Does a wizard have to have the spell prepared in order to cast it as a ritual?
For example, Gnickel wants to cast Tiny Hut at the end of a day of adventuring so the group has a more comfortable place to rest at night. Does he have to spend an hour exchanging his prepared Lightning Bolt to memorize Tiny Hut, then cast TIny Hut as a ritual (taking 30 min), then spend another hour to swap Tiny Hut back to Lightning Bolt?
Not sure if we addressed this. I envisioned rituals to be more like a wizard reading directly from a spell book, so I’d vote that it does not need to be prepared in a traditional sense as long as the caster is in possession of a written version of the spell.
Should also consider adding a focus cost to ritual spells in addition to any other material costs. That would be for things like arcanic tools, exotic materials, etc that are necessary to turn a normal spell into a ritual. Maybe call it a kit that costs 100*(spell level)2 gc.
