Hopefully the LAST 5e game I'll ever play!
My character used Glyph of Warding and Simulacra to abuse the action-bonus-action mechanics of 5e to destroy the multiverse and smuggled the extant multiverse into the new empty one, rather than let it all die a slow, unwinnable death at the hands of an entity that was, ultimately, Entropy-With-Teeth-And-More-Strings-Attached.
We crossed the span of the multiverse in a single action, causing the Vile Cascade to respond by destroying the whole thing, as we successfully violated one of the few actually sacrosanct multiversal constants: speed. This caused the great collapse of the multiverse, and restarted it in a blank, cascade-less, pristine starting state, pre-big bang style.
My character then, using all the power of time and space, but also the unique power of having existed in a previous multiverse, created a portal connection between this multiverse and the multiverse that existed in their specific personal pasts; not simply creating a copy, but bringing over every particle, one-for-one, of the old multiverse, except for the parts they didn't want - like the Vile Cascade (and the idea of Rampancy - gods going mad, etc.)
In doing so, my character also did the sneaky, and changed how the fundamental physics of this multiverse works - no more infinite Simulacra, no more Rampancy, no more weird power scales.
No more action bonus action flow of time. Now, 3 actions. Time was no longer divisible by 6.5.
He changed the whole multiverse to Pathfinder 2e.
Everything is as it ever was, no one was ever even aware of a problem in the first place. Trillions of universes and all their lost souls, now restored, in addition to those that had survived. The axis of Law, Chaos, Good, Evil - all torn down. The only multiversal constants are Max Speed and Normal Entropy; everything else is shaped by their interactions.
Which were, of course, carefully guided by the extant infinite quantity of my character, silently and cautiously ensuring the multiverse is exactly as it was, down to the particle, before simply letting it continue as before.
They did it themselves - they did it right, and watched the sun rise on a grateful multiverse.
Thus ends the tale of the Wildbreakers. My longest, greatest TTRPG campaign ever, at 6 years running. Fully finished, level 20 + godhood.
My advice?
Don't bother with 5e. It's genuinely a shit system. PF2e is better. Great campaign, truly in spite of its ruleset.
