Looks like Set #70503 - The Golden Dragon.
I looked up this unique modified 2x2 brick to get a short list of possible sets.
Visually, looked at the yellow/gold color scheme of the pieces in the bags to get a sense of the what to exclude when scrolling down said short list.
Looked for crazy looking pieces from the bag to compare within the set.
and double confirmed the choice with part #54821 - Bionicle Zamor Sphere (Ball).
Just gotta be the Goldy D.
