In Avowed, Sapadal's offer of power, much like a previous "Voice" offer, initially presents a difficult choice. However, a comparison of the resulting abilities reveals a clear winner.
Should You Accept Sapadal's Power?
For optimal godlike strength in Avowed, accepting Sapadal's offer during the "Ancient Soil" mission is strongly recommended. The resulting ability far surpasses the alternative.
The Benefits of Accepting:
Accepting grants the "Thorn of Sapadal" ability: "Fires a thorn of energy that passes through multiple enemies, causing damage on impact and momentarily Rooting them in place." This ability offers significant advantages. It's a potent damage source and the root effect creates excellent opportunities for combos, such as providing extra time to cast spells like Fireball.
Rejecting Sapadal's Offer:
Refusing Sapadal's offer provides "Godlike's Will," granting an extra Ability Point for the Fighter, Ranger, or Wizard trees. This is identical to the reward for refusing the "Healing Touch" earlier. While an extra Ability Point is helpful for skill progression, it pales in comparison to the unique and powerful Thorn of Sapadal.
The only reason to reject Sapadal's offer is to intentionally increase the game's difficulty. For an optimal build and enjoyable experience, accepting is the superior choice.
Having accepted Sapadal's power, consider acquiring Hylea's Talon for weapon and armor upgrades. To adjust your build, learn how to respec in Avowed and reallocate Ability Points.
