summon monster templates ?

[jonhl1986]

so ive been seeing things for adding giant template celestial/fiendish and skeletal templates to monsters summoned with summon monster, is there a way with a feat or item to gain advanced template to the same creatures

Atavism and Mass Atavism, for starters. I believe there's even a Staff that has Atavism as one of its spells.

You could also go with any of the various Shaman archetypes for Druid, found in Ultimate Magic (such as Dragon Shaman and Saurian Shaman).

ok that spell looks nice but ill need a wand of it though i already have rod of giant summoning with a 30k gp spending cap so i don't think ill be able to afford a wand or staff and i think id need umd to use it too since im a familiar adept wizard.
