The spell protections get kind of confusing with all the inaccuracies in the manual. The following table sums it all up:
| Capacity | Maximum Level | |
| Minor Spell Deflection | 4 | 7 |
| Minor Spell Turning | 4 | 7 |
| Spell Deflection | 10 | 9 |
| Spell Turning | 12 | 9 |
| Spell Trap | 30 | 9 |
| Shield of the Archons | 1 per 2 levels | 9 |
None of the above protect against spell protection removal, Breach, Lower Resistance, or any area spell.
