Gems & metals appear on every beast, even those you fight against in the game.
They effect your beast's strengths and weaknesses as shown in the chart below.
After some extensive testing, it appears that every beast has a "random" factor to their stat numbers.
There is no formula that works the same exact way every time.
Using the best gems and metals only gives you a better "chance" of increasing your stats as shown above, but it's still rarely ever the exact same even with 2 same beasts with same gem/metal.
See Beast Stats page for info on which stats do what exactly.
Tips for boosting your beast's stats:
- Gems and metals appear randomly on each beast and they effect its stats as shown below. Better gems/metals make your beast stronger. You can change the gem or metal of any beast with crystal shards (see Crystals & Capturing page).
- You can also boost a specific stat permanently, no matter what gem/metal you have with crystals (aka "Roids") which you get from selling/crystalizing unwanted beasts (see Crystals & Capturing page), but there is a limit to how much you can boost each stat which is somewhere around 125 points per stat (at lvl 60).
- Another way to increase all stats is Beast Fusion which you can do if you have 2 or more of the same beast (see Beast Fusion page).
- One important thing to note is, when capturing a beast (not hatching), no matter what metal you see on it, it will "act" as Iron (the lowest metal in the game) until you upgrade it with a shard higher than its current metal. So basically, ignore the metal you see on a CAPTURED beast and assume it is Iron. I guess this exists to give a little extra incentive for us to hatch beasts and raise/train them. In general, a fully raised beast will have higher stats than a captured beast.
