The goal here is to get full crystal armor and almost max out the resilience (you have to hit 400)
What you need
Ruby crown or amethyst helmet
Crystal chestplate
Crystal boots
Tough mania (or just Chain shirt)
Clay gauntlet
Clockwork Heart
Frozen soul (or frozen heart)
Enchant every item with tough, on top of the screen there is a orange slime it has to say "4 additional summon from Ruby set. Now you're just a showoff".
Done, all other achievements are pretty self explanatory. !
