i will tell you how to get 1 of them, i dont wanna spoil too much. so you make a new account and don’t get a sense stone, you should be able to save more than 2100 gems at the second to last level in the forest. then go to https://codecombat.com/play/level/the-mighty-sand-yak?, for that level use the code
hero.say("message")
hero.say("message")
hero.say("message")
hero.say("message")
hero.moveXY(26, 30)
hero.say("message")
hero.say("message")
hero.say("message")
hero.say("message")
hero.moveXY(36, 30)
hero.say("message")
hero.say("message")
hero.say("message")
hero.say("message")
hero.moveXY(46, 30)
hero.say("message")
hero.say("message")
hero.say("message")
hero.say("message")
hero.moveXY(56, 30)
hero.say("message")
hero.say("message")
hero.say("message")
hero.say("message")
hero.moveXY(66, 30)
hero.say("message")
hero.say("message")
hero.say("message")
hero.say("message")
hero.moveXY(76, 30)
because you dont have the sense stone.
keep resubmit it until you pass, then at the next level it will say that you are required to use the AMBER SENSE STONE, it costs 2100 gems, so you should be able to buy it. That’s how you get the amber sense stone
