Can I cast a spell and then have it traded to another investigator to cast that round?
This would work great with Blessing of Isis to ensure blessings all around.
Some spells say "once a round you may etc" so my thinking is that these cannot be cast more than once, but the wording literally could still mean each investigator can cast it once per round right?
After all, it would seem like they are meant to keep an investigator from preventing healing or stamina loss from all attacks all the time, which is sensible.
Passing it to another to cast once themselves sounds like a reasonable ruling.
Is there an official ruling?
