#lvl 20

Well... After some research, we’ve found 2 methods to become a god as quickly as possible.

METHOD ONE: Just Wait...

According to This Reddit Post by DeathMcGunz, trusting that the math is accurate, it suggests that any player could become LVL 20 in as little as 36 Days...

And, according to the Dungeon Masters Guide:

The DMG includes suggestions for character advancement past the level 20 mark. This is the Epic Boons section on pages 231. 

The gist of it is that for every 30,000 XP a character earns past level 20, they receive an epic boon. 

And, according to the table,  a player at level 20, after 36 days of adventuring, is expected to gain 40,000 XP per ADVENTURING DAY!

And since we only need 30,000 XP to get an Epic Boon, then this means that for each new day of being at LVL 20, you can get a new Epic Boon.

And with only 26 Epic Boons in the DMG for 5e, then that means you need 780,000 XP to get all of them.

Or roughly around 20 Adventuring Days to earn.

Which means that in 56 Days, you’ve become LVL 20 and have earned all the available Epic Boons

And with the “Epic Boon of Immortality” also being available, you can get that too!

And since a “God” is defined as:

“An immortal being with powers over nature, fate or fortune.”

Then by being a LVL 20+ Druid or Spellcaster, with powers over nature, and with a Racial Trait, a Feat or a Spell that can allow you to re-roll a dice, effecting changing the result and therefore the outcome and fortune of the player...

You get where I’m going...

And this combined with the “Epic Boon of Immortality”, would mean that you would be an immortal being with powers over nature, fate or fortune.

Therefore... Technically... You become a god...!

OR... YOU COULD USE METHOD TWO!

METHOD TWO: STEAL THE DIVINE SPARK

This one requires more than just waiting...

It requires that the players is a high enough level in the right class to know the Plane Shift Spell.

Then, simply use the spell to go over to the Astral Plane...

Visitors to the Astral Plane occasionally stumble upon the petrified corpses of a dead god or goddess, or other chunks of rock drifting forever in the silvery void.

Now, before moving on, this part may not always be Lore in your D&D World, but it is in many:

In many D&D pages of Lore, a dead god is rarely completely dead, just mostly dead.

Another deity (or mortal which will become a deity) is able to steal the essence or divine nature of a deity that is “Mostly Dead” when they are on the Astral Plane, or some similar thing happens causing the essence to be stolen.

Stealing the “Divine Essence” of a God or Goddess that floats on the Astral Plane means that you are stealing what makes them divine and using that on yourself, effectively turning you into the god from which you stole the Divine Spark.

Now, this method is a lot more to do with how your DM sees gods, and how much they follow D&D Lore.

If they are flexible, they may allow it...

If not, then there is always Method One.

But, there you have it!
