The slimes which cannot drop the Slime Staff are: Lava, Dungeon, Umbrella, Hoppin' Jack, Corrupt (Shadow), King Slime, Queen Slime, Crimslime, Gastropod (Spectral), Rainbow.
King Slime is able to spawn additional ordinary Blue Slimes. It will always drop one piece of the Ninja Costume when defeated.
The staff is an extremely rare item (0.01%) drop from all slime monsters and slimed zombies. It is a useful item almost throughout the game, especially pre-hardmode since the baby slime can slow almost any monster with its minor knockback.
An easy way to get this staff is to use Slime Statues, with a thin layer of lava. Another way to get the item is to use Slime Blocks that will increase the slimes' spawn rate. Use it alongside with a Battle Potion and Water Candle for a better slime spawn rate.
Jester's Arrows are the preferred ammo type, due to the high single target damage of the former and the piercing effect of the latter. Snowball Cannon is another strong ranged weapon. All guns are very effective against King Slime, although they require breaking a Shadow Orb or Crimson Heart.
Fighting King Slime is completely optional and not required for game progression, but his defeat may reward the player with money and useful items. While King Slime is alive, the music Boss 1 will play.
The Royal Delight is a pet-summoning item which is dropped by King Slime in Master Mode with a 1/4 (25%) chance. It summons a pet Slime Prince which follows the player around. The pet resembles a miniature King Slime with blush and small dotted eyes.
The Slime Staff has the lowest drop chance of any item in the game and is, therefore, the rarest.
Abigail's Flower can be uncommonly found as a plant growing on grass near a placed Tombstone, regardless of world progression. Its spawn chance is increased in a Constant world.
Each of the Tavernkeep's sentry summon weapons come in three tiers: Rod, Cane, and Staff; with the Staff being the most expensive and the most powerful.
The Golden Slime has a 1/180 (0.56%) chance of spawning in place of any standard slime as opposed to the regular 1/400 (0.25%) chance for a golden critter to spawn in place of the standard one.
The Gold Slime is the quickest and most daring slime of them all. This slime, with a rumored 1/10,000 (0.01%) chance of spawning anywhere, has the most valuable plorts in Slime Rancher.
According to Redigit, the main developer behind Terraria, the ninja is the Guide's brother. Nobody knows how the Guide's brother ended up trapped inside King Slime, and the guide never mentions his brother's existence.
He is really powerful, cheap to upgrade, and possesses one of the most powerful wave clears in the game: Special Power: The King Slam. "Slams the ground with all his weight to stun enemies for 2s" dealing damage equal to a normal attack, but attacking and stunning every enemy on the battleground.
King Slime is an excellent enemy to spawn, as each slime spawned can drop the Amarok. By Hardmode, the player should have little trouble handling the boss, as well as an abundant supply of Gold/Platinum for crafting the Slime Crown.
The Slime Staff generally has the rarest drop chance of any weapon, with minor exceptions. The typical drop rate from most slimes and Slimed Zombies is 1/10000 (0.01%) / 1/7000 (0.0143%) .
Moon Lord is the hardest boss undoubtedly within Terraria. This boss is considered as a Hardmode boss that occurs post Lunatic Cultist.
Coin Gun is the most powerful weapon, if platinum coins are used as ammo, which can deal 200 damage and has an insanely fast rate of fire.
Remember, slimes only spawn if you are farther than 24 blocks away. Unfortunately, they will also despawn if you are more than 32 blocks away. With this farm, it's best to create a small area within this range to AFK in. To maximize your use of time, try AFK fishing while waiting for slimes to spawn.
Mosaic Slime's Plorts are, along with Tangle Slimes, the most profitable (outside the elusive Gold Slime's Plorts). They can be quite easily ranched, once they've been found.
Also the statue drops the staff, and I am 200% sure about this since I dropped 3 of them in 10,000 kills in 1.4.
