Learned a skill but cannot use it? Day-night builds and ability slots

Separate manuals, training, equipped abilities, charge capacity, and armour proficiency before spending more points.

If you spent points at a shrine but still cannot use the ability, do not immediately buy another skill. Check read, learned, equipped, valid form, sufficient resources in that order.

Do not assume every Witchcraft passive is day-only just because its active spells are. Read the Anytime text and sun/moon icons on each node.
