So, we probably all know that the summoner base class has summon monster I as a spell-like ability, although it lasts for a minute per level as opposed to a round.
Question: Can this be used as summon minor monster? I do like the idea of having a bunch of glowing angelic bats flying around.
Summon Minor Monster is a completely different spell; you'd have to get your GM to house-rule it.
I'm no DM but I would assume that no, summon minor monster doesn't work with it. The reason for me thinking this way, is because although summon minor monster says it's like summon monster, it is still not the same spell nor listed in the summoner's abilities.
