My current thinking is to use on an item with a bad quad roll (legendary) or triple roll (epic) until you get a speed hit. I would think reaction banner for accessories and stoneskin, speed, relentless sets for artifacts. 

I would consider this an end game item, as most of us sell items that roll poorly well before the bad quad roll. So these will be like high end glyphs requiring annoying failures until the desired outcome is achieved. 

I have not used any yet, I would suggest most should be just saving them at this point.

I pretty much echo Trips on this. Thing is, I won't have any bad triple or quad rolls, because I'd never get that far on rolls before stopping :/

My personal plan is to save them until I find a better use, but my hypothesis is that I'll use them on lego speed set items to reroll and hope for a speed substat, or, potentially, to use on a speed set item that triple or quad rolled on a "good" substat and hope for it to reroll as speed instead.

Yes, it's strange to say but I do forsee myself rolling for quads on specific items in the near future regardless of the current stats. 

I am certain on using on +16 only, just not certain on which items yet.

Will the ore count against our storage limits for other items?

No, it's just a token that you can use, I doubt there's a limit to how many you can hold, but even if there were, I can virtually guarantee you'd never reach it unless you were an uber-whale.

So, I've thought about this some more, and decided to bite the bullet and use them on unrolled lego speed set top-row items.

I don't have the resources to be able to afford to roll useless items to 12, let alone 16, just to hope for a triple roll or quad roll, and then use chaos ore and likely get a useless item.

I think I'm better off just using them on top-row lego items that missed speed substat, because of how low the probability is to get one of those to begin with.

hmm, valid strategy...rolling an item up tp 8 is manageable for almost all items.....so perhaps you use your speed items with no speed, roll them up to 8 and use the ore on those who already have a double roll?

Perhaps concentrate on weapons and shields as their range of substats are lower?

If you roll up the items to 8 before using the ore, your chances are 12,5 % with weapons and shields to hit speed on the double rolled substat. If you use *pure* items, your chances to get a double roll on speed with the first two rolls are less than that (6.25%). Naturally this amplifies with rolling them up to 12. The chances to get the triple stat on speed is stil 12,5 %...but rolling them afterwards only has a 1,56 % chance. 

If I didn't make a calculation error, it would be best to use ore on speed weapons or shields level 12 with a triple roll. 

That would be the sweet point for me regarding costs to level up items and chances to get speed substat.

9Pick a side matrim! Can't like both strategies lol.  

I think using on top row unrolled is a horrible waste. I just need to look at my 1299 artifacts in storage as evidence, my hoarding problem is obviously no
