only if you were a defense pure and were super rich
The name is mithril dragon. 2540 life points. Their combat level is 304.
Mithril Dragon's are level 304, and are not to be taken lightly.
No, level 128 ghosts that are in the RuneScape wilderness will not drop Dragon Full Helms. The only RuneScape monster that drops the Dragon Full Helm is the Mithril Dragon which has a combat level of 178 and drops the helm as a "very rare" drop.
If it is a Draconic Visage that you seek: In order of Name - Level - Attacks is uses - Your Suggested Items - Mithril Dragon ( Level 304 - Melee, Ranged, Magic ) - Ranged + anti ( Crossbow - Ruby(e) ) - King Black Dragon ( Level 276 - Melee, Ranged, Magic ) - Same as Mithril Dragon - Steel Dragon ( Level 246 - Melee, Magic - Breath - Mage Prayer not 100% Effective - Same as Mithril Dragon - Black Dragon ( Level 227 - Melee, Ranged ) - Same as Mithril Dragon, can also be meleed. - Iron Dragon (suggested) ( Level 189 - Melee, Magic ) - Same as Mithril Dragon - Skeletal Wyvern ( Level 140 - Melee, Magic ) Quite strong, you may need anything with high mage defence, black d hide or Kharils + an elemental shield ( must have ) + protect from melee you will also need 72 slayer to kill this monster.
Adamant Dragons do not exist. The highest-tier metal dragon is still Mithril.
Killing high-level dragons, King Black Dragon and Mithril Dragons work best.
When your combat level is equal or higher than the green dragon. Since there are different types and different levels, I wont post the level needed. Just get an equal or higher combat level.
I would have to say combat level 89 or 77
A bronze dragon's combat level is 124.
Combat level in general is not relevant; specifically, you need Defense level 60.
Corporeal Beast, Mithril Dragon, Kalphite Queen, King Black Dragon, Tormented Demons, Chaos Elemental.
To make mithril crossbows, you need fletching 54. I am not sure whether there are other types of mithril bows.
