nice book ! but im looking for rolemaster second edition book

This is the best combat system I've ever read. The book doesn't really go into detail of mechanics too much, as you will need "Rolemaster Fantasy Role Playing" and "Gamemaster Law" for those details, but this book has a full set of tables for how 29 weapons perform against 20 armor types. Slashing weapons (sometimes) end up as blunt criticals against heavier armor, piercing does better against chain, and there is even a martial arts section for how sweeps/strikes performs against different armor types, as well as "monster" tables for natural weapons like beaks, claws etc.

Even if you don't play Rolemaster, you should get this book/PDF for the fun of reading it over.

This without doubt the best edition of Arms Law ever. If using Rolemaster it is simply the best option around. Optionally the product is also usable with other gaming system, but buyers be aware that the needed tables for handling magical combat is found in the Spell Law modules of Rolemaster.
