Return to Bone
Obsidia gains Bone Energy whenever she deals damage. Basic Attacks grant 1 Energy against non-hero units and 2 against hero units or Turrets. Skills grant Energy equal to 3 times the amount granted by Basic Attacks against the same unit type. No Energy is gained from hitting creeps. When Bone Energy reaches 30, it forms a Bone Shard, up to 25 shards. When Obsidia uses Basic Attacks, all Bone Shards strike the target, each dealing (+6% Total Physical Attack) Physical Damage and inheriting 6% Attack Effects. Killing an enemy hero directly grants 1 Bone Shard(s). Obsidia's Basic Attacks deal 70 (+70% Total Physical Attack) Physical Damage, inheriting 100% Attack Effects.
