Wall of Suppression wrote:
The wall blocks line of effect, so no spell or effect can pass through the wall, but it does not block line of sight. Magic items or spell effects with a higher caster level than yours are unaffected by the wall of suppression. The wall does not affect artifacts, anything stemming from the direct action of a deity, or similarly powerful sorts of magic.
It blocks line of effect. True seeing would not extend through the wall of suppression.
Although, true seeing affects the creature, and transforms his vision. It is not a cone or other shaped effect like detect magic or arcane sight. It merely modifies your vision.
So...true sight works just fine unless the character walks through the wall of suppression.
