Ancient temples in jungles(like the Mayas)

My idea isn't only "adding a new temple(s) to jungles", but also adding features and/or mechanics based on many things from mesoamerican regions(not only the Aztecs/Mexicas and Mayas, also the mysterious Olmecs) from the actual center of Mexico (like the Aztecs) to de region Gran Nicoya in Costa Rica (all the pre-hispanic groups that lived in Mexico, Guatemala, Belize, El Salvador, Honduras, a big part of Nicaragua and a part from Costa Rica[the region known as the Gran Nicoya, known today as the province of Guanacaste], in this case not only adds structures, it adds new weapons (a variant of the new spear made with obsidian, an axe and a sword with the same material, with this material players will cause a new potion effect known as bleeding or a similar name, meaning the obsidian is VERY sharp [actually a obsidian knife is even more sharper than a knife made out of steel], but it won't have a great durability because is like a crystal-rock formed by the fast cooling of the lava, so instead of using obsidian block to make it, players will need to use obsidian fragments, these could be crafted or founded in structures, also a new armor of jaguar skin; but these armor CAN NOT BE CRAFTED, being only obtainable by structures or with jungle villagers(the villager that sells armor) and in some rare cases the swap or savanna villager, also coming with a new type of shield. This could add variations to some structures that generates there, like the trail ruins and jungle temples
