At will (cantrip) casting.

[Ras K'cir]

A grab bag of questions about the At-will aspect of cantrips for the witchwarper:

Fatigue:
The duration of the fatigue is one round/level. Can the caster use the at-will casting to designate additional fatigued enemies, so that in principle at some point there could be <caster level> enemies all simultaneously fatigued (assuming they all failed the laughably easy fortitude save).

Detect Magic: Given that the duration is concentration, and it can be recast at will, does the 1 minute/level limitation have any meaning?

Token Spell: This has a duration one hour. There is no statement about the need for continuous concentration for the activity to persist. Can the caster move away from the action, once begun, and have it continue, or is the caster tied to within 10' of the activity for its duration? OR if this a "Set and Forget" kind of effect, then does the At-Will aspect allow the caster to create additional instances of the token every round? (This could have the effect of SIGNIFICANTLY speeding up any cleanup effort etc if you have an army of 600 instances at your command).

Charming Veneer: Again the duration is 10 minutes. Does the At-will aspect allow the caster to move about a crowd and conferring the veneer on as many as 100 creatures?

Also we don't have any discussion of verbal/somatic/material requirements so important for D&D/Pathfinder castings. Are these silent effects unnoticeable by any casual observer, other than the strangeness of the caster moving around touching individuals. ("Personal Space!") Or is this an un-disguise-able weird muttering and waving of appendages that suggests arcane forces or the need to call social services?

Spells in Pathfinder, Starfinder, and in Pathfinder 2e all have visual manifestations that show that you are casting. Which is what all the glowy stuff is when people are casting spells in the art.

Not sure what you mean by "designate additional fatigued enemies", but each fatigue casting only targets 1 creature, with no cap on how many you can have at any one time.

Detect Magic's duration would mainly just matter for if you get 1/day uses of the spell from an option or if it's in a consumable item.

Token spell doesn't create activities. It makes it so you can do all of those things whenever you desire during the duration. Changing the colour of something or making a thing clean doesn't require more then 1 turn.

Charming Veneer can do that yes.
