Class choice:Power Spike Caster Build

[Wubbles]

Hey all
I’ve always been quite fond of the concept whereby a caster character is able to drastically increase their power for a short time before a sort of cool down or consequence. Think barbarian rage for a mage, or a super Saiyan charging up on a caster. Is such a concept possible in the current pf1e system? Which class do you think fits this full caster build best?
Thank you

HI uhhhh yes and no????

So there is this class from psionics (which is 3rd party but like really good stable 3rd party) called the Wilder who does literally exactly this.

Yeah, I played a Wilder once. One of the funnest classes I've ever played.

There is the Acadamae Graduate feat for (non-universalist) wizards to summon monsters with a standard action. It requires a Fortitude save or you are fatigued afterwards. It's 3.5 material, but PFS allows it (if that matters).

A wizard (spell sage) can increase the CL for a single spell by 4. You don't pay with a condition, but you lose arcane bond.

1st party, i think kineticist is closest to what you want.

Nothing goes Super Saiyan quite like a Bloatmage.
