Primalwill Conflagrantweave reduces the balance recovery after using the ability.  The ability's already extremely useful for slowing down the opponent's momentum, and reducing the balance only makes it better for racing an opponent's momentum.

Primalwill Slough makes the ability balanceless, though it still requires balance and equilibrium to use. Balanceless slough can be used immediately before another ability, allowing you to avoid locks or slow enemy affliction momentum without hindering your own momentum.

Primalwill Smoulder does additional damage. Primarily you use this with Explosion to get the additional damage from ablaze on the target.  With full Spark and Brand, and sensitivity stuck, Explosion plus Primalwill Smoulder can kill at 60% health or more.

Primalwill Blister knocks balance and prevents non-standard healing abilities. Can be useful if an opponent is relying on them.
