I decided to through the Firebolt cantrip into the "Attacks and Spellcasting" box on the character sheet. I understand I use my Char modifier, but do I also apply a proficiency bonus as well to the Atk bonus? Thanks in advance.

  • \$\begingroup\$ @NeonKraken For reference, have you tried reading the DNDBeyond entry for sorcerers or the D&D 5e basic rules? Or the linked questions on this site? \$\endgroup\$ – MikeQ Aug 3 at 4:32
  • \$\begingroup\$ I've already read through the sorcerer guide. I'm not really concerned about the actual attacking process, moreso what to put on my page. \$\endgroup\$ – NeonKraken Aug 3 at 4:33
  • \$\begingroup\$ In the attack box, I am putting the "Firebolt" cantrip as on attack, so i am wondering how I calculate the attack bonus or if there is any at all. \$\endgroup\$ – NeonKraken Aug 3 at 4:33

For cantrips and other spells, both the spell save DC and spell attack modifier include proficiency bonus.

If you check the sorcerer's Spellcasting rules, it tells you how to calculate your spell save DC and your spell attack modifier.

Spell save DC = 8 + your proficiency bonus + your Charisma modifier

Spell attack modifier = your proficiency bonus + your Charisma modifier

Your character's proficiency bonus is included in both formulas.

Cantrips are spells. When you make an attack roll as part of a sorcerer spell, then it's a spell attack, so you roll a d20 and add your Spell attack modifier, comparing the total versus their AC. However, the proficiency bonus is not usually included in damage rolls.

Similarly, if a sorcerer spell requires the target to make a saving throw, then the target would roll their saving throw (d20 + some modifiers) against your spell save DC.
