Corrupted Boar Tusk is a Shroud material that comes off the Fell Boars roaming inside the fog. These are the corrupted boars that glow with blue Shroud light, and they are concentrated in the Shroud of the Revelwood, with a smaller number in the Shroud of the Blackmire. In the game, the item reads as “A jagged tusk that’s been tainted by the Shroud. Pulsing with faint traces of toxic energy.”
Quick answer: Kill Fell Boars inside the Shroud. Each one drops 2 Corrupted Boar Tusks, so eight kills cover the 15 the Flame Altar upgrade needs.
