So I was reading the new preview: Let's Shake on It, when something caught my eye:
In addition, Dark Pacts also act as great boons for spell-casters. Any time an investigator attempts to cast a spell, they may reduce the sanity cost of the spell to 0 and automatically succeed by taking a Dark Pact card.
Really? Reduce the sanity cost to 0 and automatically succeed? I guess all the bitching and griping about Call Ancient One with the Crystal of the Elder Things didn't sink in. I'm enforcing the rule that you can't cast a spell with a higher cost than the sanity you possess, regardless of your ability to negate it all (as if I didn't before). This is getting ridiculous.
