Empowered Spell låter dig rerollera ett antal tärningar; det ger ingen specifikation om tärningen.
When you roll damage for a spell, you can spend 1 sorcery point to reroll a number of the damage dice up to your Charisma modifier (minimum of one). You must use the new rolls.
Jämför med Great Weapon Fighting , som uttryckligen uppmanar värdena du kommer att reroll.
When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2.
