Player Abilities

Instead of emotes you could have up to four abilities. Abilities are certain powers or actions a player can use if unlocked, some are taught by Villagers, some are found in enchanted books, and others can be unlocked by interactions with Piglans. The abilities vary in power and usefulness, like Duel Wield (You can put a sword instead of a shield in your offhand, dealing more damage!), to Smoke Bomb (creates a cloud of smoke and turns you invisible for 3 sec, as if you died.), even Analyze Monster (a small window above you mob you are currently looking at displays the name, health, and buffs or debuffs currently affecting the mob you are concentrating on.) The more you use an ability the stronger it becomes! At the highest level, Analyze Monster can also see the inventory of another player! (Yes it works on players too and the abilities are not cross world, you would have to find/unlock them again on a new world.) It would give the game a more magical feel, as if there is so much more waiting to be discovered.
