-Book of Sefer Raziel (different from Merlin's book which is a joke in comparison; this book literally grants the power of God).
-Flute of Krishna (instant multiversal destruction/creation - also power of God)
-Materioptikon (housing a part of dream's power capable of creating billions of realities)
-Soulfire formula (able to defeat the Source)
-genesis box (instant universal destruction/recreation)
-Darkseid had some kind of device which taps into the source and was able to freeze Ares w/multiversal godwave. This also reminds of the time where Inertia build a device which absorbed the entire Speed force but oddly enough was said to be able to only destroy the continent even though it's supposed to be at least universal level (note that this was the only time that the entire SF was concentrated inside one place/object).
-some new gods tech was able to destroy the shadow oblivion entity which was destroying the meta-verse.
-cosmic cartridge (NG tech capable of making one aware of everything in the universe instantly)
-the heart of the universe/nucleus core featured in old GL comics (absolute universal control)
-Holy Grail (similar to spear of destiny)
-silver twist (object capable of creating realities with thoughts)
-Ubx's stick (capable of withstanding multiversal nullification)
-Dragon God scepter fragments (grants power at least on par with the spectre).
