#17275 Defensive Spin should grant the correct Armor Class bonus at level 9

(Easiest to check with NearInfinity, no repro case necessary.)

In BG2:EE, the Blade's Defensive Spin ability (SPCL522.spl) is missing certain steps in its level progression. From the spell's description: "The character [...] gains a +1 bonus to Armor Class per level, up to a maximum of +10."
The Blade first receives this ability at level 1, and the minimum level of a Bard at the beginning of SoA is level 8. However, the spell only grants Armor Class bonuses that correspond to a caster level of 1, 4, 6, 8, or 10. That means the spell is missing the appropriate Armor Class bonus for the Blade at level 9.

Note that in BG:EE the same ability is correctly implemented with the complete level progression from level 1 to level 10. It can be used as reference.

Also note that in BG2:EE, the ability has some weird additional spell levels beyond level 10, which are no different from the level 10 effects. The additional levels can be removed. Again, see the correct BG:EE version of the spell for comparison.
