Magnet Release
Are all in. Magnet Release and Medic are not 100% finished but are playable and complete enough to be competitive.
Snake DNA is currently being worked on and is almost finished.
Clay is in some stage or another of being worked on and will be finished sometime in the future.
Since Copy Ninja is mostly other jutsus all the resources for it are technically iconned and coded, but the clan still needs a skill tree and other work before it's released and probably won't be out for awhile.
Nothing's really started for Senju.
Tai specialist has jutsus planned out but I'm not sure how far along any other work for the clan is, so don't expect anything for awhile.
Nara and Spider were in before but require reworks to be updated for the newer systems.
All of the requirements are accurate.
