Rabbits are the simplest and easiest animal you can hunt, since they provide no real harm to the player. It runs away from the player upon sight. It is faster than the player, so it is recommended to corner it into an object to kill it. Spears are also good for counteracting their speed.
The most common of the aggressive mobs, it runs towards the player upon sight and will not stop until line of sight is broken or the player is far away. Slower than the player and easy to outrun. Deals damage when on top of the player. It is recommended to run away and hit it every so often. If you have decent gear the wolf is an easy kill. Upon its death, the player will receive two pieces of raw meat and Wolf fur. The wolf does a lot of damage, around 1/5 of the players health bar.threads, which is used to make bandages, earmuffs and coat. The spider doesn't do as much damage as the wolf, but is much faster, and with its trappings ability, almost inescapable.
*As of the newest update, Spiders are weaker than wolfs. They immobilize, but, do less damage.
Quite similar to the wolf it is easily killed by using a spear.
The Polar Bear is the stronger of the two animals currently in the snow biome making it very difficult to fight without post-snow gear or plenty of friends.
Since the bear is so difficult to fight, it's recommended to avoid them altogether, and go for foxes instead.
If you really want to kill one it is recommended to attack with a spear because of range.
One easy way to farm for polar bears is to take advantage of their slow speed, and kite them while running in circles around a fire. It is recommended to use a sword while doing this, for extra damage. If you use this technique, make sure not to keep hitting the fire as after about 15-20 hits the fire will de-spawn, leaving you vulnerable to the cold.
*The dragon deals 1/3 damage, recommended to kill it using spear.
*The dragon can be avoided by explorers hat making it much easier to collect the Amethyst.
When being chased by a hostile mob, remember that they chase you in short bursts of movement. So if you run around a small object, like a wall/tree, you will most likely lose their aggro.
Keep in mind you can run faster than a wolf, but slower than a spider. A wolf is easy to kite, and slowly kill as long as you have some kind of weapon. If you only have a wooden or stone pickaxe, avoid hostile mobs, as the reach provided from the pickaxe is very small. If you are inexperienced, or want to play safe, wait until you get a sword or spear before engaging a wolf or spider. While it is possible to kill a wolf by punching it to death, it is not recommended as your fists do not do a lot of damage and it may take up the better part of the day.
Before going to the snow, arm yourself with a backpack, a Wolf Chapka, and multiple fires to fight the cold. A furnace and a hammer (to pick up the furnace) would also be a viable choice. A golden spear will probably do you better than a golden sword due to the range, but it's up to you. You can shimmy down the map, stopping periodically to kill foxes and place fires, before you can obtain some diamonds.
