Season 2 of adds new content to Zombies, including a new Wonder Weapon you can get and upgrade called the Ice Staff. This tool can freeze enemies with icy projectiles and revive allies to keep them in the fight against hordes of undead.
For anyone trying to complete the storyline of the new Tomb map, you'll need this weapon to progress. Like other Wonder Weapons in , the Ice Staff only appears on a single map.
In Season 2, this is The Tomb, the newest Zombies map that features dark crypts and bobby-trapped halls of buried skeletons underneath an excavation site.
As you may expect, there are several steps you need to complete around The Tomb to obtain the Ice Staff through enemy waves.
You have to pursue vague, smaller tasks to get the Ice Staff, so there aren't any clear instructions provided by the game. Before you can even start searching, you need to be in at least Round 8 of Zombies at The Tomb for the first step to appear.
