# Training Players, Battle Points & Summon Cost

All players have a Player Level.  This player level is what adds to their total Battle Points.\
\
A Player can be TRAINED in 2 ways:\
1\)  by spending their own CANDY (off chain currency made from playing off chain games, gifting and more...) OR\
2\) by friends/others if those others look that that Players profile and tap the train button.

\
A player **Battle Points** are comprised of:\
1\. the player level\
2\. the player's current equipped Mystic NFT's Power Level

With these combined values the player's card (when used in Battles) has a Summon cost derived from the Player Level + Current Mystic Power level 

Here is the current SUMMON COST formula (subject to balancing):\
X = (currentMysticPowerLevel + (mysticTypeCount > 1 ? 1: 0)) 

finalSummonCost = (X > 10 10 : X ) - (player level/10)
