I think that you need to answer some of the basic questions.
Sight, sound, smell, touch, taste. Design, purpose, adaptation.
Let me ask you a series of questions to consider.
Sight- What does it look like. Not just the fruit, but the entire tree.
Sound- Espescially for an electrical tree, are there any unique sounds that it makes.
Smell- While smell is usually related to flowers, anything can have a unique smell. Does this one?
Touch- What kind of bark does the tree have, smooth or rough. Does the fruit have little hairs on them like a peach, or maybe the fruit has a hard outer layer like a mango.
Taste- What does the fruit taste like. Sweet, sour, bitter, salty...what? If it is like a battery, then it would be highly acidic, and therefore sour, but the electrical charge might be held differently.
Design- What makes the tree work. When and where does the electrical charge build up in the tree or fruit? Does it need an unusual soil to do so? What about climate, and conditions?
Purpose- The purpose of every species is survival, and the breeding of the species. A single fruit requires huge amount of recources for a tree to produce all the sugar in them. Those fruits are usually grown so that animals will eat the fruits and carry off the seeds to other locations to spread. Why would an electrical charge help the tree produce other offspring? At the very least, why wouldn't an electrical charge hurt.
Adaptation- Bark is an adaptation to the surrounding conditions. Bugs and animals that are harmful to a tree must be stopped. Every tree has defenses against it's environment. Certainly an electrical charge might be that, but then, larger critters would never eat it.
All in all, I want to see this submission thought out. If you can't explain why a tree like this might form, then I don't think it has been thought out enough.
I like it. Electical fruits that can be used as shocking weapons against anyone wearing chainmail armour. It gives the phrase "shock troops" a whole new meaning. If a city has an orchard where these frits are grown and an army attacks it, the army could get more then it bargined for. 4/5. Go to Comment
great twists on it guys, thanks for furthering this story, but, let us remember basic physics, it will only discharge through a ground and conductor, (paring knife, your body) and if the party can remove the pit with some insulating item, it could be used to say, create all sorts of fun things, it's a great natural way to add modern elements to any game, oh, and I must say, I do oh so love the thief-zappy factor :) -with more to come and more to not, I bid you good evening Go to Comment
A culture has a tradition of wearing animal pelts as a sign of status or job. Carpenters might wear beaver skins, Masons have a moleskin hood to their cloak, Gaurdsmen might have badger pelts. Done to show the culture's respect for nature and how much of nature is equal to each other.
