I came up with an idea, but other players can supplement it or fix it, i not be interested in spider health and speed, i just came up with what kind of behavior and abilities he has.
It can also be not a spider, but another creature Scorpion is best suited, but its difference from the spider is that the spider jumps and bites the player, but scorpion stands on the ground and stings using tail.
Sand Spiders: They have a sandy texture and they spawns only in the Desert, they are dangerous in day and night. But the most unique thing about them is then what they creep out from the sand and pounce on the player. They also impose an effect of when bite (I did not invent what effect, definitely negative).
