Demolitions Expert

You lear to turn oil and other materials into actual explosives, explosives will function as variation on the Shatter spell depending on the description of the volume of material being crafted. The bomb will have base DC for creation of 11. Damage gets divided by each possible target in the area.

(rate of conversion: 2 basic unit of material for each dice of damage, each 4 basic unit for each 3ft² of area of effect )

You get proficiency with brewer's supplies, so you can alter the explosions in the following parameters:

- Directionality: i.e. instead of exploding in a sphere, explode in a cone

- Time: you can calculate the fuse time correctly

- AoE: you can change, adding or subtrating, the size of the area of effect (but no point chages), +1  DC for each 5ft²

-damage type: Thunder (Shockwave, those dont use oil) or Fire

Each parameter changed will alter the bomb creation DC in 1

You can cast Identify as a ritual targeting a building, or geological formation, to locate weak spots, explosives located there deal double damage.

Example: i have 20 flasks of oil and want to emulate a fireball -> 10d6 of fire damage, 15ft² radius explosion -> DC 11 -> Boom!

20 flasks of oil, explode in a cone, lager radius explosion, say 30ft²  -> DC 11+1+3=15, missing target DC will cause reduction of effect, if a 14 total gets roled, the bomb has smaller area, if 11 total its the standard fireball.
