Spell Check
When you cast a spell, you now always roll a Spell check that determines the forcefulness of the spell in question. The higher the roll, the more likely it is to be effective, and the harder it is to counterspell or dispel.
Spell Check: When you cast a spell, you roll a D20 Test and add your spellcasting ability modifier. If you use a Spellcasting Focus that is associated with the school of the spell to cast the spell, you also add your Proficiency Bonus.
Determines Forcefulness: When a caster tries to counterspell or dispel a spell you cast, they have to beat the Spell check to succeed.
Replaces Spell Save DC: When you cast a spell that requires its targets to roll one or multiple saving throws, the DC is now equal to the Spell check minus 2 instead. If the spell affects more than one target, the DC is reduced by another 2.
Merges Into Singular Spell Attacks: When you cast a spell that requires you to make one attack roll, the Spell check and the attack roll merge into one roll that counts both as the spells Spell check and a spell attack.
Influences Spell Multiattacks: When you cast a spell that requires you to make multiple spell attacks, roll the Spell check first. The spells attack rolls are modified depending on the Spell check result as follows:
| Spell check result | Attack roll modifier |
|---|---|
| 4 or lower | -5 |
| 5-9 | -2 |
| 10-14 | +0 |
| 15-19 | +2 |
| 20 or higher | +5 |
Additionally, if you roll a natural 1 on the Spell check, you roll the spell attacks with Disadvantage, and if you roll a natural 20 on the Spell check, you roll the spell attacks with Advantage.
Magic Items for Spellcasting: Where some magical items previously gave a +1 to spell attack rolls and/or a +1 to the Spell Save DC, they now give a +1 to Spell checks.
