And JYAP NWN2 was released witha screwed up manual btw alot is wrong like the first nwn manual >.> anyway the in game spellbook says IGMS deals 2d6 per missile and 1 missile/lvl to a maximum of 10 missiles so BOOYA and also disintegrate deals 2d6 magic damage/lvl to a maximum of 40d6 but its a fort save or just 5d6 damage and its the same level of spell as IGMS
