This spell is a variation of:
Kereska's Favour

Notes

The in-game tooltip for this spell says its effect inflicts Noxious Fumes for 1 turn, but it actually inflicts it for 3 turns. It also requires a  DC 13 Dexterity Saving Throw to apply the condition.
Possibly applying Noxious Fumes can only occur once per attack. A spell hitting multiple targets will still only make a single saving throw for one of the targets to apply the condition.
This is the only variant of  Kereska's Favour that requires a saving throw to inflict its condition. The ice, thunder, and poison variants all apply their respective conditions without a saving throw.
The version of  Melf's Acid Arrow granted by this spell matches the damage of a level 5 upcasted version (7d4⁠⁠Acid + 5d4⁠⁠Acid delayed), but it only counts as a level 2 spell.
