A VAMPIR mount is a stat item first and a ride second. There are six grades, higher grades carry higher stats, and from hero grade up you can re-summon a pull up to five times with diamonds and keep one result. Duplicates of the same grade synthesize into new or higher mounts. The appearance toggle lets you ride the look of one mount on the stats of another.

Grades and re-summon

Normal, advanced, rare, hero, legend, mythic. Re-summon opens at hero: each of the up to five rerolls costs more diamonds than the last, and at the end you pick one mount from everything you saw. The probability page also states that an 11-pull does not change the odds: every pull inside it uses the single-pull rate.

The appearance setting is an ON/OFF toggle: you keep the equipped mount's stats and show another mount's look. The look mount contributes nothing to stats. If a legend mount is ugly but strong, this is the fix.
