From Guild Wars 2 Wiki
Flanking refers to positioning oneself behind or to the side of a target, where they are more vulnerable to attacks and where the attacker is in a relatively safer position. A flanking attack is one made from a flanking position.
- Serpent's Strike (sword) — Do an evasive roll around your target, striking them and poisoning them.
- Death Blossom (dagger+dagger) — Do an evasive attack over your opponent, striking nearby enemies three times. Each hit causes bleeding.
- Flanking Strike (sword+dagger) — Evade and stab your foe.
- Flanking Dive (spear) — Evade your foe and then strike, dealling increased damage from the side or behind.
