Some edits I don't remember making. Just uploading it to not invalidate my saves. Below is the original description by rottensunlight@gmail.com.

 This addon is supposed to alter the cursed/Darkness tree

to make it useful, while changing as little as possible. I have long
since gone past "as little as possible". I also added the Inner Darkness
tree, an advanced tree meant to supplement Darkness the way that Advanced
Shadowmancy supports the Shadows tree.

-- Creeping Darkness: I lowered the cooldown, I set the number of seeds

            of darkness to increase appropriately with talent
            level. The darkness now inherits a weaker version
            of the debuffs of other debuffing abilities you
            learn once those talents reach level 4. In
            particular, Dark Torrent, and Dark Tendrils. The
            strength of the debuffs are determined by the
            talent level of the talents from which the
            debuffs are stolen, and your mindpower. The
            density of the darkness is based on mindpower and
            talent level, filling up to 75% of the given aoe 
            at 100 mind power and talent level 5.

-- Dark Vision: I increased the max range of the vision to 7

            squares, to enable one to target Agony and
            Hateful Whisper correctly. I also boosted the
            movement speed buff slightly.

-- Dark Torrent: I set the ability to always leave creep behind

            instead of randomizing a core part of the ability.
            I also increased the damage very slightly.

-- Dark Tendrils: I made it faster, with scaling based on talent

            level, and the damage of the darkness it leaves
            behind is improved. I also added an extra
            tendril at talent level 6.

-- Grudge: This gives you a hate/life heal, while

            inflicting the Grudge debuff, which will take
            back the life it healed, plus a little more, 
            making you bleed creeping darkness all the while.

-- Veil Walk: This is just a short range teleport, with the

            ability to switch your place with opponents. It
            gains range with talent level. It is instant if
            you are stepping into your creeping dark. It
            also cuts fear immunity, dark resist and mind
            save when you switch with an enemy.

-- Heartless: This sustained ability burns hate to deal a

            small amount of dark damage on top of every
            blow you deal, and also makes enemies leave
            behind pools of darkness when you kill them.

-- Dark Blood: This ability is pure damage smearing. It collects

            all the damage you take in a single pool and
            portions it out to you over the following turns
            at a set rate.

I have also unlocked the Fears tree, and changed it to be like the version
of Fears in HousePet's afflicted rework. However, the fear effects
themselves have been altered. In particular, the fears that inflict
damage are now allowed to crit, and some of the fears were locked so as to
not inflict brainlock. This has been removed.

I have significantly buffed Gestures to the point of being absolutely brokt,
in the hopes that they'll make a possible alternative to psiblades. I'll
just have to keep buffing them until you don't have to take psiblades, and
then tune them until they aren't crushingly oppressive.

Includes 4 new Class Evolutions:

• Doomed: Hollow - Merge almost completely with your shadows. If you have the original version of Fallen, they can also become Hollow.
• Archer: Zephyr - Lightning-using Arcane Blade at range.
• Temporal Warden: Warp Rider - melee-only specialist.
• (requires Forbidden Cults DLC) Writhing One: Gourmand - This evolution expands the Slow Death tree with a 'Possessor-lite' effect. You can keep the talents you've eaten forever (3 at a time).

Isn't Zephyr already a class?
Yes. https://te4.org/games/addons/tome/qlass-pack But it's plenty different, and lacks a lot of what makes Archer itself.

NOTE: As of ToME version 1.7.3, this fix has been incorporated into the base game, and so should be deactivated/uninstalled.

Tweaks LOS code for both NPCs and the player to properly and consistently respect Dark Vision when determining whether Creeping Darkness blocks sight.

Targeting and projection now properly treat Creeping Darkness as transparent if you have Dark Vision, just like any other tile that can be seen through, eliminating awkward behavior when targeting diagonally and/or around corners. If you do not have Dark Vision, these tiles will be treated as opaque. Additionally, NPCs will properly be able to see and target through their own creeping darkness without hindrance. Similar effects to Creeping Darkness such as Cursed Miasma should also be corrected by this addon.

This addon hard-overwrites engine and module functions. As such, I cannot fully guarantee compatibility or stability.

Now with 200% more botamon!

Ahh, Doomed. For some reason, I've had a lasting love affair with the class. I like hate as a resource, I like spellcasters as my favorite spellcasters, and I like battlefield control and positioning.

But one thing that always kind of irks *twitch* me about them, is their equipment. Well that, and Antimagic.

See, Doomed for the -most- part are will based, and they don't have/use crits on their spells (exception, dark torrent), they don't use spellpower, and they have few spells that you actually use that even USE the magic stat for damage.

I mean, lets list what uses Will, damages, and its effects.

Willful Strike: Low/Moderate damage, large knockback, short cooldown. Low Cost.
Blast: Moderate Damage huge AoE, moderate/large knockback, daze, moderate cooldown. Medium Cost.
Unseen Force: Random strike aura, moderate damage/large knockback, chance to strike twice. Long Cooldown. High Cost.
Reproach: low/moderate damage spread between everything in range 3, with willcheck to damage. Short Cooldown. Low Cost.
Hateful Whisper: Moderate Damage Condition that spread on it's own. Basically, a cool mechanic AoE. Moderate Cooldown. Moderate Cost.
Agony: Condition, high damage total over 5 turns, with willcheck each turn to save. Short cooldown. Low Cost.
Madness: Adds 25% chance with scaling willcheck to reproach, hateful whisper, and agony (per turn on agony) to stun/daze/slow.

So, pretty much a full kit for damage, mainly things with short cooldowns, good damage overall, and good AoE. Good mix of costs. A pretty good kit.

Now, for Magic:

Creeping Dark: low/moderate damage, random style cloud AoE. Mainly used to trigger +~10% damage from Dark Vision, and to block mob LoS. Not reliable for damage. Moderate Cooldown. Moderate Cost.
Dark Vision: utility, if somethings in creeping dark it takes Xtra damge, also, you get scaling 'infravision' (it's not actually infravision) to see monsters with radius. Costless.
Dark Torrent: Beam of darkness spell, moderate/low damage, chance to blind and cause target to "forget" it's target. Moderate Cooldown. Moderate/low cost.
Dark Tendrils: A moving square of creeping dark pins a target in place, moderate/low damge, long cooldown. Moderate Cost.
Arcane Bolt: fire 4 bolts for moderate/low damage total arcane, at closest target. Moderate/low cooldown. Moderate/High Cost.
Vaporize: High(!) Damage, High Cost, Single target for arcane damage. Long Cooldown.

Ok so, here we've got an unreliable AoE damage (mainly used for it's utility), utility, a beam that's a little less than stellar, a spell that's mostly overshadowed by reproach because of cooldown, and it's madness benefits, and a single target decimator that's certain to cost you more hate than it earns. Or rather: Everything under magic has a higher cost, and if you're using it for damage, you probably wish you were using one of your will skills instead. Creeping Dark for damage? Use blast. Dark Tendrils for Damage? Use Agony. Arcane Bolt for damage? Use Reproach. Vaporize for Damage? Put them in a corner and use unseen force. Vaporize is the only one I really see a fair use for.

This is the point: most Doomed don't even really need magic. It's almost all about Will. And when you don't use crit, you don't use spellpower, and you mostly use mostly one stat for all of your damage, your secondary stat is mostly there for your utility skills... Equipment is trivial. Mostly, useless.

If I had to be a naked character I'd be a Doomed anytime, because they mostly just don't care what they're holding, or even if. You'll hold swords and shield just to get resists and retributive damage. Oh looks that one has higher resists and +wil? *tosses penitence for an iron dagger* Oddly enough I'll carry a sling every now and then because it has +%physical damage which benefits one whole tree they have. Doomed have very little equipment out there that actually appeals to them. There's nothing really that a Doomed sees and goes "oh look, that just made my day!"

And while I like that they remove that -need- for equipment element from the game, I almost more thoroughly dislike it. We need a Doomed Staff, Robe, /whatever. I don't want to find platemail with resists and throw it on because who cares about what crazy mage robes have on them. I don't want to hold a staff and know I should be carrying a shield. That's not what a twisted cursed spellcaster does. But it's what a Doomed does, and it feels disingenuous.

Itemization on a doomed is pretty much what has good resists, +will, and that's about it. It needs some more depth.

Personally I advocate changing them so that they use spellpower, with appropiate scaling. I don't think they need the buff per se, and maybe their base damages should be lowered because of it, but it'd encourage more players to actually invest in magic besides pumping Vaporize to "you dead!" levels. (I'm scared to face my clone in ____ because I know if I feed strengths, put them in creeping dark, and vaporize, I hit for ~1140 damage, and I'm capping with a shield at ~890. Resists? Feed strength will just eat them off).

Antimagic Afterthought:

The way things are built presently, since magic only provides utility effects, and you have a complete damage kit with willpower only investments, antimagic -is- viable. Which, is kind of odd for a twisted cursed spellcaster. Now, Antimagic may seem kind of odd, buttt... Deflection + Antimagic shield has some VERY interesting interactions. I'm talking about taking almost NO damage from spells. Your knockback and the statuses from the retributions line/madness definitely help keep you out of the frontline, means that there become 2 thinks only that you really fear: Archers, and Knockback Immune. I leveled and achieved most of my stuff with a Cornac Doomed maybe 4 months ago with antimagic. Corruptors couldn't hurt me anymore. I died to a vault of Greater Wyrms of Power (knockback immune) in the East after having completed most of the game content, I felt like a potential winner. Plus, when you don't care about equipment, it's a lot easier to swallow the antimagic pill.

Personally, I don't know how/which order of operations the deflection/antimagic shield gets processed in, but I suspect it's the wrong one. It feels like 300 damage inc (Ouch!), /2 to deflection split (drain that deflection) shield, 150 damage - antimagic shield, oh look you took sub 100. THAT's without factoring in resistances, of which doomed can pick and choose equipment for resists at leisure, and feed strengths can give crazy resists if you have an opportune target.

Anyways, off to play the game.
