Upgrading mods...

On a gold mod secondary stats will increase 4 times. Those 4 could be any of that stat, so speed could be chosen 3 or even 4 times. As you found out, it can also not be chosen at all.

Welcome to mods.

It's more normal than getting speed to upgrade at all. What upgrades is chosen at random, with a random amount upgraded, with speed presumably having a lower chance than the rest. Of the 10 or so mods with speed secondaries that I purchased from the shop, 0 upgraded speed.

That stinks man. It's happened to me way too often.

Well that is annoying.

Thanks for the info, won't get so excited I see one of those in the store next time

It's normal. You're never guaranteed to get 4 different upgrades on a gold mod. You only get the assurance of seeing the non-upgraded speed already revealed, and the possibility that any (or all) of the upgrades could hit the speed stat. But it has been random, and still remains random, which stats will actually get upgraded.

If you're prone to donning a tinfoil hat, the rule of thumb is that the chance for the speed to upgrade is approximately zero percent by design, because that's how they get ya. :)

You are one of us now.....remember, greatness doesn't come overnight.

If I'm not mistaken, if you are willing to settle for one upgrade on speed, a level 1 green mod with speed revealed will upgrade the speed one time before revealing the 3 other stats.

But the compromise there is that the speed will upgrade precisely once, since there are only 4 stat upgrade chances in total for any mod, and the remaining 3 chances must be spent on revealing the hidden stats.

This is how it works:

every mod gets 4 secondary stats upgraded in total and each at levels 3,6,9 & 12 but note - it can be the same stat that gets the upgrade and there must be 4 different secondary stats by the time it reaches level 12.

Different coloured mods start at level one with a different amount of secondaries already there:
grey = 0
green = 1
Blue = 2
Purple = 3
Gold = 4

So for example a green level 1 mod will already have 1 secondary stat. you know it will upgrade at 3, 6, 9, & 12. you know it will have 4 secondary stats by the time it gets to 12. Therefore you definitively know that the first stat to get an upgrade will be the one already displayed. Then it must get the remaining 3 stats at 6, 9 & 12.

Similarly if you have a blue mod at level 1 it will have 2 secondary stats. This time you know it can upgrade those stats twice before it displays new stats i.e. at level 3 & 6. Then it will gain it's 3rd and 4th stat respectively at levels 9 & 12. Which of the two stats will get upgraded is random. it could be 1 each or it could be 2 and 0.

The reason this is important is that you can calculate what mod is worth upgrading and taking the risk on. if you upgraded every mod at random, you'd never have any credits.

Usually people look for speed. If you get a gold mod with +5 speed as one of the secondary stats at level 1 you could be in business. It could end up not upgrading the speed secondary stat in any of the 4 increases and will relatively be a dud. or you could get uber lucky and get all 4 upgrades on speed, taking it to 20+ speed secondary. I've only ever seen 1 of those in my arena shard.

I hope this helps. A good understanding of how mods work is probably the most crucial component to being successful in this game.

Do yourself a favor and upgrade to level 12 next time, before committing to the full level 15 mod. All of the final values for the secondaries will be revealed at L12, and those last three levels cost twice as much as the first twelve. If you like what you see at L12, then you can finish it up.

Yes that's a good idea :)
