This is really rather poor. The author is verbose and overly impressed by his writing while not actually managing to say anything interesting. The rules themselves have been overriden by later Mongoose products and the the alternate effects for runic integration are mediocre.

Can't really see any reason to buy this product.

Blech! This is NOT what I had hoped for. This is the first time I've been seriously disappointed with a Mongoose product.

It adds special powers for integrating runes. It gives randomization tables for each of the core-book's runes, given from 3 to 6 different powers. You can only get one per rune.

It allows you to try to integrate a second identical rune for a second runic power... but you'll need a Persistence score over 100... which means you need a POW of 21+ to have a chance... due to the Player's Guide limit on Persistence of Pow x5.

It does not add any runic spells.

It's overpriced for the utility. Knock $2 off, and it would be worth it.
