He wants to know where you paste that. The reaction file, probably.
Okay, can you give me a code for the most damage-resistant skin/flesh, the sharpest claw material, and the least breakable bone possible? Because that's the only way I'll be able to survive more than a few weeks in adventure mode. Seriously, I've been through over a dozen adventurers in one world without the year changing while playing dragons and GCSes.
So...You want to play an invincible adventurer? You do realize that that would be no fun, right?
Well here is a good base, I use it in my "Angel" mod. It is basically adamantine with a heavy boost. It makes the creature immune to almost all physical attacks (except those of the same kind) and still makes you pretty strong. If you make your creature out of that, or just the skin/claws/and bones, you should be able to take most vanilla creatures.

To make is stronger, put a few 0s after the "Heavy". Making it more unbreakable can be difficult, but if you can lose with this your mod might be a bit overpowered.
