Need Help Understanding Icons in Build Mode

[DankyMcDankpants]

Hello I'm trying to understand what some of the icons mean that show up when building a gunpla.

1. When hovering over some items it will have a section in Specs titled "Parts" and it lists some parts. What does this mean/what is it for? I don't see it on all items so I am unsure.

2. There are three pink up arrows stacked on top of each other to the right of some of the stats. I thought this was related to an increase in that stat, however I've seen instances of the stat decreasing but the pink up icon staying. What does that icon mean?

3. Skills have a "shuffle" icon. What is that related to?

The first one means that part takes up multiple part slots. As you can see, Z'gok's body is also its head.
I think your second two image links are broken, by the way.

Thanks for letting me know.

I've updated the links could you let me know if they work now?

[MechaDeka]

Yeah the links work now. The shuffle icon in the third one means that once you max out that part's rarity (stars) you can use its EX moves with any other part that has its rarity maxed.
(Example: You can use Unicorn's NT-D transformation using a Zaku torso.)

Awesome thank you for helping me with two of these! I haven’t gotten that far into the game yet so I haven’t learned about the mechanic you described.

Clarification request: are you suggesting that if you synthesize the Unicorn torso with NT-D into the Zaku torso, the remaining Zaku torso now has that option to use the now lost Unicorn's NT-D transformation EX skill, so long as both parts were at max rarity before synthesis?

because if so, neat, and excuse me while I go check and see if a few arm parts have their OP skills shuffleable...
