Inferno dragon

The inferno dragon is a level 109 dragon that can be found in the Tzhaar-Ko Dungeons. There are only two of them, and they are the third most powerful monster in the dungeons. They require level 81 Slayer to kill; however, they are not assigned as tasks by Slayer Masters. They can, however, be killed in place of red dragons on a Red dragon task, but this is not recommended, as regular red dragons are far easier to kill. Other than for Slayer tasks, they are mainly fought for the valuable Vial of flames that they drop, which goes for around two million coins on the Grand Exchange.

They are more powerful than their combat level suggests, as their dragonfire attack hits higher than that of any other dragon (however, Inferno dragons will use their dragonfire attack less often than others). A dragonfire shield is suggested, as sometimes (albeit rarely), their dragonfire can destroy your anti-dragon shield; however, the dragonfire shield and the supreme dragonfire shield are completely immune to breakage. A blessed dragon kiteshield can be broken, but breaks a lot less often than a regular anti-dragon shield.

Strategy
The Inferno dragon is weak to water spells, which should be taken advantage of. Rangers can also reliably kill Inferno dragons with bane bolts and arrows. However, regardless of what combat style is used, a dragonfire shield is heavily recommended.
