Path of Exile

This can be done across multiple characters, does not need to be done on a single one. Can be tricky to wear them all on one character due to the stat requirements for each weapon, but not impossible... just get a few amulets, belts, etc that boost your stat.

For the purposes of this guide, I'm only going to worry about the basic version of the weapon. Higher tier versions will obviously need higher stats to equip.

If you wish to be able to equip them all, you're going to need:

118 Strength
118 Intelligence
124 Dexterity

There are 13 weapons in total, the full list can be found here:
https://pathofexile.gamepedia.com/Maraketh_weapon

The basic 13 to look for are:

Etched Hatchet
Dagger Axe
Reflex Bow
Double Claw
Prong Dagger
Wyrm Mace
Horned Sceptre
Morning Star
Crescent Staff
Hook Sword
Smallsword
Curved Blade
Pagan Wand

Maraketh weapons start to drop during Act 4, with a level requirement between 34-36. Pretty much anywhere in Act 4 and above will drop the weapons, but Act 4 has a higher chance for them to appear as its closer to the enemy level of the stages. I have not seen these weapons appear at the vendor, however they do appear on the Trade Board if you're really stuck for one or two items, just the ones found here are generally good quality rares or high socket items, and expensive.

Probably the biggest tip I can give, when you've killed a bunch of enemies, hold in Left Stick - this reveals ALL item drops that the filter hides from you. As you don't really care how poor the item is, white, low level, low socket items will do just fine.

As you equip each weapon, keep an eye out in the bottom-right corner. There will be an in-game text-based description showing you've gained progress towards completing this challenge.

Achievement unlocks as you equip the final weapon.

I created an item-filter using filterblade.xyz that highlights all weapons that you can use: https://www.filterblade.xyz/?profile=bitje&saveState=B3J... (it's based on Neversink's Strict filter, so you might not want to run this permanently). You can link your PoE account with filterblade and automatically sync the filter to your game.

If you run a map with this filter active, the weapons that you can use show up with a dark-green background, light-green text, green beam and a minimap star icon so they really stand out :)
