Wooow, never got a notification that you had replied. So sorry. ;-;Nicely done.
( Kanchiki Suna no Jutsu ) - Sensor Sand Technique
Type: Supplementary
Rank: C
Range: Short - Mid
Chakra cost: 15
Damage points: N/A
Description: The user will release a special type of sensory sand across a terrain and then upon contact with an enemy target the sand can alert the user of the location and presence of an enemy target. The sand can even detect invisible targets and stick to their body.
Quite a useful sand technique, surround yourself with a swirling mass of sand that spreads out over the battlefield. It will give you information on movement and enemy locations, good to use if you lack sensing or if the opponent is trying to hide from you.
I focus my chakra and release a unique variation of minute sand particles that have the ability to sense and cling to targets that have masked their presence. The sand aggregates everywhere up to a mid ranged radius.
Advantages:
Great way as you said to combat against enemies that have masked their presence. No hand seals required so it can be done fairly quickly.
Disadvantages:
It'd be nice if it reached up to long range given that it's supplementary. It's also inferior to chakra sensory since it can't distinguish incoming techniques, only the enemy's presence.
