@AntiSocial_PhilRuling Needed. Pact of Tome grants other classes cantrips as warlock cantrips using warlock spellcasting ability? The intent of Pact of the Tome is that the chosen cantrips become warlock spells with Cha. as the spellcasting ability.

@Uriah_StonePHB 203 all magic works the same way through study or deity, could a wizard pay to learn other spells from another class list? since spells of level x are balanced against each other, should be fine. Can cause wiz to step on other classes, if you care.
