Sunspear

The Sunspear is a main-hand melee weapon that requires level 75 Attack to wield. It is earned upon completion of The Lord of Vampyrium. Like blisterwood weapons, it can damage all vampyric creatures, though the damage does not increase with the number of vyre corpses cremated.

During River of Blood, the sunspear is reforged into its former glory by combining it with a blisterwood shaft and a wolfbane making a sunspear (melee). This upgraded weapon can be toggled into a sunspear (magic) or sunspear (ranged).

Vyrewatch, vyrelords, and vyreladies killed with this weapon will automatically have their corpses cremated, granting Prayer and Firemaking experience dependant on the player's levels. In addition, vyres killed this way have a 20% chance of dropping loot similar to that given by shiny columbarium keys. Cremating corpses in this way does not count towards the player's total.

If lost, it can be reclaimed from Ivan Strom for 100,000 coins.

When using abilities, the Sunspear can be combined with a higher-tier off-hand weapon (such as an off-hand drygore mace) to increase ability damage without impacting the ability to damage vampyres. Auto-attacks will require an off-hand blisterwood sickle in order to deal damage.

Should the player speak with Kara-Meir on Tuska's corpse while carrying the Sunspear she claims to still have it, and that it is a dagger, not a sword. She and the player then speculate that both weapons might have originated as parts of the same spear, hence 'spear' in the name of these weapons.

Note: charms are a second reward, obtained with other items

Trivia

 * An update was made to the Sunspear on 5 October 2015 that changed the cremation mechanic of the weapon. The chance of receiving loot similar to that of shiny columbarium keys has been lowered to around 20%, from 100%, cremation count will no longer increase while killing Vyrewatch with this weapon, and on the opposite side, will now grant up to 4x more Prayer and Firemaking experience per kill, based on your current levels.
 * A blisterwood sickle can have higher damage with sufficient vyre cremations, but the Sunspear will have better overall damage per second than even the maxed blisterwood sickle, due to its higher tier (75 instead of 70).
