Since this author has not been active since August and quite a lot has happened, I decided to update and patch the tomes myself. You can find those here:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3173660790

I don't know how difficult this would be but could you update this so that the unit enchantments effects are in line with the base game enchantments for single hit attacks? The wolf update that came along side the PF DLC made it so that single hit attack get increased effects from unit enchantments. The damage modifiers are doubled and the stat effects are increased by 30%. So sacred oil would become +4 fire and 60% burn chance on things like shock units and Blazing Ordination would be +4 and 90% burn on supports.

This seems to work, might wanna still update though.

I think the Pilgrim's ability to inflcit 2x sundered def/res should be 1x. Burning isnt exactly hard to land, especially if you get the Pyromancy tome.

@Scow2
Outside of perhaps some number tweaking to reflect balance change if needed, I didn't have issue using this tome in my last game.

Updtate for E&A plz.

Not a big deal, but when an enemy resists the Blind effect of Blazing Ordination, it's showing up as "Glühende Verzweiflung - Resisted" rather than the English.

Using the same ruler, but start a new save works fine. Even tried it on multiplayer and with DLC, weird.

It should have no special requirement.
At first I thought, this might be a problem with a recent game update, but after starting the game up, Oath of Purity still works for me with the Human Paladins. Maybe it is an issue with the new DLC race or another mod or something? Nothing I could confirm currently, sorry.

What's the requirement of casting:

Oath of Purity - Minor Transformation
Those able to resist temptation will not fall to corruption; resist cold, blight and status effects.

It won't let me cast it. It says No Valid Target. It should work since it's not a major race transformation.

Huh, currently I cannot even confirm, if the mod still properly works with the new update, but since I haven't heard much I would assume, it works in general?

Besides that, I am afraid I have no special insight in the inner workings of the Steam Workshop that might help here, does it even save older versions of mods? I always thought they would be deleted upon re-upload of newer versions.

Edit: Okay, it does save them, it seems. Still, sadly I have no idea why it would default to an older version, sorry. I have never seen such a problem before.

help, I'm trying to play this mod with a friend but it keeps downloading a different outdated version for them, how fix?

Possible bug: minor transformations don't show up on the race info, though abilities still active on units and everything. Honestly a neat idea for reducing clutter if you use a lot of race transformations..

What about a tome which is like "Tome of The Solar Herald" a tome which idk is a high tier tome that involves useing the sun?, like i think a "Solar construct" which could be idk a sort of statue construct walking on 2 legs and be sorta rocky like the Shrine of smiteing. as this Solar Solar construct would rain down several powerfull abilities involveing spirit and fire. but also idk a transformation spell that is a major transformation that while not the angelic transformation into a celestial turns them into pheonix like people?, as they get great firey wings and a burning aura

@Nathan Pascal

Fair enough since we already have a Chaos Fire Magic tome and Tome of the Horde gets thing done really nice which both are already base game tomes

Plans, yes. Time, eh... we will see.
Two Tomes, Tier I and III again, to fit together with the Tier II Tome of Revelry. Blood Magic, Music, Indulgence, something like that, unless there is already something like that made by someone else? Then it would feel a little redundant, maybe.

You got plans for new Chaos themed Tomes?

Who wants to live forever? I certainly don't, but regardless I give to you; the Tome of Rebirth.
Hopefully not so much is broken this time around.

Icons working perfectly now, tome icon is much better, couid be scaled down just a smidge to match the vanilla tomes. Cheers duder, cool mod!

I remember I did read about that problem of missing spell ability buffs in the forums and made sure to try and include it for my enchantment, although I had to take it away from the Ashen Pilgrim ironically. It just felt weird to remove burn with their abilities, just to apply it immediately again.

Oh, yes, the Pants Update is now out, by the way. Might mention that, too.

I LOVE that blazing ordination affects battlemage AOE attacks. There are so few way to boost those attacks that are supposed to be so awesome but often fall off because nearly nothing boosts them

So, the icons are adjusted again, hopefully they are good now, I don't really have an eye for this visual design tasks, thanks warriorandtoaster for pointing it out.

Pants are good now as well, I only now noticed, even humans were clipping, but I falsely saw it as worn clothing... well, all better now, and the feet of Tigran/Ratkin are adjusted, too, that one I even catched myself this time.

Update will be out in a few hours, probably.

Oh, and the transparencies on the icons are off, you can see the black background behind them.

You probably have this in mind already but I suppose you should adjust the tome icon somewhat, it looks vertically stretched compared to other tomes.

The way you worded that Nathan is hysterically funny. Thank you for the laugh.

Armored Shield unit is indeed planned for the Tier III or IV Tome that will supplement the Tome of Radiance thematically, not sure how long that one will take me, though. First I have to teach those Orcs to wear their pants correctly, it seems.

This mod is great! Keep up the great work and thank you for what you do. Can you Add an armored shield unit?!!!

The Ashen Pilgrim needs a few model fixes. Orc ones with high physique clip for example.

Ooh this is lovely, great mod ! We needed some of that Dark Souls into AOW4 ;)

@Nathan Pascal Fair enough when it comes to the magic attacks part. Could always lower the upkeep down a tier to scale back the bonuses if need be for Blazing Ordination. As for the province improvement part, there is always the option of being very simple and sticking to it mostly being the same as the Ritual Pyre; as I said, simply changing a value for it to be something like stability and mana or something like that and theme it around being a stake to burn the impure or whatever else comes to mind, I think that would line up nicely with the theme of the tome and would also allow nice theming with stuff like the Tome of the Inquisition. Either way, thanks for the response, and good luck with both this mod and any future ones you make.

So, thanks to some advanced techno-magic (Windows Snipping Tool, my hero) we now have individual icons for the mod. Well, they still are the original ones, mostly, but with a unified color theme.

@Blood
I am not sure it would fit very well, Radiance is all about light and purity and conviction, nothing about this one sounds remotely like Chaos to me, other than having fire damage. But for affinity, I feel the philosophy is much more important than the tools one uses to achieve them.

But given your name I cannot avoid to mention now, I was thinking about doing some Bloodmancy-themed Chaos Tomes one day, something to supplement the Tier II Tome of Revelry with a Tier I and Tier III version. I may get a bit ahead of myself, first i have one more Fire-Order Tome to make, when I continue on this project.

Could make this a mixed tome, Chaos/order.

Thank you all for your comments and the interest in my mod. Now, for some answers:

@Tree-vore
Funny thing is, I am usually much more of a nature-chaos-dark type of player myself, and still I decided to start with this one, because I noticed that lack myself.

@BahamuT
I will put the custom art on my list as well, not sure if I actually have access to the game files in a way that allows me to directly use the game icons to make something new? The way they are packaged, I have only seen them via the modding tools so far. Maybe I will try make something entirely new eventually, although I think it has a certain charme to re-contextualize the existing icons, but I see why that might be a little jarring as well.

@Videogamer40000
The province improvement honestly was the part I was least interested in to make, not a fan of that mechanic in general, so I felt I would not come up with anything remotely interesting. I will put it on my list though, if I continue to work on this mod. Not sure about nerfing the Blazing Ordination, magic attacks seem to get the short end with the base tomes already compared to arrows, and the enchantment is already priced one-tier higher in upkeep, so I think it might fit. Thank you for the feedback in any case, I will consider it.

@Raistlain
Per default, all enchantments should stack, mine being no exception. Would you consider double-dipping a problem? I am not quite sure at the moment, but I am not aware of any broken synergies this would produce, and thematically it might fit well, if ones goal is "fire" in general, not specifically 'holy fire'.

I agree with Tree-vore is good to see some new tomes for Order, and this theme is really cool "Holy Fire" type of tome. The only thing is missing to be top quality is some custom art for the spells.

If you want a quick solution to easily make the art more unique, download a free photo editor like GIMP and make copies changing the HUE (with more blue-ish colors or something like that) , to distinguish them from the original ones.

theres so many nature ,shadow and chaos mods out there , im happy order is getting some love

This looks great. Does Sacred Oil stack with fire weapon enchantments? If it does, it may lead to players/AI double dipping and taking both.

Perhaps we could get a different special province improvement besides the Ritual Pyre? Maybe something similar, but it grants stability instead of mana or something like that? Just so, this tome has nothing that's directly the same as the Tome of Pyromancy. Besides that, maybe Blazing Ordination could be nerfed a bit to be closer to Fiery Arrows? Maybe just a 30% chance to cause blind? Instead of a 60% for burning and a 30% for blind if the target is already burning. Regardless, thanks for the mod.
