To carry this hammer of ice into the battlefield, you’re going to have to do a fair bit of farming. Its blueprint can be picked up from the Market for 15,000 credits once you’ve reached MR6. Alternatively you can purchase it premade for 165 Plat.
What makes this one a grind? Well, to build you will need to offer the Magistar as tribute, along with 30,000 Cryotic. And no, I did not add an extra zero by mistake, you will have to protect up to 300 Extractors if you’re not using boosters to save up for the Sibear. On the plus side, if you build it, no other in-game item requires as much Cryotic and only one other requires more Alloy Plate, so you’ll knock out one of the larger farms.
