• If your current level is 15 or below, you need a static 17 experience to gain the next level.
• For current levels from 16 to 30, each level takes 3 more experience, amounting to (17 + (currentLevel - 15) * 3) experience to gain another level.
• At and above level 31, each new level takes 7 more experience, totaling (62 + (currentLevel - 30) * 7).

The total XP required for a given level (x) can be calculated as follows:

• for x≤15: 17x
• for 16≤x≤31: 1.5x² - 29.5x + 360
• for x≥30: 3.5x² - 151.5x + 2220
