Mithril dragons are a nostalgiac, hardy dragon that most of us probably remember trying to kill as a kid. They were introduced along with cheap osrs gold the Ancient Cavern as an upgrade from Steel Dragons from years past and came with a shiny new Dragon Fullhelm as a drop.
Unfortunately, they’ve never really been easy or profitable to kill due to how inaccurate even maxed players will hit against them.
Since this dragon has an extremely high base defense with the only stab being a slight weak point, the idea is to get the best stab & strength set up to get in some his. This should either use the Dragon Hunter Lance or a Zamorakian Hasta, with the former having a 20% accuracy bonus against any dragon.
The armor should be made up of Bandos armor with a fighter hat (for accuracy) and Primordial Boots. A Dragonfire shield is a must-have for offensive stats, defensive stats and how it can ward off the dragon’s powerful breath. An extended anti-fire potion should still be used in combination.
An amulet of torture should be used in the necklace slot, although a fury would be suitable as well (having a stab bonus). Barrows Gloves, an imbued Treasonous Ring and any god blessing would be other suitable accessories.
While an Inferno Cape would be good, any tier of Ardougne cloak would be better due to the stab accuracy and prayer bonus. Any skill cape would also do OK for the prayer bonus, but it would be less than efficient.
Your backpack should consist of Super Combat Potions, a few prayer potions and lots of high-healing food to endure the fight. Saradomin Brews or combo food isn’t really necessary as this isn’t the type of fight for damage to stack up against you like other bosses.
