Players can imbue their weapons with affinities by using whetblades located throughout the Lands Between. When acquired, these whetblades allow players to add affinities based on the properties of whichever Ashes of War they use for their weapon.

Obtaining the Black Whetblade

To obtain the Black Whetblade, players must head to Nokron, Eternal City. The easiest way for players to locate this whetblade is to visit the Ancestral Woods Site of Grace.

Once players get there, they will want to jump down the ruins to reach an area called Night's Sacred Ground. Players will find the whetblade here.

Once players arrive at Night's Sacred Ground, they should begin looking for a corpse located in front of the altar there.

When players go up to the corpse, they will be able to interact with it and gain the Black Whetblade. Players can now use this Whetblade to add Poison affinity to any Ashes of War with the physical or occult types.

The uses of Poison affinity

Players can use the Poison affinity to boost dexterity, strength, and arcane scaling.

This affinity also adds poison build-up to the player's attack. This causes the target to build up a poison meter when struck. Once it reaches full damage, it will begin to cause poison damage to the target until the meter fades completely.

Elden Ring players can customize the vast amount of weapons at their disposal with different affinities. This can help enhance or even change some players' playstyles, so they align with their build or strategy.

All the affinities that players gain have different effects, so it is important to play around and discover the ones that appeal to them and are most useful.
