Old Wolf

The Old Wolf is a stronger Wolf with, found in specific areas of the Ruins, namely the Throne Room, in the chamber below the Throne Room, behind the Ruins to the west as well as on the balcony of the Lonely Philosopher's tower.

It drops more bones than a normal wolf. It was added in the Slayer update as a high-exp option for completing slayer quests.

It has a low chance to drop the Wolf Talisman.

Caution
Old Wolves are extremely dangerous enemies to face off against, and they should just be left alone, unless you can defeat them. With a fast movement speed, ridiculously high damage output, and a colossal amount of hitpoints (equal to around 7.5 Crypt Ghouls), Old Wolves are comparable to some weak Minibosses and have 2k more hp than Zealots. If one chooses to farm these for Wolf Talismans, then one should invest in high protection Armors, such as a Dragon Armor or others. Also, one should use a sword which can do at least 3k a hit, such as a fully enchanted Aspect of the End, a max Raider Axe, or a max enchanted Golem Sword. It is also recommended to use a pet that grants either damage, like the Enderman Pet, or true resistance, such as the Silverfish Pet or a Wolf Pet.
