Wild Magic Surges may only trigger after casting a sorcerer spell of 1st level or higher. By default, sorcerers cannot cast spells as rituals, but if they take the Ritual Caster feat, they can (for the list of a chosen class, including sorcerer).
My question is : provided that a Wild Mage takes the Ritual Caster feat with the sorcerer class option (there are 4 sorcerer rituals in total : Detect Magic, Comprehend Languages, Water Breathing and Water Walk), can he then trigger Wild Magic Surges upon casting either of these 4 spells as a ritual ?
