Archers could be chased down with a little trouble(if I didn't want to use a spell, such as Call Lightning). Iron gates are subject to Rusting Grasp. It wouldn't wreck the whole gate, but a three-foot radius hole is big enough to walk through. Thick stone walls could pose a problem(assuming I'm trying to get through it). Summon Nature's Ally 3(SNA4, if I'm crunched for time) can get me a Thoqqua, though. Thoqqua have a burrow speed and specifically leave a usable tunnel behind. It's small(so you have it/them make more than one, and combine them) and it's also "blisteringly hot", so use create water to cool it.
At worst, I'm left with the same options as a non-caster.
*For reference, the spells I'm talking about are all PHB, and the Thoqqua is from the Monster Manual. We didn't really use a lot of books other than the core 3.
So you are casting spells as a tiger usng a feat?
