Hi folks, I am working on a few things for a campaign I am putting together, and one of things I am adding as this upgrade for an Alchemical Dragon: (the wording is still wonky, I only just came up with it)
Alchemical Rocket Boosters:
These powerful engines can be mounted on the side of the vehicle instead of siege weapons. They can be used to provide bursts of speed when necessary. Activating them requires a DC X Craft: Alchemy check (Haven't decided on DC yet). They can be used up to 12 times a day. When active they increase your acceleration by 10ft and your maximum speed by 20ft. This speed increase lasts for 5mins, and can be kept up by expending additional uses. Alternatively, you can overcharge them for a greater burst, increasing acceleration by 30ft and maximum speed by 100ft instead, but this bonus only lasts for 5 rounds, and then the engines can't be used again for at least 1hr so they have time to cool down.
So how does that seem as far as numbers go? And what should they cost?
The idea is to give up armaments in exchange for not needing to get caught in a firefight. In this campaign there will be a fairly large number of flying vehicles etc.
I don't know about the price, but the "usable x times per day" seems weird to me. Just make them use up some kind of fuel that needs to be refilled after x uses.
Well I might change the main bonus to a constant passive one, but I want the overcharge option to be limited... I like the fuel idea though. Maybe I will just price them the same as the siege weapons they are replacing would be...
