The spell states that Summons in the Gate mastery list is random, however, there are not enough creatures in C&T for this to work, especially at low levels. So instead I was looking (for an NPC) at what possible non-intelligent creatures they could summon, I came across a jadeback, which is a 2nd level giant beetle (and kind of nasty for 2nd level). So obviously if he specifies "6 legged large insect at 2nd level" there is really only one creature that fits into this category in C&T, so in effect he is summoning a specific creature. Is this allowed or does it have to be random? I was thinking that one possible modification to that spell would be that in addition to being able to increase the level, duration doubled, or extra 1st level, there should also be "can specify creature", so a Summons III could summon a specific 2nd level creature. Otherwise it seems all you can summon are things like dogs, horses, cats etc, and nothing more interesting like monsters because these canimals would not normally attack an armoured combatant and probably just run away.
