Narga S Armor is the first armor with Evade Distance Up available in MHFU. Combined with Constitution +2 and the 8 remaining slots (after using 1 Attack Jewel to get rid of the Attack Down S) make it very customizable and useful for weapons that lack guard and use a lot of stamina, like the Hammer and the Dual Swords. With 2 weapon slots, it is possible to gem in any skill (you will generally get a negative skill from the 10 jewels though) except Attack Up. Most notably are the always useful Sharpness +1, Sharp Sword and Reckless Abandon +1, but other skills like Focus and Runner can be useful for GS, DS and Hammers. Gemming in Guard +2 or Guard Inc can make this a decent lancing set, while Defense +20 can be gemmed in without weapon slots, making this armor more resilient and suited for early G-Rank. This armor is also quite easy to obtain, though the Narga Brainstem and the 11 Black Narga Pelts can be difficult, the former because it is Narga's rarest drop and the latter because you generally get only 1-2 Black Narga Pelts per run.
With 9 slots you can add one attack jewel to get rid of the attack down, and use the remaining 8 slots with Dodge Jewels. The stats that you will have are Evade distance up, Constitution +2, and Evade +1.
The only hard part about the Jewels are the Lrg Lobstershells. you can obtain them by sending Trenya to the Jungle for 1000 points or you can fight a High/G-Rank Plesioth
