Before you spend an Arrow
D4C is obtainable from Stand Arrows, according to the developer's D4C changelog. An Arrow is not a guaranteed D4C. Redeeming the D4C code gives items, not the Stand.
Check the active slot first.
- If you want to keep the Stand you have, use an empty slot when one is available. That branch comes from the community slot guide and still needs a check in the current menu.
- If the slot you would change is occupied and you want to keep that Stand, do not use a removal item on it.
- If you mean to replace it, the reported order is Rokakaka to clear the selected Stand, then a Stand Arrow for another draw.
Lead Helper notes describe Rokakaka Fruit as resetting a Stand in your Stand inventory. Select the Stand you intend to remove. Those notes do not prove that every other slot or progress field stays untouched.
Slot capacity and any paid slot should be read from your menu. Do not assume you must buy a slot before the next draw.
Where Arrows come from
A helper FAQ lists four Arrow sources:
- Craft one from Arrow Fragments.
- Take one another player drops for you.
- Use Spin Tickets on spins that can provide one.
- Pick up Arrows that spawn during a race.
None of those is a guaranteed Arrow from every spin or every race. A community wiki states that 5 Arrow Fragments craft one Stand Arrow. The helper FAQ does not give a fragment count. Open the crafting panel and read the recipe before you confirm.
The same wiki says the game chooses the Stand for you. A separate guide says a Stand Arrow offers three random choices. Those reports disagree. Compare whatever the draw actually shows, and do not plan on picking any Stand from the full roster.
A later guide says fragments can drop in Battlegrounds and as a race completion reward. Treat that as an extra reported source, not a rate.
Spin Tickets are a reported way to spin for Arrows. They are not the same thing as finishing Gyro's Spin quests.
Crafting path
The community slot guide points at Stands, then Craft, for combining fragments. The panel is the authority for the current quantity and any other cost. No fixed fragment price, drop rate, or fragment map is published here.
What an Arrow does not do
Corpse Parts are not a current obtainment path. A November 8 helper answer says they are not available yet and ties that to evolutions not being available yet. A planned Scary Monsters quest evolution is part of the Stage 3 schedule, not a live recipe.
Reported obtainment for Pin Bomber
Pin Bomber is a community name for Oyecomova's Stand, also called Tic Tac Boom in a tester reply. A direct player reply to an obtainment question was "Reroll." That is not a published odd, and it is not the Defused Pinbomb quest item used in Gyro's chain.
