Type I tags are generally used for training, distractions, and other non-lethal activities. They vary from E-rank in power up to B-rank, depending on the tag.
Homing Tag
Rank: E
Once activated, homing tags attract chakra and allowing jutsu to home in on the tag. Due to the fact that a ninja could use a Type II tag instead if the opportunity presented itself, the tag does not see much combat use and has become primarily a teaching tool.
Alarm Clock Tag
Rank: E
Alarm Clock tags receive an amount of chakra and slowly releases the chakra at a precise rate. Once the inserted chakra empties, a small 'reserve' amount is used to deliver an E-rank Raiton jolt to the attached body. It works effectively because the precision in the emptying rate allows a ninja to know how much chakra to insert into the seal on activation for a specific wake time.
Smoke Tag
Rank: E, D
As the name indicates, the tags release smoke for several seconds (for E-rank, the D-rank version releases more smoke for about a minute). Slight variations in the seal allow for different color smoke if desired.
Paint Tag
Rank: E, D, C, B
Another multi-strength tag, paint tags release an amount of paint a few seconds after activating. The paint tags are frequently used in practice and sparring to stand in for Type II tag use. Seal variations allow different color paint.
Flash Tag
Rank: E, D, C, B
Flash tags emit a blinding flash of light for a few seconds.
Sound Tag
Rank: E, D, C, B
Similar to flash tags, sound tags emit a temporarily deafening noise a few seconds.
Flashbang Tag
Rank: D, C, B
A combination of the flash and sound tags, the flashbang tag delivers a simultaneous blinding flash and deafening noise when activated. These tags are often used when forcing entry when enemies are waiting inside.
As the name suggests, Type II tags are those designed to injure and kill other people. All tags in this category are a minimum of D-rank and can go up to B-rank in power.
Security tag
Rank: D, C
Typically referred to as "burn" tags, security tags are used to destroy documents, other tags, and so forth. They are often used as part of a security system for sensitive material in areas where it's likely someone might attempt to steal them. They also see frequent use when trying to get rid of sensitive documents when about to be captured. When activated it creates a small fireball that will incinerate most items within a small radius around the tag. The tag is available as D-rank (0.5m radius) and C-rank (1m radius) versions.
Omni-directional Explosive Tag
Rank: D, C, B
Abbreviated to "omni" or just "explosive tag," Omni-directional explosive tags are the most widely used combat tags in the ninja world. When detonated in the air, it results in a spherical fireball centered on the tag. Higher rank Omni tags have more powerful and larger explosions than lower ranks.
Directed Explosive Tag
Rank: D, C, B
The other form of the 'generic' explosive tag, the directed tags are designed to aim most of the explosion to the side of the tag the seal is on. This results in a bit more of a focused conical explosion shape than omni tags, but generally require more planning in their use. Like Omni tags, higher ranked directed tags have more powerful and larger explosions than lower ranks.
Endothermic Tag
Rank: C, B
Better known as a "Hyouton" tag, endothermic tags rapidly absorb heat within a radius of the tag. The heat is converted to chakra and can be channeled to another tag. The sudden heat removal results in rapid freezing of surrounding material. Hyouton tags are generally used in the manufacture of exothermic tags (Type II* Burn, Type II* Omni, Type II* Directed, Type IIID-S * tags).
Arc Tag
Rank: C, B
Arc tags hold a reservoir of chakra that it converts to a Raiton bolt that arcs from the tag to the target when activated. If arc tags are deployed in pairs, the Raiton will bounce between tags in a sustained arc until something interrupts the circuit.
The most dangerous type of combat tag, Type III tags are used to destroy non-living targets such as supplies, buildings, or bridges. Use of Type III tags without sufficient training is highly frowned upon and negligent use can result in severe punishment due to the sheer destructive nature of these tags. Also because of that, all Type III tags above D-rank are barred from exams, spars, and tournaments unless explicitly stated otherwise. The use of Type III* Demo tags without certification is often a punishable offense.
Practice Tag
Rank: E
These E-rank tags simulate the other Type III tags for training, practice, and competitive use. They appear and act exactly like the regular Type III tags, but the fiery death element has been replaced by colored smoke or paint. This allows ninja to practice and train on use of the tags without placing themselves in mortal danger. While these tags are supposed to be clearly labeled on the seal side with marking that visually indicate practice seals, some instructors have those left off for use in tests so the student will think it is a live tag.
Breach Tag
Rank: D, C, B, A
Breach tags serve as explosive means to create an entrance or surgically demolish a structure.
The D-rank Breach tag is fairly thin in design and can be looped around objects easily. It provides an omni-directional explosion, and is generally used to break through thin military walls or most civilian walls up to medium thickness.
The C-rank Breach tag is wider than the D-rank tag and is primarily used on flat surfaces such as walls, floors, or ceilings. This tag focuses most of the explosion in the direction opposite the seal side. It can blast through most non-bunker military walls and nearly any civilian wall.
The B-rank and A-rank Breach tag acts like a Type II Omni tag, but a magnitude in strength higher than its same rank counterpart. This tag's primary purpose is to breach re-enforced walls and blasts holes into bunkers.
Thermite Tag
Rank: D, C, B
Thermite tags are used for the destruction of supplies, weapons, and just about any other materiel the enemy has. Thermite tags
act similiar to Security tags, but have a far higher temperature to their fires. These tags get a larger radius as the rank goes up.
Demolition Tag
Rank: B, A, S
Demolition tags are designed for the sole purpose to destroying structures. Given that most structures a ninja would need to destroy will likely be extremely sturdy or re-enforced, demolition tags exist solely in the B-rank to S-rank power range. Multiple B-rank tags are sufficient to destroy most civilian structures while a single S-rank tag is generally sufficient to destroy the inside of a medium sized bunker. These tags are known as "demo" tags or generically as "bunker busters."
Support Tags are similar to Type I tags in that they're non-lethal, but Type IV tags are used solely in conjunction with other tags. This is also the only other category with tags available at every rank.
Trip Wire Tag
Rank: E
Trip Wire tags are deployed in groups of two or more. Each tag is connected to one or more other tags using chakra string connections. When the string is tripped, chakra in a small 'reserve' seal within the tag is released to attached tags. These are typically used with Type II or Type IV* Drain tags.
Timer Tag
Rank: E
The basis for the Type I Alarm clock tag, the timer tag operates in the same manner except that it releases the 'reserve' chakra to attached tags rather than turn it into Raiton and jolting what its attached to. These are most commonly used with Type III tags.
Deadman Tag
Rank: E
This tag is fed chakra to activate it, which pools in a 'reserve' seal. Once the reserve is filled, the excess 'bleeds' off. Should the chakra feed stop without first draining the reserve seal, the chakra in that seal is released to activate attached tags. These are generally used with Type II or III tags concealed on a person, or with a Detonator tag.
Remote Detonation Tag
Rank: E, D, C
Remote Detonation tags are linked to a Detonator tag when primed. When the detonator tag activates, it causes the remote detonator tag to release its stored chakra to attached tags. Higher rank gives a longer range the Detonator tag can work in.
Sequencer Tag
Rank: E, D, C
Sequencer tags are a combination of remote detonation tags and detonator tags. They serve to ensure detonations happen in a particular order. They are usually started by a remoted detonation tag. Higher ranked sequencers can be further separated from the previous tag in the sequence and still work.
Detonator Tag
Rank: E, D, C
One of the few tags that can conceivable be used multiple times, a detonator tag is linked to a remote detonation tag when primed. On activation, it activates the linked remote det tag. Higher rank means further working range though, due to range limitations of remote det and detonator tags, the detonator tag should be of equal rank to ensure the tags can receive the activation order. If the two ranks are not equal, the tag with lower range provides the activation range limit.
Endochakra Tag
Rank: E, C, B, A, S
Endochakra tags drain chakra within range of the tag. The drained chakra is then funneled to attached tags. The E-rank version is used to drain chakra from primed tags. The C-rank version has a radius of 2m, while the S-rank has a radius of 8m. Generally accepted practice is that a single tag should be able to drain most of the chakra from an opponent of rank equal to the tag. In use, the tags usually act to stall opponents just long enough for the tags it powers to activate, and the rule of thumb in that case is to use a tag of at least one rank below the highest rank opponent be planned for (use C/B-rank for Chunin, B/A-rank for Jounin). These tags can cause chakra exhaustion or death.
