Boolean

That's quite a bit of effort though.. :L Might just leave it as it is.

That makes ALOT of sense.. So I guess there's no way to fix that apart from having the minimum requirement at level 7/8?

I currently have : public int experienceForLevel(int level) { int total = 0; for (int i = 1; i < level; i++) { total += i + 300 * Math.pow(2, i / 7.0); } return (int) (total * 2.5) / 10; } However it returns the wrong answer at low levels (1-12). For example, I have 276 experience in the Summoning skill, but it results in the level of 276, not 4. It works fine for higher levels. This is for a RS Tool im making.
