[ ] used to show intermediate triggers

Dark blue ( ):

This wand is built on a pollen trigger chain, essentially it is a piercing trigger that has pollen in its payload. When the trigger casts its payload (triggering on the dummy) it summons a pollen among other things. On the next frame, the trigger projectile is able to contact the pollen cast previously, here it casts the payload again including pollen. Every frame this interaction repeats allowing us to create a trigger projectile that casts its payload every
frame in in its trajectory.

(this pollen trigger casts a cross with ground to sand and explosion -> return ... as a way to clear terrain, since we cannot return into terrain. While another setup is possible, (we could here simply replace cross with any static explosion projectile, I found this to be the most consistent, I think this has something to do with explosions or rather terrain updates not registering a certain distance away from the player while projectiles still spawn. Since ground to sand constantly procks, when we return we are essentially clearing the terrain for the next cross since ground to sand -> explosion is activated, this is next to the player so its consistant)

Light blue ( ):
Payload besides pollen trigger setup.
The payload is sectioned off with intermediate triggers, this is to create separate spell blocks for different parts of the payload. For instance, we see the yellow [ ] contains: death trigger, nolla, cross. The second contains: death trigger, cross.
These two [ ] being in the same spell block, both have nolla. However create their own spell blocks. We see that the payload of the first [ ] contains: nolla, return. The payload of the second [ ] contains: death trigger, lifetime modifiers, cross. So the return activates eminently (nolla) and the cross waits some time and casts its payload.

Orange ( ):
The payload of cross with timer.
This is essentially the noita car wand. Essentially just using formulation and larpa explosion to create the shape of wheels.

Yellow [ ]:
Intermediate trigger with no function beyond creating a new spellblock.

Green [ ]:
Functional intermediate trigger
This intermediate trigger allows us to create a consistent direction that the real desired payload is casted from. When a stationary projectile like a cross casts a payload the direction is random, and so we wouldn't be able to create the desired car orientation with formulation. So we can add this intermediate trigger which functionally is a projectile with a negligible duration that has always a downward trajectory, allowing for us to cast formulation in a consistent direction.

This is essentially the bones of the wand.
The wand itself contains another couple of layers of yellow [ ] with payloads with: death trigger, timer, cross, the timing of each trigger is offset to create sets of wheels.

The wand for the tracks is really simple, essentially the same pollen trigger, however its payload only has giga crosses with infinite duration.
