Converting OSR monsters to Forbidden lands system

Mon 26 Aug 2019, 19:40

Hi to all, I'm trying to find a viable way to convert monsters (mostly d20 OSR retroclones) to FL, specifically because i'd like to use adventures such as the Trilemma, Dyson, Low fantasy gaming etc and the only problem is unique monsters (undead, orcs, ogres etc are yet in FL bestiary!). I have searched everywhere on the internet but i couldn't find anything...
any suggestions?

The most common answer will be to "eye ball" it and rebuild any osr creatures from scratch, or replace with a Forbidden Lands equivalent creature.

Which is a good approach but I would use the monster generator in the Legends and Adventures booklet to build the osr creature as accurately as possible. The Demon generator in the Bestiary can also be used to fill in some attacks and special features, like stone skin or teleport etc.

I would use hit dice to compare creature strength and maybe armour class for agility (although forbidden lands doesn't use this to avoid being hit), most everything else can be estimated when compared to other forbidden lands creatures.

The most difficult thing will be coming up with the six unique attacks, use the monster generator to get you started and then steal attack descriptions from other creatures in the Bestiary, adjusting Base Dice and Damage up or down as appropriate. And then come up with any other appropriate unique attacks, have a look at my monster generator in my signature for inspiration.

There is no exact science but have fun with it and don't worry too much about balance.

When you're done would love to see your codex, or http://kobold.club/fight site.

Thanks for the suggestions, could we elaborate on an example Monster to have some mathematical guidelines to try ti streamline what Is "streamlineable"? ;-)

This has set my brain onto looking at a conversion system, and so far I have come up with this (but it needs testing) -

Strength = Hit Dice x 3 (+ any modifiers)
Agility = Armour Class - 10 (for ascending) or 10 - Armour Class (for descending) , adjust for armour.
Armour = use list from monster generator in Legends and Adventurers booklet.
Base Dice for attacks = Attack bonus or Hit Dice + 3, where appropriate use agility +3 (remember success on base dice can increase damage of attack). You could also use the listed damage as a base so 1d6 damage, would be 1d6 plus attack bonus/hit dice as base attack.
Attack Damage = Use list in monster/demon generator guidelines.  Attacks usually range from 1 to 2 damage, and occasionally up to 3 for particularly nasty attacks.

Test it out and let me know what you think.

I would still use the tables from the monster generator as a good guideline.

For anything that is close to a creature in Forbidden Lands, just swap out the stats or the creature.  In forbidden Lands you are covered for most standard and creatures, with 3 clans of Orcs included for varying levels of aggression, and plenty of fantastical beasts, for the rest its pretty much make it up as you go.

Thank you Lupex, this Is something i can work on! It would be fantastic if Fria Ligan would release a small official conversion system, there is plenty of too good modules that can be plugged in FL ravenlands, and the MY0 system adapted ti fantasy Is perfect for me!

Let me know how it goes in practice as I haven't fully tested these ideas, but in my head they seem to work.  My main concern would be that Strength scores might be a tad high compared to creatures currently in the bestiary?

Someone on the Facebook group suggested Strength be based on HD+2, maybe try that as an alternate option.

Please post up any conversions you do so we can see how it goes.

Cool.

You may be able to use HP as is for strength as they seem to be a good fit from some of the OSR systems.
