Ral, Storm Conduit

The copies that Ral's last ability creates are created on the stack, so they're not "cast." Abilities that trigger when a player casts a spell won't trigger.

If the spell that's copied has damage divided as it was cast, the division can't be changed (although the targets receiving that damage still can). The same is true of spells that distribute counters.

You can't choose to pay any additional costs for the copy created by Ral's last ability. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too.
