At level 91 Agility, you’ll unlock the last shortcut. Most players don’t see a reason to train the skill beyond this level because they gain access to all the rewards the skill has to offer. However, this isn’t the case. Once you reach level 99 Agility, you can purchase the skillcape from Cap’n Izzy No-Beard. He is a pirate captain located at the entrance of the Brimhaven Agility Arena minigame. The skillcape provides +9 Defense stats and +4 Prayer if trimmed. Also, it can substitute for the graceful cape, giving you -4kg weight reduction and 3% run energy replenishment. Finally, it can be used to restore your run energy to 100% once per day.
