Chameleon

A creature you touch becomes transparent until the spell ends. The target can perform a DC 10 wisdom saving throw to avoid the effects of the spell if they want. Anything the target is wearing or carrying is transparent as long as it is on the target's person. The spell ends for a target that attacks or casts a spell. If the target stays still, they reach full invisibility. If they move, consult the following roll. Using less than half of their movement speed gives a +5 to the roll.

The target must roll a d20 wisdom check. The level of transparency is determined by the roll. 1-7 the spell fizzles and fails. 8-11 you reach first level of transparency and +1 to stealth rolls. 12-15 you reach the second level of transparency and +2 to stealth rolls. 16-19 you reach the third level of transparency and +3 to stealth rolls. 20 you reach full invisibility and +4 to stealth rolls.
