GOD RULES: Player's Guide (5e) Previews/Discussion

Random question; I have been wondering what the power level of a 20th level spell would be?

20th level spells are for when you want to affect an entire planet or things of that magntude.

ie. Blow a planet up, Control every mind on a planet, Teleport a planet, etc.

Also a planet basically approximates to a single planar layer (I know people say they are hypothetically infinite, but occupied space is typically about the same size as a planet or less).

A full PLANE would be more akin to a galaxy (in around spell levels 27-29).

As I have perviously come across homebrew that would allow for a upcasted spell of that level. And the spell preview furthered the question, as presumably they would be even crazier then the ones we've seen so far.

In terms of damage dice you are looking at around 800 @ 20th level spells.

Planets (by my rules) have around 3000 HP*, but Damage Threshold 1500*.

*If I remember correctly - might be 4000/2000.

The way I have it structured, 15th level spells are the maximum a mortal can Overcast** so you have a few crazy cult "Doomsday" scenarios (like Fimbulwinter, Radiation Zone) in those 14th & 15th level slots.

19-20th-level spells are in around your high immortal tier spells (if the immortal engages in a bit of Overcasting) so its more planetary scale effects.

**I did move Karsus Avatar (not the name in the book obviously - I use some obscure occult term) to 18th though, we can presume he was effectively a Demi-deity in terms of personal power.

Initially I was thinking the old, 10th/11th/12th level spells would be 10-11/12-13/14-15 in my system. But Volcano fits as a 16th level spell (a Super-volcano variant is 17th), so it did not feel right to have Karsus Avatar as a mere 14th-15th level spell. So as a rule of thumb each 'old-school' spell level above 9th = +1-3 spell levels in my system - needs some testing but that's probably the simplest and easiest conversion rule.
