Legion TD 2

This achievement will either take a long time (or alot of money)

As you will need 10 of the same card (and 4 secret cards to upon up the 4 locked monument slots)
(You equip the monuments under your profile)

To get this "quicker" join up in a Guild, as you will get %more essence by simply playing while being part of a guild,
you can also donate some of the cards you only have 1 of to gain additional %more essence pr. game.

At the time writeing this guide i have 200% more essence pr. game, and i've heard some people are at 600% more essence pr. game,
so join up in a guild as fast as you can

This guide requires 2 players.

Go vs the easiest bots

One person leaks (only goes workers)

The other tries to hold, while also pushing workers (useing pyro)

Send all you got vs wave 5.
