    stats: {
        attack: 11,
        defense: 11,

Moves

Hit Points (HP)

When a pokemon uses a move that has power then the damage should be calculated and the resulting value should be decremented from the defending pokemons hp

If a pokemons hp attribute drops to zero or below it loses the battle.

Damage Calculation

• Power is the attacking pokemons moves power
• A is the attacking pokemons attack
• D is the defenmding pokemons defense
• Modifier for this example will always be 0.1

Damage should be an integer not a float.

Stat altering moves

Growl and Leer can reduce the opposing pokemons stats within the current battle.

Growl affects the defense stat.

Leer affects the attack stat.

Stats can only be decreased a maximum of 6 stages.

Stage	% Of Base Stat
0	100%
-1	67%
-2	50%
-3	40%
-4	33%
-5	29%
-6	25%
