[MHW] Spin to Win Hammer Build - Make your own and Solo Nergigente with ease

Nergigente was a huge problem for a lot of players to kill at the beginning, I created this build with the little resources i had on hand and was able to farm him very efficiently. (I have the Nergigente armor after farming him with the original build)

Nergigente is always found in the same area surrounded by slopes and pillars, with a Hammer you can do a slide or run up the pillar to execute the Aerial Spin attack. Since this attack is fast to pull off and does several hits, I focused my build around the attack to abuse it against this monster.

First the bread and butter of this build
Affinity Sliding -- Level 1: Increases affinity by 30% for a short time after sliding.
This is insanely powerful. Normally to get 30% affinity you need Crit level 7 which takes a lot of resources.
The easiest way to get this is to craft Kestodon Guards.

Kestodon Guards Alpha - Rarity 5
Affinity Sliding +1
Focus +1
Materials : Kestodon Carapace x6, Kestodon Scalp x3, Quality Bone x3

Next Important skill is
Weakness Exploit -- Level 1/2/3 : Attacks that hit weak spots have 15/30/50% increased affinity.
I would love to have a level 3 Weakness Exploit but decorations are rare so, And this is actually a really cheap build to get. But a level 2 one is pretty good combined with Affinity Sliding we'll have 60% chance to crit. This is also really easy to get too you can craft Dragonking Eyepatch Alpha for it.

Dragonking Eyepatch Alpha - Rarity 8
Weakness Exploit +2
3 Slot
Materials: Dragonvein Crystal x2, High Commendation x1, Immortal Dragonscale x6

And honestly these 2 skills are all you need to start off this build, everything else just compliments it. More Attack, more Affinity, more survival skills. Whatever your resources allows.
Here's a few suggestions from me.

Airborn -- Level 1: Jumping Attack power +10%
Agitator -- Level 1/2/3/4/5: While active, grants attack +4/8/12/16/20 and increases affinity by 3/6/9/12/15%
Critical Boost -- Level 1/2/3: Increases damage dealt by critical hits by 30/35/40%
Critical Eye -- Level 1/2/3/4/5/6/7: Affinity +3/6/10/15/20/25/30%
Divine Blessing -- Level 1/2/3: A chance to reduces damage taken by 15/30/50%
Earplugs -- Level 1/2/3/4/5: Reduces/Nullifies Monster roars
Heroics -- Level 1/2/3/4/5: While active, increases attack power by 5/10/15/20/30% and increases defense by 15/20/25/30/40
Maximum Might -- Level 1/2/3: While stamina is full, increases affinity by 10/20/30%
