Can you tell me the rulings for Helga, Skittish Seer?

0. Helga’s last ability is a mana ability. It doesn’t use the stack and can’t be responded to.
1. If a spell has {X} in its mana cost, use the value chosen for that X to determine the mana value of that spell.
2. If you spend the mana added by Helga’s last ability on a creature spell with {X} in its mana cost, the mana can be spent on any part of that spell’s total cost. You’re not limited to spending it only on the {X} part.
3. You don’t have to spend all the mana added by Helga’s last ability on the same spell.
