This combat spell projects a bolt of negative energy. Some practitioners believe it to be merely energy from the negative material plane... Said wizards are wrong.
The spell actually projects raw anti-matter in a bolt of anti-energy. Materials affected by the bolt tend to disintegrate and be consumed. Spell wards and defences tend to dissolve also. Specific defences exist for the genre of spells similar to this one but they are secrets kept for self-defence.
The bolt only does 1d3 per level of the wizard but it also has the effect of dispelling 1st- and 2nd-level defensive spells. Spells of third through fifth level need to make a saving throw based on that of their wizard to save, and 6th-level spells only fail on a 1. The duration of any such affected spell is usually reduced on a ratio to the level of the spell (DM's decision as to what, though I wouldn't suggest more than half duration).
