@JeremyECrawford RAI, it seems multiclassing shouldn't be terrible. RAW, due to rounding, an EK5/AT5 doesn't have 2nd lvl spells. Thoughts?

Multiclassing—this optional rule is designed to make class combinations possible, not necessarily ideal. Work with your DM to fine tune #DnD https://t.co/LaifTNNYTB
