Slayer Spellbooks seem to only apply to Magery spells (minus Mind Blast) and Mysticism spells, while completely ignoring Necro Spells and SWing spells. Anyone find themselves wishing that Slayer Spellbooks worked with spells such as Mind Blast, Poison Strike, Strangle and a few others that they should, but don't? Mind Blast is the only single target Cold damage spell (other than Harm, which is affected heavily by range, and who wants to Harm spam a Greater Dragon at point blank range?), although it doesn't require Eval for damage. Poison Strike is the only non-DoT based Poison spell that deals instant damage. If Slayer Instruments can affect Despair, then i don't see why Slayer Spellbooks shouldn't affect Strangle. Wildfire, Thunderstorm and Essence of Wind aren't affected by Slayers either, when they should be. Wither shouldn't be affected by Slayers, for obvious reasons (it's already powerful).
