i may be a cc pro but .... how do you summon?

[Masamune·1600]

I played through the game and only got 1-2 of each of those. Is there an easier way to 'farm' those items somewhere in the game?

Yes. Shiny items can be acquired in bulk through repeated summonings. Specifically, you will receive one Shiny item for every enemy defeated by the Summon. The items correspond to Element as follows:

White: Shiny Salt
Black: Shiny Soot
Red: Shiny Ember
Blue: Shiny Dew
Green: Shiny Leaf
Yellow: Shiny Sand

Thus, if you defeat two enemies with Saints (a White Element Summon), you will receive two Shiny Salts after battle.
