Aura refresh (tier 4)

Aura refresh (tier 4) is a reward that can be bought from the Soul Reaper rewards shop for either 50 reaper points or 500 slayer reward points. It refreshes the cooldowns for tier 4 combat auras, specifically:
 * Aegis aura
 * Supreme invigorate aura
 * Supreme poison purge aura
 * Supreme reverence aura
 * Supreme runic accuracy aura
 * Supreme sharpshooter aura

Using the aura refresh on one of these auras will make it so you can immediately use the aura again.
