6) lowered bonus rank for most maps

Is there a way where i can just implement the Tera and Peta healing spells? Thats all i want out of this

How exactly was this made? The disgaea 1 tool set does let me extract the start.lzs. LHAPlus would, but it's entirely japanese and I couldn't figure out how to just unpack the files within instead of converting it entirely.

As someone who just found out this existed I really want to know what tools were used to make this. Making changes to maps seems really fun and I kinda want to have a go at it myself.

I haven't gotten too far into this yet but it's pretty fun. The hospital makes it slightly more restrictive than challenging in some ways and since base spells are low cost where bigger skills are not made mage spamming stronger than the main game imo just not as early on. I do think it was interesting how much swords fell off with sp becoming an actual resource as well.

Ya did anyone figure out how this was made. I made a discussion trying to figure this out. I really want to mod this game and add new stuff and do some balancing fixes and art fixes. https://steamhost.cn/steamcommunity_com/app/405900/discussions/4/371918937281416805/ This is the mod list for disgaea 1 and the disgaea toolpack, and the unofficial disgaea tools kind of work but I don't know how to open some of the file types. If someone can figure this out and make it work so I can mod everything I want ill give you money or get you a game or key. Thank you in advance.

I wrote the tools myself.
Those are now available at HERE [bitbucket.org] for public use.
Also v3 of the mod should hopefully be available at Mod DB soon (if it passes the validations)

What a chad thanks dude, do you want something for this.

I wanted to ask if there is a readme file or patch notes for the 3.0 version of the mod.
I like how Warriors are made for pure melee / counters with minimal SP

Sadly there is no such thing. The mod was made mostly for my personal use to be able to enjoy the game the way i want. Thus no documentation.
The only important changes thatare worth mentioning is that party size depends on your progress in IW. You get one additional member for the first pass of lvl 10, 30 and 100. And one more slot for very bad story ending.
Max enemy lvl is 100,000. Player lvl remains the same.
Those two aspects may require additional planning and should be known ahead of time
Eveything else can be discovered by playing.

Thanks for the answer.
On a side note, I don't know if it's fixable, but Scavengers (Valkyries) with guns that are summoned from the Dark sun have the 5-10 hit but still do a lot of damage (probably based on ATK).

I'm really enjoying this mod, the difficulty is something refreshing, it's making me to think outside the box, making me to be more creative in the game.

I'm making a series of livestreams of this mod (I think I'm the first to do it on Youtube), I really enjoyed.

Good work xmontex!

The mod is literally unplayable in the late game
Late bosses hp overflow integer limit and they have negative hp, so it's like ghost units that count dead and you can't interact with them https://imgur.com/a/HK50i0K
Also when i try to start prinny baal battle in LoC game just crashing, i guess it's because prinny baal hp overflow too much
Also after first cycle story Laharl fight is impossible because Rozalin stats is much lower than Laharl stats
Also with some bosses dark sun effect that spawn units just crashes game(Etna, Laharl, Baal for example)
Also i didn't get extra party member for worst ending
Even still, I really enjoyed the mod
For those wondering how I got this far:
1. Survive early game and complete Colosseum Depths
2. Create male samurais and get those hp to critical(to abuse their special(you still need to do at least 1 damage to make deathblow chance to proc)) and unlock dark world
3. Unlock Colosseum Depths - Confession Room dark world(requirement has changed and now it's just complete without taking damage)
4. Abuse Confession Room with your male samurais(throw the marionette closer to your base panel to turn her back and then attack with your critical hp male samurais to deathblow). I recommend get at least 5 2000 lvl samurais, also i recommend to have at least 1 of them caster to complete story
5. Get some high rank gear for your units(there are nerfed bonus level everywhere but mystery rooms, so you need to go to your highest level gear item world and find mystery room and then get maximum bonus gauge in the mystery room fight to get good gear(best fight is cellphone store because you can always throw prinny when you get 9 bonus gauge)(also stronger enemies bill increases bonus level but i don't remember if it works for mystery rooms)) and level it(you need to have fist user that unlocked rising dragon and another high movement speed unit to scroll item world)
6. With those characters you need to complete story and then complete Axel mode to unlock magichange
7. Get magichange scroll from subpoena(you need at least rare, but legendary is a lot better) and level it to at least level 140
8. Abuse magichange glitch with midboss to get god weapons(you can google it if you don't know how to do that, do not forget to get lovers for your monster because it gives crazy boost to weapon stats)
9. Complete the game
