[RPG] How to a Sorcerer/Warlock use 4 Eldritch blasts in one round


How is it possible for the infamous Sorlock multiclass to use 4 x Eldritch blasts in 1 round?

I get the extra damages as in the d6s and +mod damage from all the curses but I see formulas around like 4d10+4d6+64 (aasimar build), then 8d10+8d6+108.

How is this possible?

You don't need to be a Sorlock to create four eldritch blast beams in a round

Eldritch blast is a cantrip and all cantrips increase in damage as the PC levels. Eldritch blast, however, is pretty unique, in that rather than simply increasing in damage, at higher levels the caster instead fires additional beams, which all roll to hit and damage separately:

The spell creates more than one beam when you reach higher levels: two beams at 5th level, three beams at 11th level, and four beams at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.

So, any 17th level caster that knows eldritch blast will create four separate beams, whenever they cast eldritch blast (note: cantrips scale with total character level and not individual class level - so multi-classing won't delay cantrip upgrades).

So what does multi-classing to Sorcerer add to the mix?

Sorcerers have the feature Meta-magic, from which they can choose to use Quickened Spell:

When you cast a spell that has a casting time of 1 action, you can spend 2 sorcery points to change the casting time to 1 bonus action for this casting.

This means that a level 17 Sorlock (or a Sorcerer that knows Eldritch Blast by any other means), can spend 2 sorcery points in order to cast Eldritch Blast with both their action (as normal) and also their bonus action.

Four beams of Eldritch Blast for their action and another four beams for their bonus action equals eight beams in total. Blast off!

Side note: A Sorlock could actually get four beams in a round as early as level five using quickened spell (Sorcerer 3 / Warlock 2 if you want to benefit from agonizing blast too) - though they'd only have enough sorcery points be able to do that once a day without burning spell slots.
