Molotov Cocktail: Fire damage
Poison Gas: Damage health
Smoke Bomb: Blindness... essentially makes you invisible to affected enemies - even though you're not really invisible.
Sleeping Gas: Massive fatigue damage
Bomb: Fire damage plus force
Napalm: Massive fire damage
Deadly Gas: Massive health damage... instant kill for petty/lesser/common foes.
Some ideas I like, others not so much and I'll tell you why.
Throwing bottles of poison whether(acidic/corrosive/poisonous)--yes good idea
Throwing bottles of poison that you could shoot in mid-air with an arrow(for added challenge and kudos) to shatter the glass and spray a charging enemy with its contents--yes awesome idea.
Flammable or conductive substances that you could ignite with a fireball or charge with a lightning bolt--yes cool idea
A gas that damages fatigue or health--yes good idea but only if the cloud was unpredictable and could envelop you and do damage as well
But anything that can self-ignite or explode on contact I don't like, because if such a thing were possilble then what comes next--Explosively charged rifles? Handguns? The Elder Scrolls VI: Modern Warfare--No I don't think they should venture off in that direction.
I'd love to see more ingredients, recipe books for potions, measurements and weights, etc. used.
Imagine;
You need 30g of Flax for a recipe. You have a pair of scales, with 3 x 10g weights on one side. You need to add x amount of chopped flax to balance the scales.
After that, you need to dilute it with 250ml of water. Using the anologue stick/mouse, you tilt a beaker of water into a measuring jug until it reaches 250ml.
Now add 30g of ground Steel Blue Entoloma Cap to the mixture.
Now also imagine that making errors in the recipe resulted in a penalty to the final bonuses granted to the potion. E.g., you instead have 33g of Flax, 300ml of Water and 27g of Steel Blue Caps, that means you have an error margin of 10% on Flax, 20% on Water, and 10% on Steel Blue Caps. This means a total error margin of 13% for the potion, meaning the final bonuses will be decreased by 13%.
Now also add into that mixture that some weights and measures might be estimates, or plain wrong, and it is up to you, the budding alchemist, to find the right ratios.
I like the idea of making the actual science of alchemy in the game a little more complicated and esoteric for those that spend a lot of time making potions.
Personally I would like it if none of the ingredients had their actual effects listed, until you tasted them. Then perhaps the effects could automaticlly appear in a virtual alchemical journal in the player notes or inventory and as you attain new levels in alchemy more effects would reveal themselves to you when you re-taste an old ingredient you've already tested.
This process could be made deeper when you begin to combine multiple ingredients to create potions or poisons. Rather than have to match ingredients together that have common effects, perhaps all combinations could create something(some terribly powerful and some that are no more than duds), but which combinations will create the most ideal potions/poisons would remain a mystery to the player until that combination was tested in game through trial and error---Think of it as an all new form of exploration for the budding alchemist.
Lastly, the act of creating a potion could translate into a mini-game in which you have to work the pestle around concentrically with the mouse or gamepad--perhaps pushing a button at the right time for extra pressure until the ingredients are ground down and ready to be diluted etc. Each ingredient could be given its own distinct, ideal consistency that you would strive to achieve when in the mini-game to maximize the potency of the potion. Achieving this ideal consistency would be the point of the mini-game, but could also be bypassed for those that can't be bothered with it.
What if any house you bought had a garden you could use to harvest alchemy ingredients? It would be kind of like the one at Frostcrag Spire, but it would start off empty. You could then buy or find seeds to plant it with!
Yes. Excellent idea!
