Lazy ass. Take into consideration salt, as in sea water. Though there is no defined agreement in the RP on how that would work I generally dont use ice in sea terrains, at least some techniques. You can use ice normally in Iwa, as for Suna, they would be formed slower or not all depending on the tech.
Now, analyze the techniques, tell me how they should be performed, and try to to impress with anything that comes to mind.
(Hyouton no Jutsu) Ice Release Technique
Rank: C
Type: Supplementary
Range: Short-Long
Chakra Cost: 15
Damage: 30
Description: The user can use this jutsu to make it begin to snow down on the terrain, or, much like the “Earth Style Technique” the user can make small pillars or shields of pre-existing ice or make it materialize. If this is used to make snow, then after 3 to 4 turns most of the terrain will be covered.
(Kyousei Hyouton no Jutsu) Greater Ice Technique
Rank: A
Type: Offensive/Defensive
Range: Short-Long
Chakra Cost: 30
Damage: 60
Description: Similar to the original, weaker technique, the Greater Ice technique allows the user to, by making a simple hand seal (Ram) produce walls, pillars, etc of snow or ice. The ice constructs are rather simple in nature but resilient and strong, with the user being able to materialize them anywhere short range (though from that point they can grow up to long range) from him from the moisture in the air. He can, however, use any proportional water source within short-long range of him to produce said constructs. These can also be directed and propelled as projectiles towards targets. In both cases, the size and possible uses are limited only by the users will, chakra and skill. It also allows the user to cool down existing moisture in the high atmosphere to bring down a snow storm, similar to the original technique yet stronger and faster acting. This snow storm will not directly harm anyone but is useful to cover the field in snow rather quickly (2 turns) and to hinder visibility, sense of touch and hearing on anyone caught inside. The user is not immune to these effects though and must spend 15 chakra points per turn to sustain the blizzard, while becoming unable to mold other elements than Water, Wind or Ice.
Also, any ice techniques you would like to learn before others? Not like the entire training will take much time, but still.
