AFK Pets and more/Slayer of Evil

"Maybe it's time for cleaning this world from one more bandit!" -Slayer of Evil

The Slayer of Evil is a Pre-Hardmode Boss fought after  King Slime has been defeated. He is the first boss of the mod, though, due to his wide arsenal and multiple phases, he is a formidable foe to new players.

Summoning
After King Slime has been defeated, he has a 10% chance of spawning every high noon. To indicate that he will spawn, the in-game chat will have a message that reads "The sun shines bright with judgement". He can also be summoned by using a Severed Dryad Head, which have 50% chance to obtained by killing the Dryad if Slayer of Evil hasn't been defeated and if he's been defeated it can be obtained by buying it from the Yandere NPC.

Behavior
He can travel through blocks in all of his phases. First Phase When he is summoned, he will first try to shoot down the player with a slightly inaccurate electric charge and change its central location to try to dodge the player's attacks periodically. After some time he will choose one of the following attacks. After fully executing one of them, he will return to shoot down the player, and will then pick another attack. The attacks he can pick are the followings:
 * He will go to the player's left or right. After reaching the player's side, he will shoot one slow electric wave at the player, inflicting the player with the Charged and the debuff if it hits, which lasts for three seconds. If the player takes any contact damage while having the charged debuff it will cause the flow of free charges which causes the player to get the Electrified debuff for three seconds. After a small delay, he will find a new position by the player's side and repeat seven times.


 * He goes to one of the player's sides, holding a . He will then flash a circle around him, indicating his attack. After the circle dissipates, he will dash towards the player. This dash is executed once.


 * He will go high up and to one of the player's sides. After a small delay, he will fire three electric waves, one going in a straight line, and the other two rapidly move in a wave pattern. He will then proceed to go down, and he'll shoot the same three electric waves.


 * Similarly to the previous attack, he will move to a high spot by the player's side. After that, he'll send seven waves in a crescent shape towards the player, and he'll move towards the opposite side. This is repeated four times.


 * He'll move upwards, based on his previous position. After reaching a certain height, he will begin to travel towards the left or the right, throwing down eight colored bottles as he does so. Each bottle deals a different debuff for seven seconds.
 * Yellow: Inflicts the player with the Ichor debuff.
 * Red: Inflicts the player with the On Fire! debuff.
 * Blue: Inflicts the player with the Frostburn debuff.
 * Green: Inflicts the player with the Poisoned debuff.


 * He will go above the player, throwing a grenade at them, which will explode in four electric waves that travel in the cardinal directions. He will then alternate between shooting eight electric waves in an expanding square shape to four electric waves that travel in the cardinal directions, repeating this four times. While he is firing these waves, he throws 2-3 grenades downwards, which will explode like normal.

When he reaches 50% of his maximum health, he will transition into his second phase. Second Phase The Slayer of Evil will perform his "Secret Art", spinning himself at high speeds to form a tornado. He chases the player while shooting three puffs of dust in a trifurcated formation and sending a lightning cloud to somewhere near and above the player. The lightning cloud's position will be telegraphed by a small exclamation mark that flashes orange and red. After some time he will choose one random attack and then return to chase. The attacks that can be chosen randomly are the followings:


 * He will chase the player, while various balls of dust appear somewhere near him and proceed to gravitate towards the Slayer of Evil.


 * Stops in place, and starts spewing out fifteen puffs of dust in a circle. This is repeated nine times, and each circle has a slight rotation difference.


 * He travels somewhere random nearby the player, and after reaching the desired spot, he'll randomly throw five of the colored bottles. This is repeated four times.


 * Stops in place to summon multiple lightning clouds somewhere above the player. The clouds are summoned in a straight line above the player, and they switch between two types of placement;
 * The first bunch is randomly spaced out between all clouds.
 * The second bunch is equally spaced out.
 * The third bunch is also equally spaced out, though the spaces are wider than the second bunch.

Quotes

 * "Why did you kill that Dryad? They are so kind to every creature around them" (When Slayer of Evil is summoned)
 * "Maybe it's time for cleaning this world from one more bandit" (When Slayer of Evil is summoned)
 * "I cannot lose to a bandit like you. They believe in me" (When he falls past 50% health)
 * "-Secret Art- Wind of Justice" (When he falls past 50% health)

Aftermath
When he is defeated, he will start violently shaking and exploding, and the in-game chat will have a message that reads:
 * "It seems chemicals leaked from his jetpack burn him alive"

And if the player has killed the Slayer of Evil for the first time in their world, he will spawn the Yandere NPC (Which is initially tied). After that, the player can save the Yandere, turning her into a town NPC.

Tips

 * Since the attacks of his first phase lock him into a movement pattern, he is very predictable as a result.
 * The bottles he throws can be stopped by blocks.
 * Most of the attacks of his second phase can be stopped by blocks.
 * He can also travel underground and execute his attacks there, immediately destroying his projectiles.
 * Due to his high mobility on his second phase, players might want to consider using high mobility accessories, such as Lightning Boots or  Shiny Red Balloon (or better).
