In DnD 5e, spell attack bonuses are added to the d20 roll when making a spell attack. The spell description determines which dice to roll for the attack roll, and the spellcasting ability modifier (based on Charisma, Intelligence, or Wisdom) is used to determine if the target needs to make a spell attack or not. Intelligence is used whenever a spell refers to your spellcasting ability and when setting the saving throw DC for a spell.
The spellcasting ability modifier (which is either Intelligence, Charisma, or Wisdom, depending on their class) is used to calculate the spell attack bonus. Most spells require attack rolls, and when executing such a spell, a 20-sided die (a d20) is rolled, adds the Spell Attack Bonus to the outcome, and matches it against the target’s Armor Class (AC). If the total meets or surpasses their AC, the spell attack bonus is calculated using their spellcasting ability modifier.
For attacking spells like Firebolt or Ray of Frost, the spell attack is just the modifier (for a wizard using their intellect) and their proficiency bonus. For example, if a wizard has a +3 proficiency and +3 modifier, their spell attack bonus is a +6. However, most spells have no damage bonus unless you get a feat or special ability from your class.
The attack modifier is used when making the attack roll, which determines if your spell attack hits. The Spell Attack Bonus is your relevant spellcaster modifier (Intelligence) plus your Proficiency Bonus (PB), which is not applied to damage. The spell attack modifier is your spellcasting ability modifier (depending on which ability your class uses) plus your proficiency bonus.
Clerics, druids, and rangers use their Wisdom (WIS) modifier to cast spells, so their spell attack bonus is WIS modifier + Proficiency. Bards, warlocks, and other characters can also add a bonus to spell save when using a spell attack in DnD 5e.

Spells are discrete magical effects that shape the energies that suffuse the multiverse into a specific, limited expression.

The attack bonus with a spell attack equals the spellcasting ability modifier + your proficiency bonus.
Most spells that require attack rolls involve ranged attacks. Spell casting rules vary among character classes and monsters, but they follow the same rules. In most cases, the desired effect is unleashed within seconds.

Spell attacks generally have a higher success rate than spells with saving throws, as they target a single defense (Armor Class), making them more reliable in landing hits.
