What is really great about this book is that the size of looted equipment is mentioned.
It states, that wondrous items and rings mostly adjust to the wearers size, but arms and armor don't.
And there are spells and other solutions for this.
Also there are feats that enable you to fight with larger arms and very useful teamwork feats like the good ones from Dragon Slayer's Handbook, but unlike the lame ones from Demon Hunter's Handbook) against ALL creatures which are larger than you -
NOT ONLY AGAINST GIANTS!
I really love the artwork from the center spreads lately, they are gorgeous and really show in this case how big the different giants are in relation to a human and each other.
One thing is WRONG in this book:
The damage from small and medium sized weapons is switched and needs to be switched back.
