How to unlock the Poison weapon affinity in Elden Ring

Elden Ring players can modify their existing weapons and enhance them using different types of affinities. Depending on the type used, affinities can greatly affect how weapons work in terms of damage, status effects, and more.

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.

To unlock the Poison weapon affinity, players will need to gain access to the Black Whetblade. This whetblade can add Poison, Blood, and Occult affinities.

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.

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