The Crit stats affect your Critical Rate, which is how often you are able to land critical attacks. The rate represents the percent probability that your attacks are being considered critical. Interestingly, your Crit score is not a factor on how much damage a critical attack deals (default is +100 percent).
Domination
Your Domination stat is the amount of additional damage you deal to players who've been injured or otherwise impaired. This is the case for enemies Staggered (stunned), Pushed (moved) or rebuked.
Swiftness
Your Swiftness stat determines how quick you are during combat. The stat can increase your movement speed and attack speed, and also reduces your class skill cooldowns.
Endurance
In addition, the Endurance stat is essential to your defense and health that is why it is a critical factor in combat for tank characters to prioritize. Endurance increases your physical and magical defense in addition to the efficacy of healing and shields.
Expertise
The Expertise stat dramatically alters the way Debuffs affect both you and your foes. Expertise can increase the duration of Debuffs when they are cast upon opponents and increases the severity caused by Stagger effects. Additionally, it decreases the duration of Debuffs that are cast on you.
Specialization
The Specialization stat is unique to your specific class. The ability, the class skill forms, or distinct varieties of damage will be enhanced when you place points into Specialization. For instance, Specialization points for the Paladin sub-class improve the effectiveness that you can use Holy Aura, the rate you increase your Piety meter, and also the impact of Awakening. Go to the Specialization section of your Character Profile to see how it affects your specific class.
From challenges to free roaming, you'll always find something that will test your skills through Lost Ark. At some point, you'll need to confront world bosses, which are massive creatures that can be found within certain regions of the map.
World bosses are generally more powerful than normal monsters, and they're unlikely to always be around. If a world boss dies it will take about 30 minutes before it respawns. If you're unable locate a world boss within its dedicated spawn, you may need to come back sometime later or be the first person to take it down again after it respawns.
