Experience Points
Adventurers need experience points (XP) to level up and become stronger. We want to show the total XP a player has gained given their current level.
Each character starts with 0 XP at level 1. To reach the next level, they need to accumulate additional XP equal to their current level times 5.
For example:
At level 1, XP is 0.
To reach level 2, we need 5 XP (
1 * 5) added to the current XP so far (0).At level 2, XP is 5.
To reach level 3, we need 10 XP (
2 * 5) added to the current XP so far (5).At level 3, XP is 15.
To reach level 4, we need 15 XP (
3 * 5) added to the current XP so far (15).And so on...
To summarize the calculation in a table:
| Level | XP so far | XP for next level |
|---|---|---|
| 1 | 0 | 5 |
| 2 | 5 | 10 |
| 3 | 15 | 15 |
| 4 | 30 | 20 |
