Hitpoints experience can be earned by dealing damage to Monsters. 0.133 XP is awarded per point of damage done to a monster. This experience can be increased by 7% by equipping the Gold Emerald Ring.
Recovering Hitpoints
Hitpoints are passively regenerated once every 10 seconds, with 1% of your max health being gained per interval by default. This can be increased by an additional +10 if the File:Hitpoints Skillcape (item).pngHitpoints Skillcape is equipped, +6 when the Shaman Ring is equipped, and +50 when the Pillar of Combat Agility Pillar is active. In Adventure mode, these flat regeneration amounts scale to +100, +60, and +500 respectively.
Equipping the Gold Ruby Ring increases this amount (including any flat bonuses) by +10%, and using the Unicorn familiar increases by +50% (with many Unicorn synergies providing additional regeneration bonuses). The Rapid HealPrayer further increases the resulting amount by +100%. Regeneration Potions provide a 30-150% chance to double the amount. These multiplicative bonuses may stack.
The amount of Hitpoints regenerated can be calculated as follows:
[math]\displaystyle{ \text{HP Regenerated} = \left \lfloor \left ( \frac{\text{Player Maximum HP}}{100} + \text{Flat Regeneration Bonus} \right ) \times \left ( 1 + \frac{\text{% Regeneration Bonus}}{100} \right ) \right \rfloor }[/math]
