Strategies

• Sentinel Protector Defenders are considered the more offensive-oriented Defender branch that can block multiple enemies without having to use skills unlike Duelist Defenders.

Trivia

• When class branches was originally announced, Blitz and Liskarm were originally intended to be classified as Sentinel Protector Defenders, but are instead classified as Protector Defenders when Dossoles Holiday is released for unknown reasons.
