Best arcane spells for Shadow Reservoir?

[SOLDIER-1st]

What would be the best arcane spells for use with Shadow Reservoir?

[The Raven Black]

I would go for spells that target Will so that you're not hitting the best of 2 defenses.

[Darksol the Painbringer]

Fear, Command, Hideous Laughter, Illusory Creature...the list goes on. And a lot of Will Save spells are pretty easy to flavor with Shadowcaster.

[Perpdepog]

Take Hideous Laughter so you can be a Laughing Shadow Shadowcaster magus whose shadow makes people laugh.

[The Raven Black]

Shadowy Charm FTW.

Really dark and handsome.
