Grenadier
The Grenadier has focused their studies on the creation and mastery of explosive arms.
Features
Explosive Innovator
Beginning at level 3, you've completed the plans to create your grenadier bombs. During a long rest, you are able to prepare and keep a number of bombs equal to your Intelligence modifier. Only you may use these bombs. A bomb costs 1 silver in materials to create.
As an action you throw a bomb within 30ft. of you. All creatures in a 5ft. sphere make a Dexterity saving throw against your Tech save DC. The creatures takes 1d8 fire damage on a failed save and half as much on a success. This damage increases by another d8 at the 6th, 11th and 17th levels.
Additionally, you may craft one specialty bomb during a long rest. These bombs act as though you cast that spell centered on the point where you threw your bomb. The effect of your specialty bombs is challenged using your Tech save DC. You may only possess one type of each specialty bomb at a time. The bomb effect lasts the maximum amount of time the spell allows for concentration spells.
You may build a specialty bomb to cast its spell at a higher level by temporarily giving up a bomb slot for each level you want to raise the casting level of the specialty bomb. The slots return after the bomb is used.
Specialty Bombs
Planned Detonation
Beginning at the 3rd level, you know how to adjust your bombs to prevent friendly fire. As a bonus action you may select a number of creatures equal to your intelligence modifier who are unaffected by the effects of a bomb you use during the same turn.
Proximity Detonation
Beginning at the 6th level, you can set your bomb to go off when any creature wanders within 5ft. of the bomb.
Plentiful And Potent
Beginning at the 11th level, you double the number of bombs you can create during a long rest and can carry. Additionally you may hold two of each specialty bomb. Additionally your basic bombs can be detonated with a range up to 15ft. radius.
Bomb Launcher
Beginning at the 17th level, you've developed a specialized launcher for your bombs which mounts on your forearm. You double the range of your bombs. Additionally, damaging effects of your bombs deal additional damage equal to your Intelligence modifier.
