Rulings:

• 6/23/2020 To determine the total cost of a spell, start with the mana cost or alternative cost you’re paying, add any cost increases, then apply any cost reductions (such as that of Volcanic Salvo). The converted mana cost of the spell remains unchanged, no matter what the total cost to cast it was.
• 6/23/2020 The cost reduction applies only to generic mana in the cost of Volcanic Salvo. It can’t reduce the <img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" /> requirement.
• 6/23/2020 Once you begin to cast Volcanic Salvo, players can’t take other actions until you’ve finished casting it. Notably, they can’t try to change the total power of your creatures.
• 6/23/2020 The total cost to cast Volcanic Salvo is locked in before you pay that cost. For example, if you control three 2/2 creatures, including one you can sacrifice to add <img src="/Handlers/Image.ashx?size=small&amp;name=C&amp;type=symbol" alt="Colorless" align="absbottom" /> to your mana pool, the total cost is <img src="/Handlers/Image.ashx?size=small&amp;name=4&amp;type=symbol" alt="4" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" />. Then you can sacrifice the creature when you activate mana abilities just before paying the cost.
• 6/23/2020 If a creature’s power is somehow less than 0, it subtracts from the total power of your other creatures. If the total power of your creatures is 0 or less, the cost remains <img src="/Handlers/Image.ashx?size=small&amp;name=10&amp;type=symbol" alt="10" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" />.
• 6/23/2020 You can’t target the same creature or planeswalker twice with Volcanic Salvo to deal 12 damage to it.
