Getting past forbiddance

[gnrrrg]

We've come across an aea where several zones of forbiddance have been cast and we can't afford to lose the HP discovering where the borders are by blind chance.

Is there any way to mask your alignment so that you won't be affected?

Unseen alignment specifically says that it only protects you from divination (forbiddance is abjuration).

what level is you crew and what spell lists do you have access too?

Not directly what you're asking for, but what about anti-magic shell?

Since Forbiddance allows spell resistance, any effect that works against such spells should work against Forbiddance. The spell Spell Resistance, for example.

The Forbiddance spell allows the caster to provide for a password to bypass the effect. Grabbing some of the caster's minions (especially those who seem to be of a different alignment) and interrogating them for such a password might be one option.

Oh, the spell, Imbue with Aura (Ultimate Magic), may be the closest thing you would be looking for. But it requires a divine caster of the same aura alignment as the forbiddance you're trying to get past.

Corruption Resistance (APG) can reduce the damage sustained, but not by much.

13th level cleric is our highest caster. We have a wizard and a summoner of 10th or 11th level. We have a multiclass that does not exceed 5th level in any casting levels.

We believe the forbiddance is being cast by someone of 14th level or higher.

Antimagic field is phrased just vague enough for the GM to deny it by fiat.

We've got one character with a high enough will save and an alignment such that corruption resistance might ge them through unharmed.
