Itâ€™s pretty much like this.

Pretend you have zero masteries.

When you match 3 brown gems, you will get 3 brown mana. With zero masteries, you have 0% chance to surge.

Now, pretend you have 10 masteries, and match 3 brown gems. You will still get 3 brown mana.

But for every ten times (or so), one time you will get a mana surge. This means you double your mana, getting 6 brown mana.

Now pretend you have 100 masteries.

This does not mean you get 100% mana surge, that would be way too strong.

So the design team made the code so that the higher you go in mastery, the less you get in % chance to surge.

Letâ€™s pretend that at 100 masteries, you get 60% chance for a mana surge.

Thatâ€™s still pretty good. Every ten times you match 3 brown gems, six times you will get double mana.

Now, letâ€™s pretend that you have 100 masteries, you get 60% chance to mana surge, but the opponent has Jinx.

It does NOT cut your 60% in half. It cuts your â€ś100â€ť in half, back to 50.

It works as if you have 50 in masteries. But at 50, you still get a pretty good chance to mana surge, probably about 45% chance.

So even though jinx cuts your masteries in half, it only cuts your chance to mana surge down by 15%.

(In this pretend example.)

In my last example, letâ€™s pretend that you have a jinx on your team and the opponent has jinx on his team.

On your team, you have 100 masteries. But on his team, he has 200 masteries.

Originally, 200 masteries would give a really good chance, maybe around 70%! (Remember, this is not exact numbers, itâ€™s just giving you a rough idea how this works)

But when it cuts back to 100 masteries, he still gets 60%.

However, when your 100 masteries gets cut back to 50, you lose more than he does.

The bigger your mastery value, the less impact of jinx.

Thereâ€™s 2 more things you have to keep in mind.

- You can never get mana surge on 4 of a kind. So if you get a lot of these, you will
*not* get a lot of mana surges, compared to someone who always chooses 3 of a kind.
- You
*always* get mana surge on five of a kind. So if the opponent gets lots of these, he will get lots of mana surges for free, no matter if you have jinx or not.

I know that was a lot of words, but I hope it helped.
