How to spend your Bonus Rolls

We make features that we want to use ourselves – and I always found myself asking, “What bosses do I save my bonus rolls for?” This feature became an instant hit – apparently a lot of other people also wanted that question answered. Even a few Blizzard folks are using it (and tweeting about it!)


Here’s a demo video of the bonus roll feature that I made for patch 5.4. Everyone is probably killing more than the first few bosses now, but you’ll get the idea :)

How bonus rolls work:

There’s roughly a 15% chance your bonus roll gives you loot. We calculate the % chance you get an upgrade like this: we take number of upgrades divided by possible items, multiplied by 15%. So let’s say there are 4 drops I could get from a boss, and all 4 are upgrades because my gear is scrub. I’d have a 15% chance to get an upgrade. Now, let’s say only 2 of the 4 items are upgrades, I’d have a 7.5% chance of getting an upgrade, and a 7.5% chance of getting an item I don’t need. I’d also have an 85% chance of smashing my face on the keyboard if my luck is bad ;)

Let Mr. Robot help you with your Bonus Rolls!

Unfortunately, he can’t hack the boss drops yet to guarantee you’ll get something. But he CAN help you optimize the bonus rolls. Let’s take a look at the information you can get in the “Find Upgrades” feature. I used screenshots for the new Throne of Thunder raid, but any 5.0 raid works just the same :)


Select the zone where you want to spend your Mogu Runes of Fate (bonus rolls). You can choose LFR, Normal and Heroic. Below is what it looks like for an LFR Queue.



How to make a decision:

You have a few things to help you decide:

  • The chance you’ll get an upgrade: remember, 15% chance means every item is an upgrade. If you win an item from a boss with a 15% chance, you will NOT get a duplicate item or a downgrade! If this is your thing, sort by ‘best chance.’
  • The average score of upgrades: some bosses will have 2 HUGE upgrades for you, and 2 very MINOR upgrades. Other bosses will have 4 PRETTY GOOD upgrades. Mr. Robot averages these together to help you decide.
  • The biggest upgrade score: If you’re looking for that HUGE upgrade, this might be the deciding factor for you. It might require a little restraint if the chance to win it is low, but that’s what the mute button on your mic is for, amirite?!

Mr. Robot – Your Bonus Roll BFF:

Mr. Robot is here to help. He’ll provide you with all of the information you need to make a decision. He doesn’t claim the decision will be easy, but with help you can make decisions that maximize your upgrades and minimize the chance you get duplicate items. Unless of course, you want to take the big gamble on a huge upgrade with bad chances. He’ll let you do that, and he’ll be cheering you on too!

    Thanks for the great post, this helps understand not only what the numbers mean, but how to use them to make decisions. Appreciated!

    • Hemming

      And I’m going for Horridon every time in this scenario. I guess I’m a gambler and trinkets are always fun to get.

      • zoopercat

        Glad you like it :) It’s fun to make tools that I know I would use, and find out that other people want them too :)

    Promoting premium only features of Askmrrobot, Mr Bashiok? do you get a share of that $12 a year?

    • Vincent Polite

      Strangely, my reply-to got posted as a guest above. My comment @facebook-100000477555222:disqus and Bashiok was intended for here.

  • friendfriar

    Looks like this tool was built with the assumption that you can’t win loot that is dropped from multiple bosses (like the Greatsword of Frozen Hells) via a bonus roll. Is this correct?

    • Vincent Polite

      Not sure, friend friar – at one point I thought it was including those multi-boss drops in the list – at least it was for my rogue. I’m not sure what is available for my other classes that I could validate against, though.

        Ummmm this Bonus loot roll is whack….one of our priest won’t Heroic WF BIS trinket for all CASTERS last week, and this week she used her coin and received a Heroic Version of the same item…Blizzards first needs to not give loot if that person already has it ON. its that hard for them to write a script to scan the person rolling to make sure he/she doesn’t have it. My poor priest has 2 of the same Chest and Bracers…i believe Blizz should give a refund if you use ur coin and get the same shit you already have!!! my point is if the boss is on farm in ur guild don’t WASTE ur coin.

        • Vincent

          J, you might want to post this in an official Blizzard forum. There are all sorts of reasons why what you are suggesting won’t fly. But the AskMrRobot team has nothing to do with any of that. :)

          That, and your comment has nothing to do with the thread.

        • zoopercat

          That’s why we calculate your chances of winning an upgrade. For some bosses, you might only be able to use 1 of the 5 items that drop, so we reflect that in the % chance to win, hoping it helps people make a decision on what bosses to roll on.

    @Patrick, I seriously don’t think Bashiok has a horse in this race except to promote a useful tool. For me, personally – it was a no brainer to use and pay for the premium features. There’s nothing else out there like this (that I’m aware of?). Sure you can cobble together the information yourself, and I am also willing to concede that some of the optimizations for speed create a disconnect between what the theorycrafters and other tools might say vs. what the robot recommends.

    But what I have noticed since using the tool is that any issues with min/maxing are off by such a small amount that the upside completely trumps the downside.

    The speed through which I can reforge, look for upgrades, and ask those questions like, “What should I spend my valor on?” or “What bosses should I use my bonus roll on” or the slightly convoluted but totally worth it feature, “What is the best set of items I can create from within my bags/bank?” all before that bonus roll timer expires…?

    Yeah, the Robot overlord can have my $.50/month. No questions asked. My time is worth that and then some.

  • wowtipper

    it’s obvious who you want to use your bonus roll on what boss. If a boss drops a weapon you want, use your bonus roll, if you want a tier item, use a bonus roll. But either way I can’t win crap with bonus roll not with regular roll so doesn’t matter. Just going there to collect my 29g per boss and paying 150g in repair bills from one wing in LFR

  • Oberon – TW Hellscream

    I’ve been a great fan of the Mr. Robot tool ever since it came out. Although sometimes I like to try out my own reforging recipes, to tailor to my own play style. But Mr. Robot has always been spot on to direct me in the right direction.

    However, as of late on the Asian servers (Taiwan) we have been getting higher item level gear for 25man raids. For instance 530 in Throne of Thunder, and 536(or535?) on lightning forged items. This has completely thrown off the usefulness of this terrific tool, and left us Asian servers back to large amount of trial and error. Is there anyway that you can improve on this? For instance of custom iLvL’s? or area to input the gear stats manually?

  • markshp

    It is becomming too much premium nonsense

    • infr

      oh relax, it’s one dollar a month. and even if your situation is such that you cannot afford it, you can still do all these calculations yourself using and use Mr. Robot’s free features.

      So strange when people get bitter over a small free for an optional service after being provided (and continuing to be provided) with a free service.

      • RD20

        Except for that whole pesky thing about not being supposed to charge for wow related content you know what carbonite got in trouble with.

  • Vincent Vasquez

    I’ve been wondering, does using the older Elder Charms of Good Fortune affect the increasing chance in any way? Or are those and the Mogu Runes of Fate on their own tables?

    • zoopercat

      Ah, good question. So they are on their own tables, but it’s more than that actually. Each bonus roll only affects that boss. So if you use a bonus roll on Horridon on week 1, you’ll get an increased chance on Horridon next week if you use another roll. If you use a roll on Horridon on week 1, and use it on the Council on week 2, you have no increased chance on the Council.

      Does that make sense?

      • Vincent Vasquez

        Alright, so in that case, say I spend all my runes on one boss in one day by requeueing over and over. The chance would increase every time I spent a rune until I won something right?

        I’m trying to pick up the ToT strength polearm. : /

        • Vincent

          For what it’s worth, (even though this is an old thread), the answer to your question, Vincent (nice name) is yes. Hope you were able to either get that pole arm or find something new and shiny in SoO. :)

    Why isn’t there a paypal option to pay 1 usd a month?

    • zoopercat

      Because of paypal’s fees, we don’t offer monthly plans through them, we’d have to charge too much for it to even make sense.

      You can pay monthly using the credit card form on our site, which goes to Stripe (a payment company with several ex-paypal people involved). If you signup for the monthly plan there, it’s $2 a month. The reason it isn’t $1 a month is because we are charged per transaction, so 12 transactions instead of 1 in a calendar year adds up to a lot. So the annual people get a discount – we pass the savings on to them.

    How bonus roll works : U got a ring defeating the boss, then u use a coin to get a bonus, then u gert another of the same ring… amazing….its blizzard inteligence

    Next quarter they’ll be luck if only drop to 6 million subs….

  • Ken

    Wow Patrick, you are a real prick. Its not good enough for you that you get a cool tool you can use for free, you want everything for free. I bet you don’t work for free.

    • Sarg

      I bet he doesn’t work.

    If you can’t see the value this sight adds for a $1 a month you can’t have a job. This is a awesome sight to use with ur guild that allows you to give valid advice in seconds that in times past would have taken real valued game time away to help someone often with a much greater margin of error for pennies. I for one thank you for your efforts and the very low price for great service. If you don’t like it don’t use it. If you don’t pay you really lose a lot in my view to bitch about it.
