Infernal cape

An infernal cape is a superior variant of the fire cape awarded for completing the Inferno. Due to having just over twice as much offensive bonuses as the fire cape, along with unrivaled defensive bonuses, it is the most powerful melee cape in Old School Runescape. However, Ardougne cloaks 3 & 4 still surpass it in stab attack, magic attack, and prayer bonuses.

An infernal cape can be exchanged for a chance of obtaining the Jal-nib-rek pet by speaking to TzHaar-Ket-Keh.

Trivia

 * The first player to obtain the cape was Woox, who claimed the cape two days after release.
 * As the first player to complete the Inferno, he was awarded a real-life version of the Infernal cape, a RuneFest 2017 ticket with full-expenses paid travel, and lifetime membership.
 * The infernal cape, infernal max cape, fire cape, and the fire max cape are the only capes to have an animated texture whilst wearing them.
