Hi!

Ok so repair cost confuses the frick out of me. I know superior items cost more to repair but I still need answers. In short I want to make a Last wish in a CB.
Yes I can repair with an Ort rune I know, but this will be for a sort of hybrid horker I will have extra gold and want to pick the base wisely in order to waste the less gold and just repair the odd 1-10 durability without breaking the bank.
So here is the question breakdown
Is the repair cost of a 15 superior, 15/15 superior, 15/3 superior the same?
Also is a 14 sup cheaper to repair then a 15 sup? or as soon as it has the superior tag its all the same?

If 15 is cheaper to repair then 15/3 then I will go with 15sup. Same for if 15sup is cheaper then 15/15
if 15/15 is equal then I would go with that since less trips to the repair shop. Dont really care about the 3ar

Also side question how does runeword affect repair cost, is it based on rune values.
How much cheaper would it be to repair a Plain CB lastwish vs a superior CB lastwish?

Any calculators or formulas out there that can help me figure this whole thing out?

Thanks!

No formulas or calculators that I'm aware of.

But superior items costs about 2000% more to repair compared to common items.
Granted, picture is of an armour, but you get the idea.

Interesting!
so what I can see is the plain 15 and the 15/15 pretty much have the same repair cost. But indeed a plain CB would be much cheaper to repair then a superior, that 15% ED might not be all that worth it on the long run.

Edit; Arguably going for 15% durability is a lot more worth it, since it is about same repair cost, but you get 15% more durability points, so repair cost per durability is less

I had issues with repair cost as well in the past. Get a gold barb then all your LW repair cost issues are solved.

A basic gold barb can gain u over 300k in a single travs run under 2min, max it u can get 500k+.

Never worry about gold anymore

TL;DR: Using superior bases in PvM is a bad idea in general. The upsides are miniscule, and the repair costs can be a huge PITA.


Those tiny bonuses (15% ed, 15% imd, 3ar) are insignificant contributors to the superior repair cost, they don't matter. A superior 0/0 (created in a character editor) always costs roughly the same as a superior 15/15 or 15/3.

The only significant contributors to the repair cost are: the superior quality, and the cost factors associated with the base item and the runeword bonuses in the game data files. Lower level base item can have significantly lower superior repair cost for the same runeword. Cheap runewords can also have brutally expensive bonuses, for example the high cold damage of Duress. Examples: Treachery costs a tiny bit more to repair than an Enigma in the same superior base. Duress repair cost is more than 2x Enigma repair cost in the same superior base.

You can check repair costs with a character editor:

• non-superior Colossus Blade Last Wish (perfect roll, 0 durability): 41,856
  
• superior 0/0 Colossus Blade Last Wish (perfect roll, 0 durability): 177,152
  
• superior 15/3 Colossus Blade Last Wish (perfect roll, 0 durability): 179,200
  

The repair cost of a superior CB Last Wish is quite low compared to typical superior repair costs of other runewords. The cost factors associated with its bonuses must be low. For example, superior Gerater Talons Mosaic can shoot up to 4mil+ depending on the +skill automods on it.


The rune values and rune rarity are insignificant factors.


Usually much cheaper, because non-superior runeword items exclude the runeword bonuses from the repair cost calculation. The full repair cost (from zero durability) of a non-superior item is often below 50k, while the superior repair cost can be hundreds of thousands or millions for the exact same runeword in the exact same base (but with superior quality of course).


A couple months ago I did some detective work to figure out how to calculate the repair costs of superior/non-superior body armor, helm, and shield runewords. Be warned: it's a bit complicated!

For weapons, the calculations would be pretty similar, but the enhanced damage calculation would be a bit different, and probably dependent on the 1-handed and 2-handed damage values. (Similarly to how the defense roll and enhanced defense bonuses affect armor repair costs.)
Magic/rare/unique/set items also have their own quirks to their cost calculations that I didn't bother with, but the basic ideas would be the same as in case of armor runeword cost calculations. Figuring these out is waiting for a brave soul.

Here are some better images to demonstrate the differences between superior ED/IMD rolls, and the fact that higher rune rarity+value doesn't necessarily mean higher repair cost:


Mage Plate Enigma (perfect roll)




Dusk Shroud Enigma (perfect roll)




Dusk Shroud Treachery (perfect roll)




Sacred Armor Duress (perfect roll)
