Sorry this took so long but good job, any questions on those two?
If not, in the time it took me to reply the jutsu list has been updated for fuuin and as such, there have been several new ones here, notably the Barrier techniques have been moved to fuuinjutsu. You likely already learned them during your old ninjutsu training but still, just a refresher course then lol. The first three are all relatively easy and simple, easy to use but likewise easy to counter.
(Kekkai: Tengai Hojin) - Barrier: Dome Method Formation
Rank: B
Type: Supplementary
Range: Short- Mid
Chakra cost: 20 (- 10 per turn to keep active)
Damage points: N/A
Description: After clapping ones hands, this technique creates a spherical detection barrier above ground with the user at the center. At the user's command, the detection barrier can expand, grasping everything in the battle field. The user is able to detect anything that moves inside the barrier space with his or her own "sense".
As you see, it's easy and a nice jutsu to use for a few reasons, those reasons being 1. It's good if you have no type of sensory jutsu or ability and 2. It's good if you have no type of sensory jutsu or ability. Really, that's about it lol. There isn't much usage for this one as there are a few normal jutsus that give this same effect, such as Chakra sensing rain. And it's also easy to counter with one of the below fuuinjutsus. Questions?
(Kekkai Houjin) - Barrier Method Battle Array
Rank: B
Type: Attack
Range: Short
Chakra Cost: 20
Damage Points: 40
Description: Kekkai Houjin is a high-level Fuuinjutsu trap technique. An array of explosive markers is jointly placed around the boundary of an area. If any opponent walks through the boundary, the seals will activate and explode.
This is actually somewhat good. You set up explosive seals around a boundary of an area, such as 4 kunai with explosive tags around them and throwing them around a 5 by 5 meter box in front of the enemy as they run into it. It leads to some creative uses, though it likewise is easy to counter. How would you counter this if used with kunais and if it's used on stationary markers, like boulders or trees?
(Kekkai Kireme no Jutsu) - Barrier Shatter Technique
Rank: B
Type: Supplementary
Range: Short - Mid
Chakra cost: 20
Damage points: N/A
Description: The user will insert their chakra into a active barrier to then interfere with the source and cancel the barrier shattering its shell.
Note: Must make direct contact and only works with up to B rank barriers.
As you see, this one is very simple. If low ranking barriers are used against you, such as the first jutsu posted, this is the easiest and most efficient counter to them.
