Infernal cape

An infernal cape is a superior variant of the fire cape awarded for completing the Inferno. It has over twice as many offensive bonuses as the fire cape, along with unrivaled defensive bonuses. In terms of overall bonuses, it is the most powerful melee cape in Old School Runescape.

However, the Ardougne cloaks 3 & 4 still surpass it in stab attack and prayer bonuses, while the mythical cape surpasses it in crush attack.

An infernal cape can be exchanged for a chance of obtaining the Jal-nib-rek pet by speaking to TzHaar-Ket-Keh. Like killing TzKal-Zuk, there is a 1/100 chance of obtaining the pet this way. If the player already has the pet, capes cannot be exchanged.

The infernal cape can be combined with the max cape to change its appearance by turning it into the infernal max cape.
