My idea for Chemist as a healer
I have been wanting a non-magic healer for a while and I think this could be the perfect fit forvthe first one.
In my idea the chemist will use a rifle. I was also thinking that a crossbow could work. The theme is that they make and use their potions, poisons, gases, and grenades. Their armor options would be a mix of metal and leather and with bandoliers and a utility belt (which I would like to be changeable unlike the Astrologians deck sheath) It would shy away from the robe aesthetic.
We already have a pure big heal type, and preventative shield type, and a hybrid that buffs allies. This one healer would focus mostly on AOE heals and AOE damage. It would have no shields and would focus on debuffing enemies rather than buffing allies. Also this class has less actual abilities on the hotbar than others but actually would have more total abilities since it has a bunch not assigned to the hot bar due to the nature of the class. Uses both TP and MP.
The special mechanic would be the Mix ability, and this would also be the "gauge" that is displayed. The way it would work is you would activate the "Mix" ability and then use the ability of the item you want to mix. You will then see that item on the gauge. You would then do that again to add the second item in the mixture. Once set you can use the ability "Use Concoction" and it would then use what you created. Not all items are mixable.
As always, I'm sure the numbers are probably a bit out of wack but its structured to show the concept as well as I could.
