Equipment Issues of a Noob.

Having a few issues on Unite that I believe are being caused by my choice of equipment, but mainly the weapon. Currently, I am stuck on the Four Horns quest (both the Diablos and Black Diablos. Yeah. I'm stuck on a 4* elder quest...I suck.). The main issue is time running out, so I believe that I'm not doing enough damage.

My current equipment is:
-Rathian Helm (gemmed with an Attack jewel)
-Rathalos Soul Mail (Strength jewel)
-Tigrex Vambraces (Two Strength jewels)
-Rathalos Soul Coil (Strength and Attack jewels)
-Rathalos Soul Greaves (Two Strength jewels)
-Black Katana Mk.II (Attack jewel)

Basically, my current skills include a Health +30 and Attack Up small. What part of my lineup should I change? If at all.

I appreciate any opinion and/or help.

I would suggest chaging the weapon... Although Black Katana has great raw power for it's level and positive affinity , for the Diabloses I would suggest using the Eager Cleaver as it has pretty good raw and it has a good starting lightning element .... Plus , its' final form is one of the best longswords in the game...

Diablos is weak to and then .


Also maybe you need to prep a little better for them. Try reading about them on the wiki , as it has some really great tips .


So , take Sonic bombs to use when diablos is underground , take many potions and learn to read its' attacks...

I ended up taking another shot at them, but gemming my armor for an Attack Large, with a meat/veggies combo from my kitchen...finished the quest with 6 minutes to spare and no healing items left...only collapsed once.
