Item Completion help

Alright, kids.
I don't care if this has been done before, but, I need help.
Specifically, in locating 27 items in the Item Completion Event after beating the game.
The items are as follows:
Items: Completly owned, nothing left
Key Items: See above.
Armors: Leg-Ultra Solleret
Arm- Sacred Guard, Aqua Hands,and Inferno Gloves
Body-Quakebeast Fur
Weapons: Twin Blade- Baian, Miracle Twin
Blademaster-Godslayer, Gold Swore, Trickster, Saturn Soward, Mecury Sword, Mars Sword, Phantom Pain, SkySweeper, Rugrats NIghts.
Heavy Axe=-Gaia's axe, Neptune, Vampire Axe, Crazy axe, Lighting axe, Dimension.
Long arm-Madlance, Gungir
Wavemaster-Wand of Dreams, Awful Stun Rod.

There you go, any one of those will do.
A location, a creature, anything, I'm good.

A hunt worth taking on. but there is no way to collect every single rare Armour and weppon throught out every game is there?

I was talking about every single item that had RARE slapped onto it

and that we shall! do you like you little collection so far?

I know

you dont always get those item from the gott status. you have to keep going back untill you get what you want.

btw the links i gave and what i said should get you all those items you need.

I need the heavy blade weapon excalibur. I've heard the only way to get it is to trade with kazu but that ended up being given to Blackrose and now I dont have it to register it. Is there another way to get it? or am I screwed.
