I received this email earlier today.
Subject: Your Monster Maker
Okay, I have been trying to find stuff for 3.5e of D&D.
Mainly, how to make a monster.
Even more-so, HOW DO YOU DETERMINE a monster’s Challenge Rating?
I can’t figure it out for 3.5. I’ve scoured the net trying to find how to determine a custom-made monster’s challenge rating. Please, if you know, help.
I rendered what little help I could, in this reply:
Compare it to existing monsters, trial and error, etc.
There’s not a formula or anything to determine CR.
Also, most of my expertise is in 4th edition
Didn’t think much of it, a little surprised to get a question about third edition, but nonetheless nonplussed. Then I received his followup.
Well, I’m trying to stat out monsters from Final Fantasy. I’m running a Final Fantasy campaign, and the final boss is Yiazmat. His HD is 490,197 with a constitution modifier of +90.
Well, thanks anyway.
I’m going to pause for a moment and let that sink in for you.
I was absolutely flabbergasted by that. I’ve heard of people running ridiculously-powerful games in third edition before, but the sheer scale of this was utterly mind-boggling. I mean, even without knowing what sort of hit dice this boss has, the constitution modifier alone was worth 45 million hit points!
The longer I sat around, the more questions I had, and finally I decided to ask him for an interview. He graciously accepted.
Asmor: Hey, thanks for granting the interview
Matthew: np. My name is Matthew, but my handle is Nexis Firehawk
How would you prefer I address you?
However you want.
Ok, so Matthew, how long have you been running this Final Fantasy campaign?
Well, it’s been in design for well over 5 years.
I actually have several classes that I wrote based on the original classes, including the Dragon Knight (Dragoon), the Archer (hunter), and the Sorcerer Variants Black Mage and Summoner.
I got the urge to make it something more tangible after the release of Final Fantasy : Dissidia.
So, finding players is hard.
So I take it the game hasn’t actually started yet, then?
No, but I’ve got 3/4 of my prep-work done.
The sheer scale of your boss encounter astounds me, and it makes me wonder how much of D&D 3.5 is still recognizable in the game you’ll be playing
So have you had to modify the system a lot?
A little bit. I took the Spell Points variant from Unearthed Arcana. I love that book.
I also learned how to impliment a Materia System from Final Fantasy VII
Your boss you’re designing, Yiazmat, has 490,197 HD. How did you come up with such a specific number, as opposed to for example 490,000 or 500,000?
Because I know what his HP is. It’s (roughly) 50,000,000 HP, and after you know his Constitution score (190), all I had to do was plug in the rest of the numbers. I maxed out his HD for the sheer fun of it, though ^_^.
He actually has 50,000,94 in my game, but the real Yiazmat has about a million more, but I figured what’s a million after THAT MUCH HP?
Indeed. What level are your characters going to be starting at?
Well, considering the fact that it’s a massive, multi-world campaign, I’m starting them off at 4th level.
There are 11 Main Bosses.
Plus, once those are all defeated, the players will have the fun of fighting the 4 weapons from FF VII, Culex, and a special, custom boss I made.
What level, roughly, do you expect the players to reach by the time they fight Yiazmat, and how long do you think that will take them?
Well, I know that the players should gain roughly 6 levels per world, since I’m somewhat tailoring it to them, so I expect them to hit level 60 or 70 easily.
And I ignore the Epic Rules, because the difficulty of this campaign would be too much if I didn’t.
Characters gain levels normally.
How are you doing advancement past level 20, then?
Just normal progression. Effective Caster Level and the like still go up, but the classes and Prestige Classes cap off at their normal maxes, whether it be 20, 10, or 5.
Things with normal, mathematical calculation on how they are achieved (like a fighter’s Bonus Feats or a Monk’s Unarmed AC) still progress normally for things calculated beyond 20th level.
Like, for instance, a 20th level monk with 10 levels of Psionic Fist (aka, Fist of Zuoken).
Then give him a monk’s belt.
In this campaign world, the characters will need every bit they can get.
I can imagine!
Lol.
The main antagonist (not Yiazmat), is actually a deity.
Characters will get to interact with Cloud, Squall, Bartz, and other Heroes from the Final Fantasy Universe, as well as fighting Sephiroth, Sin, Ultimecia, and even Lavos.
Have you considered how long the battle against Yiazmat might take? Even if the characters averaged 10,000 damage a round against him, that would still take 5,000 rounds to kill him. Do you have any way of mitigating the length of that combat?
Actually, yeah. Lots and lots of Mountain Dew. Lol. But seriously, Yiazmat only reaches his height of power when he’s near death (12,000,000 HP), so the first bit of combat should fly pretty quickly.
But I also plan on having Players rolling all their attack die, declaring each one for their six main attacks.
Yes, there isn’t just 4 main hand attacks. There’s 6.
Then they roll for their off-hand attacks.
Then all damage is added up.
Also, all players will be rolling at the same, so there will be a bit of trust between me and them.
Yiazmat actually has a very low AC
It’s a good thing you’re not playing 4th edition, where AC is based on level!
Yeah.
His AC is 42.
Well, anyways, I think you’ve answered all my questions. All I can really say is, “Holy shit.”
I wish you the best of luck in your campaign when it finally gets off the ground!
