Spell Points
Spell Slots are replaced by Spell Points and Spell Limits. These rules run roughly parallel to the variant rule in the 2014 DMG.
Spell Points: Instead of gaining a number of Spell Slots from the Spellcasting feature, you now gain a number of Spell Points that determine your Spell Point maximum. You can't have more Spell Points than your Spell Point maximum, and you can't have less than 0. Your current Spell Points are set to your Spell Point maximum when you finish a long rest, similar to Hit Points.
Using Spell Points: To cast a spell, you now spend Spell Points instead of a Spell Slot. The table below shows how a spells level is translated into its Spell Point cost.
| Spell level | Spell Point cost |
|---|---|
| 0 (cantrips) | 0 |
| 1 | 3 |
| 2 | 6 |
| 3 | 9 |
| 4 | 12 |
| 5 | 15 |
| 6 | 18 |
| 7 | 21 |
| 8 | 24 |
| 9 | 27 |
| x | 3x |
The Spell Point cost, as you might notice, is equal to three times its level. This is only the initial cost, as the final cost can be increased through upcasting and reduced through a few features. When these rules speak of a spells Spell Point cost, they refer to the initial cost, and they speak of casting costs when the final cost is intended.
Other Features using Spell Slots: Some features that are not spells make use of Spell Slots regardless. These features now also use Spell Points instead, with the Spell Point amounts that they can use being multiples of three, similar to the conversion of Spell Slots to Spell Points otherwise.
