Oberon’s third ability is Renewal. Oberon releases healing energy that heals nearby allies and regenerates health over time. This ability creates a permanent field in the area where it is cast. Allies close to Oberon when he casts Renewal will be healed and they will also get a health regeneration buff that remains while Renewal is active, regardless of range. Allies that enter the field after the ability is cast will also get the regeneration buff. Fully healed allies will also be healed of any negative status effect.
Anyone that stands on Hallowed Ground with the Renewal buff will get a bonus to armor while Renewal is active, even if they leave the Hallowed Ground. If Renewal is deactivated the armor buff will persist for short duration. While active, Renewal will also slowdown the bleedout timer of any incapacitated allies. Renewal will constantly drain Oberon’s energy for each ally affected and will last until it is deactivated or Oberon runs out of energy.
Ability Strength mods affect the base damage of Smite and its number of projectiles, the damage and status chance of Hallowed Ground, the initial heal and health over time of Renewal and its armor bonus, and the damage of Reckoning. Ability Range mods affect the cast range of Smite and its projectiles homing range, the radius and angle of Hallowed Ground, the field radius of Renewal and the radius of Reckoning and its blinding effect. Ability Duration mods affect the lifespan of Smite’s projectiles, the duration of Hallowed Ground, the energy drain per second of Renewal and the duration of its armor buff when it is deactivated. It also affects Renewal’s bleedout timer slowdown and the blind duration of Reckoning.
So, all things considered, here are some builds you may want to try on your Oberon:
