XP Boost effect (
/effect add <player> xpalchemy:xp_boost_effect <duration> <amplifier>)<amplifier>: 0 = x2 XP, 1 = x3 XP, 2 = x4 XP, 3 = x5 XP, etc...
Experience Debt Effect (
/effect add <player> xpalchemy:xp_health_debt_effect <duration> <amplifier>)- This effect has no actual effect on duration, but it's a fancy way to see when you are using your Experience Debt.
Planned
- Allow the potion to spawn in dungeons
- Stuff Enchantments that multiplies XP obtained when wore (more likely armor enchantments, maybe items too?) [Non-cumulative]
