Summoning: Stinger Modification Technique

The Kuchiyose: Dokubari Henkou no Jutsu (Kanji: 口寄せ ・ 毒針変更の術; English: Summoning: Stinger Modification Technique) is a personal favorite of Oshiishi Kamizuru.

After Oshiishi performs the necessary hand seals, he will summon a swarm of a particular species of bees. Each of the swarm's constituent bees will be fully capable of absorbing and transferring chakra. Thus allowing the swarm to be utilized as a means of allocating chakra to those allies whom are in great need of it.

However, as a direct result of having been summoned through the use of this jutsu, the stingers of the aforementioned bees will no longer implant bee venom into that which is stung by them. Instead, they'll implant a poison of Oshiishi's own design. This will allow Oshiishi to utilize the bees as an efficient means of poisoning his foes with whatever poison he desires. Oshiishi can also have the bees implant medicine as well in order to quickly distribute antidotes throughout a battlefield.

Because the sheer quantity of bees that Oshiishi is capable of summoning at a time, Oshiishi's use of this jutsu has become rather infamous over the years.
