Strength (STR) is a character stats that affects critical hits, damage done to a boss, and the effects of two skills used by Warriors and one of the Rogues' skills. It is therefore the primary stat for Warriors and the secondary stat for Rogues, though all classes get the passive bonuses described following.
This stat increases the chance that a player will land a critical hit when scoring a task and increases the bonus gained from critical hits. It also increases damage dealt to bosses. Both normal damage and damage from a critical hit are increased.
A player of any class can increase their own Strength by allocating stat points to it or by equipping armor and weapons that provide a bonus to the STR stat. Warriors and Rogues gain an additional class bonus for wearing the STR-providing weapons and helms that are specifically intended for their class.
Warriors can use the skill Valorous Presence to buff their own and their party mates' Strength by an amount determined by their own unbuffed Strength, and increased Strength will also increase the effect of Warriors' Brutal Smash skill and Rogues' Backstab skill.
Scoring[]

Strength improves the chance and magnitude of critical hits.
Specifically, Strength points have the following effect on critical hits and damage:
- Increase the chance of a critical hit by 1% of the base value per STR point (initial chance is 3%, so a STR of 100 would double the chance to 6%).
- Increase critical hit bonus (initially by around 2% per STR point, but gives diminishing returns - as STR is increased, each extra point of STR provides a smaller increase to critical hit bonus).
- Increase damage dealt to monsters during boss quests by 0.5% per STR point (a STR of 50 would multiply the damage by 1.25).
- This boss damage increase is calculated before any bonus from a critical hit (a STR of 50 would increase boss damage by a multiplier of 1.25, before the STR 50 critical hit multiplier of 2.3, for a total multiplier of 2.875).
