Divine bastion potion

The divine bastion potion is a stat-boosting potion that combines the properties of a ranging and super defence potion for 5 minutes:

• Ranged will be boosted by 4 + 10% of the player's level (rounded down)
• Defence will be boosted by 5 + 15% of the player's level (rounded down).
• During these 5 minutes, the player's Ranged and Defence levels will not drain below the maximum boost of the potion.

Although natural stat drain is disabled, a player's stats can still be decreased or increased by the use of other spells and potions.

Once the 5 minutes are over, any stats normally boosted by the potion will be reduced back to their base level; Preserve does not affect the duration of the potion. Drinking this potion will also damage the player by 10 Hitpoints. Trying to drink the potion with less than 11 Hitpoints will instead prompt the message: You need more than 10 hitpoints to survive the power of a divine potion.

Players are unable to cast Boost Potion Share to share the effect across a group of players.

It is created by using crystal dust on a bastion potion, requiring 86 Herblore.

Mixing divine bastion potions yields 0.5 Herblore experience per dose.

Ranged boost is calculated with: ⌊RangedLevel×110⌋+4

Defence boost is calculated with: ⌊DefenceLevel×15100⌋+5
