Ice Rod

The Ice Rod is a magic weapon which can also summon static ice blocks. It is bought from the Wizard for 1 Platinum. The ice blocks it summons last about five seconds and appear to cast a dim light, making this not only useful for damage and quick platform making, but also making an incredibly temporary, small light source. Also, when the ice block breaks, its fragments will fall vertically and maintain the light source, making the ice rod highly effective at looking for ores or caverns beneath solid layers of rock the player would not otherwise be able to see through. Summoning an ice block costs 7 mana points.

The rod will fire an ice chunk that will solidify into a 1x1 [non-slippery] block wherever you click. The block lasts for several seconds. If you fire at that location again, the shard will pass through your block and keep going. One combat use of this is to click in a small arc in front of you to create an ice 'shield', then fire through it at enemies.

The ice blocks it creates can be grappled to with a Grappling Hook. This can be used to get to the top of the world and other high areas, such as a Floating Island, more easily; a Dual Hook or Ivy Whip is recommended for this, as you can shoot out more than one hook. You could also simply make "stairs" of ice if you don't have a hook (which you should by this point in the game), but it would take a bit longer.

Regular blocks can be placed adjacent to the created ice blocks, which can prove useful in building floating structures, as one need not build a temporary connection from the ground to the building site.

Before 1.1 release Ice Rod was shown in a dev blog post and the 1.1 trailer.
