Armour

Can someone please give me some suggestions as to what armour I should use to fight the nekoht urgent narga, as my rath soul armour isn't quite cutting it, cheers for all suggestions

I have only got the rath soul normal, didn't know there was a U version?

I've upgraded the soul normal to the start of where I need royal armour spheres and I haven't got the mining point or know which area to get them, and I'm working one getting my eager cleaver upgraded just need a Kirin quest to appear again

Uncle Sam, you should at least check first if you want to give advice. Rath Soul U can only be made at 9 star, which means you need to kill narga first before you can get it.

Now for armor, I will recommend Orbituary/Butterfly armor for evade+ OR Ceanataur S for damage skills
if you want to fight easier, then grab that evade+ set, but f you want to get faster kill, Cean S is better (also a good armor to go to G-Rank)

the highest damage output to narga at that point of the game will be Cean S with Lion Emperor Saber. But I'm not going to advice you to make it, because you will need to farm for it (takes too much time, and it stop upgrading at that point. it's not worth the effort). TDS will be a good choice, so try to get that instead

Just like Gnx suggested go for Ceanataur S as its prob one of best sets in midle game.Personaly i prefer ceanataur U over S ,as i think its one of the most flexible sets out there (can get pretty much any skill you want with litle bit mixing and decorating.From ra+3 to high grade earplug) , but thats just me.Most people go for Cenataur S allso these sets are pretty easy to obtain because of multiple ceanatur quest GL

Ceanataur S gives S+1 ,shaperning inc,and attk med if i remember correct?Ceantaur U decorated for S+1 gives
S+1 ,Sharp sword,Ra+1 and some negative skill (cant remember i think its bad luck and health decrease).However its hard to get the Artisan decoration thats why i agreed with you That Ceantaur S would be most peoples choice.
