I can't understand why Guidance is popular but not Resistance. It seems like saves come up more than ability checks. Am I missing something? Guidance works on skill checks?
Shocking Grasp - kinda weak for your needs, but sometimes a get-out-of-melee free spell
Aye. The rules consider a "skill check" to be an ability check you added your proficiency bonus to.
Guidance is one of the strongest cantrips. On par with Eldritch Blast (but obviously in the exploration and social pillars, not combat).For their Book of Shadows, I should clarify.
I was thinking Guidance, Message and Resistance. Any other opinions?
