Dark Sun

[shadowoflameth]

So I've been picking up on the rumor that one of two settings to be coming up from Wizards may be Dark Sun. I have some ideas for a story line. If the setting does not appear soon though, what suggestions might anyone have for a mechanic to use Arcane Defiling in 5e, or is there one out there? The 4E way was not terribly elegant but I don't want to bias anyone. What are your ideas?

In my home setting, Arcane Defiling was originally developed from the Blight Spell, so it borrows some of the mechanics of that spell (even though Arcane Defiling isn't itself a spell)

Basically, in my campaign, Arcane Defiling causes the saving throw of a spell to increase by +2, and immediately destroys vegetation in a radius equal to the expended spell slot level x 10 feet (radius of 10 feet if you cast a cantrip). Creatures of the Plant type have disadvantage on the save, and if the spell deals damage, they take maximum damage on a failed saving throw.

I never played 4e or even 3e Dark Sun, but you could try to use the old 2e mechanics, but set DC based on terrain type instead of caster’s Int score like 2e used.

Preservers didn’t have to check, they got the needed energy for all their spells w/o harmony the environment. Defiling was so powerful because you could actually prepare more spells than normal (or less) and you actually had a faster XP progression. It was basically the dark side, the quick path to power.

If you can make it out attached is the 2e chart.

Tie that to some sliding scale if DC based on terrain and give defilers more or less spells prepared in a day based on their Int check (no proficiencies here!)

The 4E way was not terribly elegant but I don't want to bias anyone. What are your ideas?

I know in 2e the defiler/preserver choice was mostly an "off-screen" thing, but I personally like the idea that a spellcaster can choose to either preserve or defile when they cast a spell rather than when they prepare the spell. And that any caster can be tempted to the dark side if they need the power. And that defiling gives a real trade off. So I'd probably consider allowing any spell cast with a spell slot (no cantrips) to be cast in a defiling manner and then allow the caster to have a number of options - maybe they cast the spell as if it were 1 level higher (for spells that allow that), or the saving throw against it is tougher, or they get a bonus to the attack roll. Or - to go back to the idea that defilers get more spells - that you can make a roll to see if you keep the spell slot instead of expending it (maybe an INT save vs. 11 + level of slot?)

As for the trade off - the blight spell that Bitbrain suggests is a good start. But I think there should be some mechanical problem with defiling as well so that it isn't just a roleplaying enforcement for that trade off for real power. And I like the part of 4e where the defiler gets to make a selfish choice to boost their own power at the expense of the rest of the party - to me that fits with the defiler theme from the setting. Maybe everyone else in your party has disadvantage on all rolls for a round? They're resilient enough that the life energy you suck out of the environment doesn't impact them to the level of costing them hp, but they still are disoriented by it and know what you've done and that rattles them. (Or conversely your enemies all get advantage for a round because they know what you've done and it enrages them?)

Use the 2E rules or find/write your own. This is what I am using.

Defiling
Wizards and other arcane spell casters draw their power from the plant life of Athas. Any arcane spellcaster can chose to defile but Preservers run the risk of becoming a defiler should they do it too much. All player character spellcasters start the game as preservers.

When an arcane caster casts a spell they can chose to defile as a bonus action. Defiling enhances a spells power and the spell is treated as though it is cast in a higher level spell slot. A defiled spell creates a circle of ash 5’ wide per level of the spell. Any living being caught in the circle of ash has disadvantage on all skill checks until the end of their next turn. In addition plant based beings take 1d8 points of damage per level of the spell.

Defiling leaves behind a tell-tale circle of ash and the average Athasian can recognise the ash circle with a DC 10 intelligence (arcana) check as they have likely hears myths and tales about destructive and evil magic. Clerics, Defilers, Druids, Preservers, have advantage on the roll while Defilers, Templars and servants of the Sorcerer Kings automatically make such a check.

Each time a spellcaster defiles they must make a DC 10 intelligence save. Failure indicates that they lack the required knowledge and skill required to be a preserver and the spell caster becomes a defiler. Defilers no longer have the choice to defile or not and every spell they cast defiles creating a circle of ash. A defiler also finds it harder and harder to gather the extra arcane power and may only enhance a spell via defiling once per short rest. Defilers cannot be of good alignment and any good aligned preserver becoming a defiler changes alignment.

Defilers are generally hunted down and put to death by the populace of Athas. Anyone seen defiling is generally treated as a Defiler. Defilers either hide their power, have a powerful patron for protection or dominate a slave tribe or group of bandits. At the DMs option a defiler has disadvantage on any persuasion rolls they make especially a known defiler.

That looks like a good system. Is the defiling radius equal to 5’ per spell slot added or total spell slot?

Does a PC get to choose what slot they want to go up to? Can they do slots higher than they are normally allowed?

Total spell slot level. A 6h level spell slot defiles 30'.

Its quick and dirty, you can use the 2E rules or maybe multiply my rules by X2 and X3 if the land is not fertile (roughly duplicating the 2E idea that varies the defiling by terrain).

I haven't built this out yet, it's just a framework:

If you choose to Defile while casting a spell,
You first cast the Blight spell with a radius of (other spell's level*10 feet) as a free action. Count your kills and add 1 (for the plants in the zone). You get this many power points which you may use to enhance the base spell, using the Sorcerer class feature's mechanics.

A higher-level Defiler can build up a self-reinforcing spiral with his Defiling mechanic, covering a larger and larger area to gain more power to put into the base spell.

A Defiling Sorcerer 20 should be able to defile-cast Meteor Swarm and get an enhanced spell that will cover an entire city and do so much damage that it flattens the buildings and slays everybody inside.

Spells of that power have been done but its NPC type stuff from the Sorcerer Kings usually during the cleansing wars or the aftermath.

To power it you need to defile non plant life which is once again Sorcerer Monarchs and The Dragon.

2E pcs could kind of do some of it level 21 to 30 using Dragon Kings book. You could convert it but its cart before horse atm.

I could see Preservation and Defilement being Arcane Traditions in 5e.
