(The author will add more as everything is introduced in the work; if you forget, feel free to come back and take a look.)
1) Elemental affinities are categorized into eight main elements so far:
- Fire
- Water
- Earth
- Wind
- Lightning
- Space
- Light
- Darkness (or Shadow)
(Each has sub-elements.)
2) Potential:
An individual's capacity for growth (the same applies to all the elements they have awakened) is assessed using a 25-star rating system divided into five tiers:
- Novice (1-5 stars)
- Adept (6-10 stars)
- Epic (11-15 stars)
- Legendary (16-20 stars)
- Mythic (21-25 stars)
Each tier is further divided into three stages: initial, middle, and final.
3) Elemental energy 'Evol'
It has eight distinct colors:
- Red Evol - Fire
- Blue Evol - Water
- Brown Evol - Earth
- Light Green Evol - Wind
- White Evol - Lightning
- Gray Evol - Space
- Golden Evol - Light
- Dark Evol - Darkness
Note: No one can forcibly absorb Evol for which they lack affinity.
4) Crystals that serve as gateways to other dimensions and realms (in the air) are also divided into five tiers:
- Novice
- Adept
- Epic
- Legendary
- Mythic
(The larger the crystal, the stronger the monsters.) They have 4 colors:
- White Crystal (safe)
- Gray Crystal (a high but manageable number of monsters)
- Orange Crystal (the realm inside requires urgent clearing to prevent a breach)
- Red Crystal (will shatter, releasing all the monsters inside into the surroundings)
