Flask of Fervour is a tier 8 relic in the Demonic Pacts League which grants the flask of fervour.

• When the Flask is consumed:
  • Your Hitpoints will be restored to full.
  • Your prayer points will be restored to full.
  • Your special attack energy will be restored to full.
• Over the next 2.4 seconds the sigil will:
  • Trigger three explosions which deal 60% of your base Prayer level (30% in PvP) to all enemies within 3 tiles of you as typeless damage.
  • Reduce all damage you take to 0.
  • Not deal damage to Yama.
• This item has a base cooldown of 3 minutes
  • For every 10 damage you deal in a single hit, reduce the cooldown by 0.6s. This counts each individual hitsplat for multi-hitting weapons and AoE attacks and is calculated by factors of 10: dealing 0-9 damage provides no reduction, 10-19 reduces cooldown by 1 tick, 20-29 reduces by 2 ticks, etc.

• The flask can be used shortly after you have already reached 0 hp and will successfully "parry" death.
• The flask will spawn in your inventory with its cooldown reset when you enter The Gauntlet
• The flask of fervour can be retrieved from the Leagues Tutor in Yama's Lair if lost.
• The explosion will damage NPCs if any of their tiles are within the 7x7 blast range.
• Its own explosion damage does not reduce the cooldown.
• The explosion will not damage the Moons of Peril, Nightmare, Phosani's Nightmare or the Great Olm.
• The damage from the explosion benefits from the Demonic Pact effect that causes recoil and Thorns style effects to deal additional damage equal to 1% of your total defence bonuses.
