Dragonfire shield

A Dragonfire shield, when fully charged, is the strongest shield in game, only second to Crystal shield in range defence. To wield this item, a player's Defence level must be 75. It can be smithed at a Smithing level of 90, combining a Draconic visage with an Anti-dragon shield, earning 2000 Smithing experience after a few clicks. If you don't have the required Smithing level, you can also bring the required items and some money to Oziach who will smith it for you (for the hefty price of 1 250 000 coins, which is the most any NPC charges for any transaction).

This shield provides protection against dragonbreath (and also the breath of skeletal wyverns) like the Anti-dragon shield, but the dragonbreath is absorbed and stays in the shield, giving it charges. The maximum number of charges the shield can hold is fifty, and every charge increases its defence against stab, slash, crush and range attacks by +1. Also, its strength bonus beats both the Rune defender and Toktz-Ket-Xil by 2.

When the shield is worn, players can also release charges of dragonbreath by operating it. To discharge the flame, right-click on the equipped shield while in combat and select 'Operate'. The shield will then fire a deadly blast of fiery energy at the opponent, potentially inflicting massive damage (potentially beyond 40). Most players, however, state that the blast hits around 25 at most.

The shield will need to cool down for exactly two minutes before the player can unleash its flames again. The only other pieces of equipment to have this ability are Enchanted dragonstone bolts. After using a charge, the player must wait some time before operating it next time.

Note that only adult black, iron, steel and mithril dragons, the King Black Dragon and skeletal wyverns will drop draconic visages.
