Melee spirit 1
Target: one creature

Level 21: "2d8 + Wisdom modifier damage."[PH2:121]
Protecting strike is an at-will power granted to shamans who select the Protector Spirit option for the Companion Spirit class feature at 1st level.
Shamans selecting the protector spirit generally need to keep the spirit companion close to the allies. Char-op considers the protector spirit weak choice because of weak output, but is the best healing option among the possible spirits. [1]
For shamans not selecting protector spirit, it is rated as a poor power, as the second at-will option should enable allies rather than be a light healing ability. [2]
