Normal

When determining the powers and bonus spells granted by this domain, the druid’s effective cleric level is equal to her druid level. A druid that selects this option also receives additional domain spell slots, just like a cleric. She must prepare the spell from her domain in this slot and this spell cannot be used to cast a spell spontaneously.
