Blades of Steel

Usage Notes
If you are going for a high-energy-usage build using dagger skills that does not use the Golden Phoenix Strike, Horns of the Ox, Falling Spider combo, this is close to ideal. When used in a chain with Black Mantis Thrust, Jungle Strike, Horns of the Ox, Falling Spider, and finish with Blades of Steel, this skill can deal up to about 140 damage to casters. Instead of having very high critical strikes, you can put some points into Shadow Arts for damage mitagation and use this instead of Twisting Fangs. Blades of Steel nicely combines low Energy usage with high Damage output, but lacks a Condition effect like some Dual Attacks.

Trivia
This skill might be refering to the popular game on the original NES and one of its hockey games, Blades of Steel.
