary daedric weapon.
So yeah, the potion should be bumping up damage by (potion bonus)/10 points.

edit - I've noticed that the "active effect" list seems to not always reflect what you would expect. For example, it often shows me getting "Bonus Two Hand Damage" from a ring... and then again the same bonus, from a ring, on the next line. Meanwhile it fails to list the bonus from my boots.
Whether that's just a glitch in the listing or actually reflects the bonus I get, I don't know.

That would be a programming glitch on the display if you ask me.

ok yes i have all the smith perks . i bought another elixir and i will try again and post screen ill be back shortly

well i was wrong again . ok i got it this time but still with the elixir its 110 without it its 90 so the improvement is not
50% the screen of the effect was taken after the improvment

It's a glitch. I had boots and gloves with the same fortify one handed, whichever equipped first showed up twice. Made more gloves with an extra 1% effect, both items displayed correctly.
OT, I find the potions are really useful if you don't have the corresponding perk, not so much with materials you have the perks for.

There is no cap.

[Edit] Whoops, I misread, there is definitely a cap for that.

Blacksmithing bonuses do nothing for crafting, only upgrading via table or grinder.

True, any enchant or potion adds to skills and perks.
No cap on weapon damage, and no cap on armor except the 570 cap on total armor level, however gear with armor level 1000 might be useful on an follower with lower armor level.

Main issue is that unlike Morrowind and Oblivion time passes in the smithing and enchanting interfaces. So you drink potion and access the grindstone, make sure to have all the materials you need, it might be smart to check first as it's not always intuitive.

Now you improve items as fast as possible, you can not do much wrong, don't have a lots of trade weapons in inventory as it might confuse.
Then you are done it might be smart to check active effect it would typically show fortify smithing 50 points and 6 seconds left.

My smithing is at 100 and I use clothes, rings, necklaces and gloves, to boost my grindstone and bench results. Once I have a few things I want enhanced I'll still use a potion and it does indeed boost the stats beyond what I could have done without the potion (I've checked and double checked.) I'm on Xbox so I dunno if it's the same on every platform.
