* Positive Energy and healing effects are halved (this includes effects that heal negative levels and ability damage/drain). Conversely, negative energy effects are doubled (all effects of the Necromancy school are included in this effect).
*Teleportation effects do not work across the wards that are built into the city. All teleportation effects do work, however, within/between a set of wards.
*No one has asked yet, but the 3rd ward that you passed through suppresses any non-extraordinary effect that would prevent or limit negative energy or necromancy effects (such as deathward, the deathless armor enchantment, and so on). Artifacts are the only things that have a chance of bypassing this effect, and the Artifact must generate the effect on it's own.
