Hello there,
This is so-called StatStick for your Warframe, as it increase your mobility.
- Evolution I : Incarnon Form - Reach 5x Combo and then Heavy Attack to activate Incarnon Form. +3 Range, +40% Attack Speed.
- Evolution II: Drifting Grace - additional +20% Sprint Speed, +20% Slide.
- Evolution III: Shockwave Synergy - for each enemy hit by Slam radius, gain 4 Combo Count.
- Evolution IV: Evolved Ascension - +30% Parkour Velocity.
- Evolution V: Universal Readiness - collecting ammo grants 5 Melee Combo counter.
As you can see, this is not regular melee build, kind of it is, but at the same time not quite so standard.
The evolutions themselves contribute a lot here, but also the newest system of heavy attacks - Tennokai, opens new ways to use the mechanics we already know. All this gathered together in one place gives us a powerful kick... to gain momentum :D
Enjoy!
