Leveling guide

So, you want to level your Riders? Here are some pointers

Choosing the food trainers
To maximize EXP gain, have those in mind: It's better to give all those Short-type Shocker Riders to a Short-type character. Save those for the Riders you want to keep. A 1* crystal will give 2600exp, and if it matches the type of the Rider you're training, you'll get 3120exp. You'll waste TP and they hardly give more EXP when you fuse them back onto someone else. For instance, 1* characters only give 200exp, 2* 600exp, 3* 2100exp and so on. This also applies to the crystals. They only give 200exp. You're going to end up wasting TP. The best way to level is by gathering specialized crystals and using them all at once.
 * Same types give +20% more EXP
 * EXP crystals give BIG amounts of EXP
 * Absolutely avoid leveling characters you think won't keep.
 * The higher the rarity of the character you're feeding to your Rider, the higher the EXP you'll gain out of them
 * Using a tons of 1* as material isn't a good idea.

There is also a chance that, while fusing, you may have "Great Success" in your training. What this means is that you get a an exp boost, but how big said boost is, is yet to be determined. Further testing is necessary.

TP cost is calculated by the simple formula: 100*[RIDER'S CURRENT LEVEL]*[# OF CHARACTERS BEING USED TO TRAIN]

Limit Break
A Limit Break increases the maximum level of your rider by 5.

In order to cause a Limit Break, you must use one or more characters with the same name. Eg.: Long-type Shocker Grunt can be used to Limit Break a Short-Type Shocker Grunt.

KEEP IN MIND that the rarity of the character also affects the Limit Break. This means, for example, a 1* character cannot Limit Break a 2* character, or vice-versa.

Being the same character does not mean it enables limit breaking. For example, while 1* Middle-type Rider 1 Sakurajima ver. can be used to Limit Break 1* Short-type Rider 1 Old ver., 2* Middle-type Gaim Ichigo Arms can't Limit Break 2* Support-type Gaim Orange Arms.

You are able to Limit Break an already evolved character. There doesn't seem to be any stat advantages to Limit Break a character before evolution (or at least what has been tested so far), so it's recommended to not Limit Break a character you wish to evolve later on; this will save you 5-20 levels of EXP and TP.

As always, further testing is required.
