I actually think much of the Tome of Corruption's mutation tables were copied from the original Realms of Chaos, just with the mechanics updated and some of the sillier entries removed (but not all of them).

Now, the whole thing of making perception a characteristic (rather than a skill) actually could be seen as a step backwards. The truth is that very few skills key off it normally (Awareness and Psyniscience as far as I can remember), so it could be argued to be characteristic bloat.

I would like to see a unified ruleset based on DH (1st edition....) and WFRP 2nd, but there are areas which present problems, namely the interactions between modern and primitive weapons and armour.

Tome of Corruption is everything Black Crusade should have been, gorgeous splatbook.

Agreed. After reading Tome of Corruption I was rather disappointed in Black Crusade's narrow selection of mutations and gifts.

Seems like the farther back you go, the more gifts and mutations the sourcebooks have: "Realm of chaos: Slaves to darkness", for WHFRPG (1dt edition) has perhaps the most: A D1000 (yes THOUSAND) chart of mutations!

This seems like it's steering toward the Golden Corral "Quantity over Quality!" line of thinking. How often is your average group going to need 1000 different mutations? Couldn't the time and space for that be used for something better?

You say this but you've never had a player thought "Oh Fantasy, sweet I'll play a noble Squire who is brave and honourable" despite being told it's not that sort of game, and then leave three sessions later because one of his legs got jealous of the other leg and ate it up, leaving him a one-legged crippled freak. He was warned! In the same campaign the Dwarfs head melted after being knocked down a pit that had a fair few chunks of warpstone in it. It wasn't all bad though, a little person grew out of the puddle that was his neck and spoke for the Dwarf! it even had little arms and adorable bucked teeth! Chaos is great fun, you just need to open your eyes and heart to it.

No, I haven't had a player that ended up unhappily leaving my game.

I have to really say using the "Big Book of Chaos Mutations" (as our group calls it) from WHFRP is amazing for games, also makes Navigator mutations more fun. We prefer to do multiple rolls, as not all fit (or some are too extreme) and then sometimes tweak it (In one game we had a Navigator who became a catgirl sorta) depending on how serious the tone is and such.

Honestly, an updated version of that would be a great addition to all the lines, but ESPECIALLY BC.

I know what you mean with "to extreme".

The "Chaos Were" mutation in wich makes you transform from your (well) normal form into another creature... with it's own set of further mutations! ... and of course that ends up with cross breed, zoological mutation and Chaos Lord with another D6 chaos atributes... Ugh to much of a good thing that one!

Now, the whole thing of making perception a characteristic (rather than a skill) actually could be seen as a step backwards. The truth is that very few skills key off it normally (Awareness and Psyniscience as far as I can remember), so it could be argued to be characteristic bloat.

Having it rolled into Int, on the other hand, leads to all sorts of ridiculous situations with all ranger-type characters being geniuses and all scholars and mages being able to determine a mosquito's sex from a hundred paces, because spending their lives hunched over dusty tomes somehow makes their eyesight **** impeccable.

Running it over WP, as in the ability to properly "focus" works better, yes.
