Sorry about that. The conclusion I came up with is that in vanilla BG2 (and probably Enhanced Edition too) only Spell Shield protects against Breach, and only once. Safe from using a Protection from Magic scroll, there's no going around it. Though Spell Shield can be bugued to protect against any number of Breaches but that's pretty much cheating.

Enemies immune to level 5 spells are also immune to Breach, mostly liches.

Using the SCS mod, Breach works in a completely different way. On top of what I said above, it can now work on enemies immune to level 5 spells (liches). (And so can dispel and remove magic work on enemies immune to level 3 spells, still mostly liches)

The spell is therefore much less dangerous in SCS but more enemies use it so spell protection becomes actually useful.

This is a good table regarding how spells behave in vanilla and SCS, which includes the Breach information. Only mistake is that Spell Deflection and Spell Turning (and possibly Spell Trap) should say Ignore in cells shared with the Spell Thrust column, because they don't prevent lower level protections from being taken down. But that's off topic.
