PRIMARY STAT
The primary stats are the six basic stats a hero has,
and the secondary stats are calculated based on these.
When creating a hero NFT,
the SP between min : 15 ~ max : 21 is randomly distributed to 6 stats.
Among these values, it is a rule that the value of 2 is distributed equally among the 6 stats first, and the remaining values are distributed randomly.
The higher the stat value, the less likely it will appear.

When you level up by collecting exp through hunting,
you get 1 SP for each level up.
SP can be distributed among the 6 primary stats in each hero’s detailed information.

You can reset stats by purchasing the Book of Oblivion with XTO coins.
The primary stat value may be added depending on the options the weapon or orb has.
However, even if you proceed with stat initialization, the initial stats distributed when the initial NFT is issued do not change.
HERO’S SKILLS
Each hero has a total of 7 skills,
When a hero is summoned,
two skills are randomly selected from among them.
When you upgrade a skill,
the attack power of the skill or the buff value of the skill increases.

The basic stats and skills of the hero confirmed through summoning cannot be changed.
Find a hero that fits your strategy through market trading between users.
