Ahrim the Blighted

Ahrim the Blighted is the oldest of the Barrows brothers. He uses low level curse spells as well as his set effect "Blighted aura", which lowers the player's strength and attack. This spell cannot be blocked in any way, ever. He uses Fire Wave, so it is advised to use the Protect from Magic prayer or wear armour with high Magic defence like black dragonhide armour. He can hit a max of 200 using Fire Wave.

Players may attempt to kill Ahrim without Prayer, but it is only recommended if you have 70+ Ranged and 80+ Magic as well as black dragonhide armour. Also, like every one of the Barrows brothers, his armour is tinted red. Generally, Ahrim is considered the weakest because he wears robes, as opposed to his younger brothers, therefore making it easier for players to land blows on him. He is weak against ranged attacks.

Trivia

 * The name "Ahrim" is likely derived from Ahriman, an evil spirit from the Zoroastrianism religion.
 * Even if you use the Protect from Magic prayer, his curse spells can still work, plus his set effect still activates because the attack still count as a successful hit, so bringing a regular stat restore potion is recommended.
 * Ahrim's fire wave used to have the old graphics despite the new update (this has been fixed as he now uses the new fire wave animation).
 * The in-game set of Ahrim's armour appears to be made of chain-link, while the other 5 barrows brothers appear to wear plated armour.
