Can an investigator in an Other World secure a die on a spell, or have another investigator cast a spell for them?

Question

Accepted Answer

Yes to both. A restriction on using a spell stops only its activation, not securing dice on it, and an investigator outside the Other World can cast a spell that secures a die for one inside.
