Uses in PVP

Assassinate lands a guaranteed CRIT.

Put her in the first slot/make her move first in both PVP offence and defence so she can use her Blade Storm Icon.png Blade Storm as soon as possible. Not making her have her turn first gets her risked being stabbed in the back and killed by Shadowblade token 0.png Shadowblade, or shot by Willow token 0.png Willow Swift if she cannot dodge the arrow with help of Agile Icon.png Agile.

Notes and Tips

Her 2nd and 3rd special attacks, Assassinate Icon.png Assassinate and Assassin's Wrath Icon.png Assassin's Wrath, guarantee a CRIT even when Black Diamond is diseased (normally the Diseased debuff blocks the chance to land critical hits).
