Cursed technique: "Lvl up"
Lvl up:
The user can level up by defeating curses and distributing points among: strength, speed, and cursed energy.
The effects of the technique last for 2 hours from when it is activated. After that time the user's levels are reset and their attributes return to their base values.
The user gains experience points depending on the grade of the curse:
Grade 4: 1 experience point
Grade 3: 3 experience points
Grade 2: 10 experience points
Grade 1: 25 experience points
Special Grade: 80 experience points
To level up from 1 to 2, need to gain 10 experience points. From 2 to 3, 15. From 3 to 4, 25. And so on, with an exponential experience curve, meaning that each new level requires more experience to reach the next.
Each level achieved grants 8 skill points, which the user decides to spend on one of the 3 attributes: strength, speed, or cursed energy.
The user can see a kind of interface, like a character sheet of himself where he can see his progression, the experience he needs to level up, his attributes etc.
Domain expansion: "Dungeons and Curses"
The user can only expand his domain after reaching at least level 3 (a binding vote based on RPG games where a certain level must be reached before entering dungeons)
Visually, the domain resembles a stone dungeon, surrounded by columns with torches and featuring a huge chest in the center of the room. All of this is recreated in a pixel art style.
The guaranteed hit of the domain is not lethal, and it's instantaneous. It causes the target to see a sort tutorial explaining how Saito's cursed technique and domain works.
As for Saito, within his domain he can open the chest in the center of the dungeon. This chest can contain various items, such as cursed tools that increase his attributes or even level-up potions. The higher his level when expanding his domain, the greater the chance that the item he receives will be of a higher rarity (common, good, epic, legendary).
