Artificer - Grenadier

The Artificer Subclass was inspired by the fine art of Explosions. Grenadiers are good at one thing blowing things up, they have a wide selection of fine explosive devices for dealing with any situation. Mechanically yuo get a number of free grenades a day from the grenades table and can make more using spell slots. Their is also a Playing with Explosions Table for when others try to use these explosives. At later levels your grenades can cause shell shock, have extra sharpnel, and you become better at taking damage from area of effects (presumably from blowing yourself up repeatedly). The final ability is of course a Nuke because what explosives based subclass would be complete without one.
