Does ballistic skill affect spells?


I’ve noticed that some spells, e.g. the necromancer’s Doom, say “missed” when they are cast at a target but fail to connect. Would raising the ballistic skill of the caster increase the chance of hitting? I know this works with the arrow spell for the basic magic users.


Only spell that requires BS is the Silver Arrow spell. For Doom it say "missed" when the spell fails, i.e. the target succesfully passes its strength test. There is nothing you can do to increase the success rate of that spell other than selecting a target with a lower strength as it is dependent on the target's strength.
