Forbidden Flame Additional Information
- Sorcerer's Apprentice will not grant you an extra mana. Forbidden Flame spends what’s left of your mana. Apprentice will, however, reduce the cost of the card if it was increased by something like Loatheb. [Source]
- You can only have 10-mana so the maximum mana you can spend is 10. [Source]
- You can cast Forbidden Flame even if you have no Mana. This means if you have Malygos on board you can do 5-damage (from Spell Damage) for 0-mana. [Source]
