They're Epic Spells. Make your own.

Uh anything your spell can do, alter reality can do and more!
If you're twinking and you ain't got some divine ranks, you're doing it wrong.

Ever seen Slayers SMB? Giga Slave summons the Dark Lord of all Dark Lords, the Golden Lord of Nightmares from her plane of existence; The Sea of Chaos. With just a thought, she can destroy all creation just on a whim.

Also, Lord-sama is also the creator of all the Gods in Slayers canon as well so she is literally both God and Devil. ^_^

Can your Alter Reality do that?

I'd screw it up and make it too OPed. Though the point of the Dragon Slave is pure overkill...

That's not really a spell now is it?

Watch the videos on Youtube and let her explain it herself. After all, she is the Mother of All Darkness who has dreamed years uncounted of regaining her form. Also, power is her mind and her mind is her power; when uncorrupted by other elements, her mind becomes her purest power.

The spell basically kills what which can't be killed as nothing is more powerful than Lord-sama.

There are Arcane spells that do draw power from dieties. This is just taking that to a different level altogether.

No you see that is some kind of innate power she possesses. Spells can be learnt by everybody.
Also spells follow rules and are inherent from somewhere. If it's just |I can do it cause I'm special not really a spell.

Okay let me explain it than for you SMB.

Most spells in Slayers draw power from somewhere. In the case of White/Holy Magic, it's the Gods(Shinzoku) or the Astral Plane (spell dependant). Shamanism draws from the Astral entirely.

Black Magic draws from the Demons/Monsters(Mazoku). The most powerful spell in this block is Dragon Slave, which draws power from Ruby Eye Shabranigdo, The Demon King of the Monsters.

Spells like the Ragna Blade and Giga Slave however draw power from the Lord of Nightmares and are hence, different and defy classification. Literal Entropy unleashed. There is a hint that Fusion Magic (Holy+Black) is a form of Chaos power.

Furthermore, Giga Slave is the mind of the Lord of Nightmares too. The caster has to do a kind of check when casting the Giga Slave or it goes out of control and Lord-sama takes over their body, swallowing their soul/conciousness in a tide of darkness deeper than the deepest night. Lord-Sama is than free to do what she wants...which isn't a good thing.

So technically, the Giga Slave is both Divine and Arcane magic as it draws into our existence the mind and power of a being who is both the God and Devil.

Does that make sense now? Lina doesn't use it much due to how dangerous the spell is. Furthermore, I don't see her ever teaching that spell to anyone unless she knew they would only use it in the worst of situations i.e. Elder Evil unleashed and nothing else can stop it.

And get spilled phlogiston and bits of crystals all over the Ethereal Plane? You'll never be able to get all of the shards out and someone's going to cut their foot eventually.

Prime Material Plane is over-rated anyways!:dance:

GM'ing
 

Actually, this can be done in 3.5 Edition. I've run the simulations and math. It's called an instantaneous infinite damage loop + instant annihilation via a minor (4th level) trick of magic items. Technically, it's only for a particular target, but if you have an infinite number of consecutive turns (without interruption), and an infinite reach, you can do that to all of reality in literally no time, although to you it'd be a successive series of attacks.

ALTernatively, you could just play a 5th level kobold...

ALSO, if you really want that spell badly enough... it's epic magic:create it. Your application of what does and does not work as epic spells isn't true in the slightest. A high enough HD character (roughly 300-or-so) can actually get infinite-range all-consuming spells of limitless power by themselves. Run your own game set in that universe and simply have an epic spell that's insta-kill whatever. Heck, roughly 30-to-40 HD characters can set up epics that allow them to insta-level (within certain limits, "insta-leveling" is kind of a misnomer, as it's more like a year to accomplish), so they can get that 300 HD without too much of a fuss or difficulty.

And... you can always simply take the principles behind the Lina Inverse reality and apply it to your own campaigns. The distinction between divine and arcane would still remain - academically - and even those that "defy classification" can have a label applied (ex: "wild magic" or "chaos magic" or even "classification-defying-magic", the last of which, means, ironically enough, that it's not classification-defying, thus making it a misnomer). Even in Forgotten Realms [3.5] arcane magic is just a form of divine magic that adheres to Mystryl's/Mystra's(/Midnight's) rules of behavior. Nullification stuff and entropy is simply variants of Spheres of Annihilation. So, you can really have it both ways.

FURTHER, if you want it to be available for characters who aren't 300-some-odd HD, you can simply allow them limited access to it (or give compelling plot reason, such as Lina has, to limit its use themselves). This actually fits in quite well with epic magic and it's problems and draw-backs, for lower-level characters.

So, yeah, just make your own!

Agh! Second-Edition! The horror! The unmitigated horror!
