Strength

is one of the core player Stats. It plays a major role in determining the damage dealt by the player.

Mechanics
is one of the statistics in the damage calculation when using a melee or ranged weapon.

The formula is as follows:

$${\left\lfloor{\left(WeaponDMG + 5\right) \times \left(1 + \frac{STR}{100}\right) \times \left(1 + \frac{CritDMG}{100}\right) \times \left(1 + \frac{\text{Additive Multiplier}}{100}\right)} \right \rfloor = \text{Damage}}$$
 * WeaponDMG: weapon's damage stat
 * STR: strength (including base strength)
 * CritDMG: critical damage stat (including base critical damage)
 * Additive multiplier: combination of boosts from abilities and enchantments

At the start of the game, players have a base of 0. It can be increased by:
