Minecraft

Start up the world with the seed 190800072 on Easy, with the bonus chest and coordinates turned on. Craft a sword, and make your way towards 440, 65, 460. This is the location of the Pillager Outpost. You can either make a bed to set your spawn here or copy a save of this world in case you die. You’ll know which one is the Pillager Captain because they have a large banner over their head. It’s best to attack him when he is alone away from the tower as his guards can be annoying to fight. Once you kill the Captain, you will receive the Bad Omen effect, as well as an achievement.

Now head towards 560, 65, 520. This is the location of a village. Upon entering the village with the Bad Omen effect, a raid will commence, and you should get an achievement for starting a raid.

You have some time to loot the buildings for bread as well as set your spawn with a bed. The raid consists of 3 waves, with 4 enemies each. Try to draw the pillagers close to buildings so you have some cover from their arrows. Once the enemies are killed, you’ll have some time to heal up and put on any armor that was dropped before the next wave starts.

The final wave has a Ravager that spawns, he looks like a rhino. Kill him to get an achievement and finish off the remaining pillagers to complete the raid.

You will then be given the Hero of the Village effect which gives you a discount on trades with the villagers. Do any trade you can and you will get the achievement.

This achievement can be attained after winning a raid. Upon winning you should see the hero of the village symbol on the right (an effect emerald with a ribbon)

You need to speak to one of the remaining villagers, and complete one of their trades that has been reduced

Heres how I did it:
seed: -1813740965

I recommend using a starter chest so that you can craft a boat and make your way to the locations faster. Also, make sure you are not on peaceful, as the pillagers won't spawn

First, go to this blacksmith's chest and if you're lucky you will find iron gear which will help a lot:

1491, 64, -725

Now make your way to the pillager outpost at 1530, 70, -520. Here you need to kill the raid captain, he's the guy with the banner on his back. Once he's dead, and you have the bad omen effect (Read eyes effect on the right) make your way to the village to defend:

1500, 70, -420

Here the raid should start and three waves of 4 lots of enemies should attack (In my experience). Once they are all dead you should receive the hero of the village symbol on the right (an effect emerald with a ribbon)

You now need to speak to one of the remaining villagers, and complete one of their trades that has been reduced

Trigger a pillager raid *Host Only*

This is how to setup for this host only achievement

This guide will also get you:
Kill a Pillager Captain, Kill a Ravenger and Buy Low, Sell High

This guide will also get you all 3 of these achievements. Huge thanks to Idenic for the seed coordinates!

What you need to do for this Achievement is to Sell an Item to a villager at a discounted price. To get Villagers to give you a Discount you must complete a raid first in the village and will be rewarded with the hero of the village buff for a time. During this buff villagers will let you give less of an item for the same emerald. I found this the best with a stone mason. At a discounted price you only need 8 clay to get an Emerald. And after you do so your Achievement should pop. Hope this Helps.
