Warning! This is only my opinion, your maybe different.
This thread is going to be long. There's a lot of weapons on skyblock that have use for players inside of dungeons.
I will rate weapons from F- to S+, based on their value, damage, usability.
Raider Axe.
Super early game weapon. With max counter outdamaging AOTE, however gets fastly outclassed by other weapons.
B tier.
Dreadlord sword.
Very very Early game mage weapon, super easy to get, costs next to nothing, deals pretty solid damage, has no cooldown on ability. However, very fast getting replaced with other weapons.
B+ tier
Dragon Shortbow. Early game shortbow, upgrade from artisanal shortbow. Obtainable from quest of Lone Adventurer. Used on very low dungeon floors by early game players. Costs nothing, you also can't sell it, because it is soulbound. Has same attack speed as juju, however way inferior stats and isn't dungeonizable.
B tier, great for very early game archers.
Bonzo's staff
Upgrade from dreadlord sword. Costs way more than dreadlord sword, but still very cheap. Used on phase 1 of floor 7 to get crystals, decent damage.
A tier.
Aspect of the Dragons.
Used by early to mid-early game players. Has usage for berserkers and mages.
For berserkers - offering high single hit damage.
For mages - ability is nice, has no cooldown, on 1.9+ it is basically question of your CPS, as it won't activate block animation, therefore it doesn't slow you down and your DPS equals to your CPS.
Very Cheap.
S tier
Zombie Swords.
Here, i mean exactly Zombie Sword and its upgrades(Ornate Zombie Sword and Florid Zombie Sword).
Dungeonizable. However more often getting used as healing items in pair with Wand of Healing and it's upgrades.
Very cheap. Nice heal item.
S tier.
AOTE/AOTV
You can't dungeonize them, however it is the best mobility items in the game. Fairly cheap, used to get secrets. I aam sure you can apply Etherwarp on both of them, which is basically high-reach instant teleport.
S+ tier. Everyone should have those items.
Adaptive Blade.
This weapon is meh. It's damaging stats are worse than what AOTD has and costs more than AOTD. It adapts to your class... Cool ig?...
C tier.
Frozen Scythe.
Mid-Early game mage weapon, good for clearing, also uses like no mana. As weapon - upgrade from bonzo's staff.
A+ tier.
Glacial Scythe.
Upgrade of Frozen Scythe. Gets 3 blocks range explosion, when hitting the ground, also increased ability damage. Quite expensive, good for clearing.
A+ tier.
Spirit bow.
Upgrade from Dragon's shortbow. Drops from floor 4 post-boss chest. Has worse attack speed, but increased damaging stats and is dungeon weapon. Used by mid-early game archers.
B+ tier.
Phantom Rod.
Hella underrated. It does fairly low dps, however stunlocking your enemies, therefore you dont need to get close to them. Very cheap. Great for Early to Mid-Early game.
A- tier.
Spirit Sceptre.
"Shoot bats! More bats! Bat Power!" - words of players, who use this weapon. Mage weapon. Same way to obtain as Spirit Bow, except you will need to drop Spirit wings to craft this weapon. The explosion of bats has radius of 6 blocks, which is same as what hyperion has. Way more expensive than Frozen Scythe.
A tier.
Yeti Sword.
Acts like budget hyperion. Thats about it. Lots of Ability Damage, quite expensive, doesn't offers healing or damage reduction, unlike hyperion, also has cooldown. Still quite decent weapon.
B+ tier.
Livid Dagger.
Dagger means fast. Thats about it, has 50% attack speed, so it is dealing nice melee dps. Deals double damage, if backstab. However backstab most of time can't be used. You can also throw your dagger, but uh, it is 5 seconds coodown lol.
Great for mid-early game berserkers. Also cheap. Drop from post boss chests on floor 5 of catacombs.
S- tier.
Shadow Fury. High single hit damage. That's a about it. Used by early-mid game and mid-mid game left click mages. Acts like budget giant's sword. Sometimes even outdamaging giant's sword.
A+ tier, quite expensive, very rare drop from floor 5 post boss chests.
Last Breath.
As weapon has close to no use, however used to reduce defense of Necron and mini-bosses. Cheap, good utility item.
A- tier.
Spirit Sword.
Just remembered about this thing. Too bad it is quite expensive and is barely better than adaptive blade. L.
F- tier. Needs to get buffed.
Necromancer Sword.
Decent damaging stats. Used to spawn summons, used on Voidglooms mostly by RCM mages. Not so expensive as shadow fury.
A+ tier.
Flower of Truth(FOT).
Quite decent clearing weapon, you can swap FOT to high single hit damage weapons, so it will deal more damage. Relatively cheap and Floor 6 requirement is very easy to get. In terms of clearing outclassed by some archer weapons.
A+ tier, because it is super cheap.
Soul Whip.
Acts like alternative weapon to FOT and AOTS. You can spam right and left click weapon, therefore nice clearing capabilities. Also you can swap it to high single hit damage weapons and the damage of those weapons will be applied to Soul Whip's hit.
A tier.
Bonemerang.
Relic of the past. Used to be the best archery weapon. However bonemerang swap is now not just patched, but also became insanely bugged, so the 2nd+ bonemerang will do fraction of damage. So you can only use one bonemerang and... It is meh weapon. Decent for protectors ig...? But overall inside of dungeons offers very low damage per second, as it takes ages for it to get back. Used by mostly very lazy early game players, who can't buy juju... But they forgetting about existing of spirit bow so...
C- tier.
Juju Shortbow.
Massive damage per arrow, very high attack speed, usually used by high-ego archers, who don't remember about existing of talismans, for them talismans are god's forbid. However decent as weapon, usually gets overrated. If you use this weapon get atleast 300 MP, however highly recommended to get 400 MP. Insanely cheap for its damage capabilities.
Dungeonizable. 2nd best archery weapon.
S tier.
Midas Staff.
Does highest single hit right click damage in compare to any other RCM mage weapon. However blocks archer weapons, therefore drastically decreasing your social credit, making you "average midas non". Quite decent for clearing. Btw, since it blocks arrows of your teammates, it also blocks any other mob's projectile, therefore, acts like a shield. Also quite expensive for 100 million midas, but it is worth it.
B tier.
Giant's sword. Used mostly by LCM mages, before upgrading to Dark Claymore... And by monkeys in necron's armor... With -1 talisman amount... . Very high single hit damage. Used by berserkers in pairs with AOTS.
A tier.
Axe of the shredded. Itself AOTS doesn't do a lot of damage to mobs other than Zombies. However, turns out you can use the ability of AOTS and swap to giant's sword, shadow fury, dark claymore and the melee damage of those weapons getting multiplied by up to 1,6x. However doesn't really has use on MM, except for tanks, because this weapon heals you on hit. Quite expensive. Also used to reduce the defense of enemies.
B+ tier.
Terminator.
Best archer weapon. However hard requirement and price highly dependent on Diana Mayor. Used by Late-Mid+ game players on archer and berserker class.
Outside of dungeons: Used on Hitphase of voidgloom and primary weapon of high tier kuudra.
Insane Damage, however very expensive.
S+ tier.
Wither Blades.
Healing. Good clearing capabilities. OP outside of dungeons. Requirement of floor 7 comp doesn't seem to be hard, but after you got f7 comp and looking for a price of those blades... You really wanna to irl trade because those costs 1,7B coins.
On MM primary use - healing stick with teleport abilities. Might used as clearing on even MM, if you avoiding mini-bosses.
Good for Floor 7 and below.
2nd best mobility item.
S- tier. Cant give it S or higher, due to unfairly high price and in future it seems to be even higher.
Dark Claymore.
Strongest single hit weapon in the game, insane for late-game+ LCMs. Expensive, very rare drop from Master Mode Floor 7. Requires Master Mode Floor 7 completion, which is very hard to get.
Outside - really nice weapon.
S tier. Usually... No use beside LCM in dungeons. However claymore itself not so expensive.
I think that's all weapons that being used by players. If i missed something - let me know. Feel free to tell your thoughts on this weapons if you disagree with placing.
