How to play it

Any monster

Counter everything: Foresight Slash and the other perfect-evade moves trigger Adrenaline Rush, so every successful counter is followed by +15 attack. Keep breaking wounds for Decimator heals and keep Quick Sheathe 3 for Special Sheathe. NinoMMO's advice at this point: start upgrading your High Rank armor, because monsters hit harder from here on.

Synergies

Why each skill is in the set

Adrenaline Rush
Adrenaline Rush 2 on counters
Rathalos Coil α carries Adrenaline Rush 2: +15 attack for a while after a perfectly timed evade. On Long Sword the counters count, so Foresight Slash and similar moves keep the buff up.
Critical BoostAttack Boost
Rathalos blade: fire and Critical Boost 3
Wyvern Blade "Blood" I has 290 fire, 10% affinity and Critical Boost 3, so every crit hits harder. An Attack Jewel II and an Attack Jewel add Attack Boost 3.
Decimator I2 ptsFlayerBurst
Decimator and Flayer carry over
The Guardian Arkveld helm and mail stay for Decimator I (health back when you destroy a wound) and Flayer 2. G. Ebony Braces keep a point of Burst, and three Protection jewels give Divine Blessing 3.
