Clear Majority achievement strategy
The strategy is simple.
You need 3 friends. (I know it will be hard to gather them)
At the table choose not a public game, but for friends (then you can invite 3 people, not just 1)
To get the achievement, you need to collect more colorless crystals than other colors.
(2 Colourless 1 red 1 blue 1 yellow X, 3 Colourless 2 red 1 blue 1 yellow ….)
Who is getting the achievement will choose numbers from 7-1
All the others from 1-7
When the round comes to choose 4, if there is no colourless one, you choose 4 so that the round burns out.
If there is a colourless one, then someone from 3 must choose 7.
There are a few caveats.
You need to win. Few times the game didn’t give an achievement if someone else wins. So it is for the best that the other 3 do not choose the same colour.
If in some round there will be 2 colourless Achievement will not trigger. I think it is not fulfilling “collect every Colourless Gemstone”
