nº1 Companion II - I usually like to have two companion II at the same time while playing. This says a lot , doesn't it? (Spell Law is the other book i like to have two copies while playing)
nº2 Companion I
2.1- I had a selfmade book with most used weapons, criticals from differente companions ( Acid, Plasma, and normal Slash, krush, Superlarge, this kind of things), some pages from alchemy companion, some optional rules we use. t's a combo of various companions, so i don't know where to put it.
Nº3 Various, Companion 3, Arms Companion, Companion VII ( we use the arms master a lot)
nº4 Companion V and IV.
Nº5 Sometimes someone uses Elemental companion, Spell Users Companion, War Law, Sea Law, but all this companions depends of the game, and we don't use it normally.
nº6 For no reason we have never used Channeling companion. I have Companion VI, but I don't remember if think i had never used it because its very far from our games.
