As i said, it would have been useful to include some optional rules for the summoned creatures.
Nothing TO specific, but some general abilities, level dependant attacks, DB and OB modifiers for every planar summoning spell etc.
That would have helped to get things started and to get some guidelines how not to break the balance completely.
Type I equals Level 1 and 2 isn't very helpful, beause there aren't any summonable creatures besides animals of this level.
To tell you the truth, one thing i don't really like about rolemaster is how often the players and the GM are left in the rain.
Take combat from the second frontline with a spear for example.
There is one paragraph about this in the character law, but nothing that is even remotely helpful.
I can appreciate the desire not to restrict freedom of choice, but at least give some optional rulings, one can use but don't have to.
By including nothing helpful, in essence you tell the buyers of the product :"Make someting up!".
That's just lazy, and to be honest, thats not the reason i buy "rulebooks"
But thats just me.
Anyways, thanks for your insights.
