Order of brothers: Dharok: you have to use protect from melee.

Equiptment: Just from taking a look at your current equiptment, I can tell you may be short on money. Some general changes you could make are upgrading the Rune/Dragon armour into Barrows armour, specifically Guthans (for set effect) or even Torags (such as exceptional defence bonuses). It's important to get boots/gloves/cape because every bonus counts. I would purchase Dragon Boots, or Rune, Rock Climbing, or even Adamant. To get a cape I'd strongly suggest an Obsidian Cape, but a God Cape (out of Mage Training Arena), or any other cape will suffice. Personally, I would change the Dragon Medium Helm to some Helm of Neitiznot, Berserker Helm, or a Dragon Total Helm for OSRS gold extra, more valuable bonuses. Also (this may be the most important thing)... Buy an Abbysal Whip... Very costly, but very helpful. If not bring a Dragon Scim, and DDS for spec.

I do not have a lot of expertise at Barrows, which means you will likely want somebody else to enlighten you on the next: Purchase: The generally accepted order of murdering the Barrows brothers is: Dharok, Karil, Ahrim, Verac, Torag, Guthan. You Will Have to pray against Dharok, Karil, and likely Ahrim. You may also choose to pray against the other three. Good Luck. 🩷Prayer is essential but 🩷is helpful for Piety. There are 🩷chief ways of barrowing - Slayer Dart, and Black Salamander. Black sallies require 🩷in ranged, magic, and attack. Their ammunition is Harralander Tar and it is very effective, but may be quite costly depending on your magic level. Slayer dart requires 🩷slayer, and it's principally used because if you loot the chest, you have a high chance of getting the runes for slayer dart ( 🩷departure rune/ 🩷brain runes per throw.)

Order of brothers: Dharok: you have to use protect from melee. Use your magical attack. Karil: if you've got leftover prayer, then use shield from missiles (Piety also helps a lot in this situation ). Switch to your melee weapon to kill him. Ahrim: if you have leftover prayer, then use protect from Old School RS Gold magic. Equip D'Hide, along with a crossbow or the shameful sally ranged style. Verac: if you've got leftover prayer, utilize it on keep from melee. Drink a Super Defence potion before looking for the sarcophagus. Take advantage of your mage style in great melee defence equipment (Rune+). Guthan: utilize your mage design in melee armour. Torag: utilize your mage design in melee armour.
