Beast Claw is rewarded from Gurranq after giving him the fifth Deathroot. (If Gurranq is hostile after consuming the fourth Deathroot, he may be calmed down by reducing his HP.)
Effects
Put a hand into the ground and swipe forwards to unleash a cone of shearing claws that have SlashAttack Power equal to 193% of Incantation Scaling.
Charging the spell increases the Attack Power to 222% of Incantation Scaling.
Attack Power is boosted by 15% by the Godfrey Icon.
Since charging the spell already increases Attack Power by 15%, this increases the Attack Power by a total of 32%.
Strategies
Slash is a very give-and-take damage type, as naked and cloth-wearing enemies (such as Omens and Margit, the Fell Omen) are weak or less resistant to the damage type, while armored and scaled or rock-like enemies (such as Banished Knights, Dragons, and Sentry Stones) are far more resistant to it than other Physical damage types.
Can be jumped over.
The waves stick to surfaces, letting it travel up walls and hit enemies atop them.
