Okhlos: Omega

This is easier once you have Pandora and Hipparchia unlocked.

The aim here is to get a lot of items to summon phantoms.

Hipparchia will make enemies drop items and Pandora will increase the item drop rate from destroying props as well as giving you extra enemies sometimes when props are destroyed.

Each phantom item summons ten phantoms, so gather up 5 of these items and then unleash them in quick succession.

You can get Pandora from the Angora starting shop and you get Hipparchia after killing 50 cowardly guards.

The subbosses appear around the 3rd area in every city but only under very specific conditions.

You only need to unlock one of these bosses to get this achievement but to get all heroes "Herodotus' Disciple", you need to unlock and defeat them all.

Here is a list of subbosses and their conditions, taken from Hevi's steam Guide.

Delphi Stage: The Oracle - Destroy at least 7 smoke emitters

Ephasos: Calydonian Boar - Find the Mushroom hidden in props in area 1 or area 2, have a slave take it with you.

Sparta: The Hydra - Requires 4 keys hidden in props, you must have 4 slaves bring the keys you find in area 1 or area 2 with you to area 3.

Athens: The Minotaur - Find the special hero called Ariadne standing around somewhere in the first two areas of the city and bring her with you to area 3.

Lemnos: The Manticore - Find the ruby in the previous city (Athens) and have it survive the boss fight to bring it with you into Lemnos.

Atlantis: The Sphinx - Lower spear traps using the mob.. kinda cruel but there you go.

Heroes dont count as people in the mob, so you can gather heroes throughout the game and beat one of the last bosses with your mob almost dead.

I got it unintentionally at Lemnos when the boss killed most of my mob but two of them, but I had almost all of my 22 heroes alive.

I beat most of the subbosses to get more heroes and had a Uni.on Rep with me focused on warriors.

I got lucky and got warrior heroes at least once per area, sometimes two.

So each area I would get two or three heroes.

So yeah. gather tons of heroes for one of the last areas of the games and this one is easy.

Buildings can only be destroyed when your Mob's meter (up top) goes from Cool to Mega Chaotic Mob!!!

Morale plays an important part on this, the more morale stat you have the quicker the bar fills up and the slower it drains out when not destroying stuff.

There is a starter hero called Daedalus you can unlock that makes it easier to destroy buildings and props, making good time to prevent the mob from going down of the Mega Chaotic phase.

The heroine Pandora makes enemies spawn from destroyed props, killing enemies also raises your morale, so its a good idea to bring her along too.

As to finding 75 buildings in a single world, its where it gets tricky.

Each stage has from 8 to 16 buildings, its pretty random.

With 5 areas in each stage, well, 6 if you count the boss area, you will need a little bit of luck to both find enough props and enemies to get MAX morale and destroy the buildings scattered through each area.

The highest Ive gone is 67 but I dont think its impossible, I will make it sometime.

Anyway, hope these tips work for you and cheers!

Update: I finally got it in Athens, the minotaur lair has a lot of walls that count as buildings and it was super easy this way.
