| 2-6 | 5 Units of Mana / 5 Magic Density | The effects of all spells are halved so half spell damage, duration etc. Casting time and and Magic Material costs are doubled. However you can't critically fail and gain advantage on concentration saves. |

| 16-20 | 20 Units of Mana / 20 Magic Density | The effects of all spells are doubled so double spell damage, duration etc. Casting time and and Magic Material costs are halved. However you also need to roll on the action magic surge table every time a spell is used. You can also critically fail on a 2 and gain disadvantage on concentration. |
