caster school specialization

[GlassDeviant]

I had forgotten about the school specs, and let my Enchanter go over 50 in Spec Evocation. I've determined that the character id is 6 and that Spec Evocation is skill_id 47 (because it's the only skill at level 74 in the table), so I have put together this SQL statement:

update character_skills set value = 45 where id = 6 and skill_id = 47;

I'm pretty sure the SQL is valid, but I am wondering what adverse effects there might be on this character, like not being able to level a different spec due to some flag or value elsewhere in the db that I am unaware of.

Edit: This is on a solo server btw.
