Sammy, Sonic Fan

Sammy, Sonic Fan is a Frickmode boss with an outstanding 400,000 health and 750,000 in expert mode.Sammy is intended to be fought right after the Moon Lord. Even with post moonlord gear, the boss can be quite challenging.

Sammy has an AI similar to that of Retinazer, however this may change in the future.

When Sammy is alive, Boss 2 will play.

Spawn
Sammy, Sonic Fan is summoned at night with a Suspicious Looking Backpack. The Suspicious Looking Backpack is crafted with 20 Silk, 30 Souls of Fright, 20 Souls of Mario and 10 Luminite Bars.

Sammy will scream "ALRIGHT! THAT IS IT! THIS IS THE FINAL STRAAW!" when he is summoned. If the player attempts to summon him in the day, he will not scream.

Only one Sammy can be summoned at a time, and Sammy will despawn at daytime.

Weapons
The Moon Lord's drops and Pillar weapons are recommended for this fight.

Ranger Weapons: Melee Weapons: Summoner Weapons: Magic Weapons: Armour is pretty self explanatory, just choose the one your class' armour set.
 * S.D.M.G - Chlorophyte bullets would be optimal, since Sammy's head is only the size of Skeletron's.
 * Phantasm - Strongest Bow available. Holy Arrows are the strongest choice.
 * The Korean Dream - a Post-Moonlord rocket launcher - Rocket III is the strongest rocket
 * Meowmere - cat projectiles bounce and pierce, which is useful since you can hit Sammy multiple times with one swing
 * Star Wrath - stars are very powerful and since they don't come out of the sword, you can do it under protection of blocks.
 * Stardust Dragon Staff - No explanation needed here, extremely powerful summon.
 * Rainbow Crystal Staff - one of the most powerful sentries in the game. If the summoner stays in one area, it can deal a lot of damage.
 * Lunar Portal Staff - same reasoning as the Crystal Staff.
 * Last Prism - its beam of light deals insane amounts of damage.
 * Lunar Flare - Similar to star wrath but for mages.

Accessories
A set of wings or the UFO mount is recommended for mobility.

Endgame class loadouts would be optimal for this fight, however, all accessories should be reforged to Warding, especially if the player is a mage or summoner which are glass cannon classes.

Arena
If the player wishes to avoid its lazers, they may want a long stretch of Asphalt blocks.

Campfires, heart lanterns and star in a bottles are recommended for mana and health regen.

Buffs
Ironskin, Regen, Endurance, rage, wrath, Lifeforce and class specific potions like Sake, Mana Regen, Summoner ,Archer and Ammo Consumption potions are recommended.

Well Fed is also very important.
