Android When you match 3 yellow gems, you receie only 2 mana instead 3. 5 mana instead 6 when mana surge. Blue gems gives you normal 3 and 6 mana as usual. It happens all the time. ---

Yes, to expand on what Dorgath is saying: Some banners actually subtract from a color. If you’re consistently getting -1 to your gem matches, it’s likely you’re using a banner that does that. For reference, the banners that subtract from yellow are: - Abyssal (Blighted Lands) - Slayer (Divinion Fields) - Trident (Merlantis) - Sorrowful (Sea of Sorrow) I wrote a tool at [http://slypenslyde-labs.glitch.me/gemsofwar/bannertool.html](http://slypenslyde-labs.glitch.me/gemsofwar/bannertool.html) that isn’t quite finished but can help. There’s another guy who has a handy reference chart I haven’t stashed the shortcut for yet. ---

Hi @Pin Can you please [use the bug reporting template](https://community.gemsofwar.com/t/gems-of-war-how-to-report-a-bug-or-game-glitch/37013) when making a report. Otherwise I’m going to ask you a number of questions which are written there and I look crazy. 😉 Some of them seem redundant but it’s necessary to help the team reproduce the problem and then resolve it.
