What is DNA?

DNA serves to implant all the natures or Kekkei Genkai which exist in the version of the mod which you possess.
How to identify?
To identify you need a minimum of 20 of Intelligence but, with more intelligence you have a higher probability of identifying it. (This probability capping off at 70%)
When you click on it one of three things will happen :
1) You fail and the item is destroyed (in low levels it is more likely to happen )
2) You obtain a Nature Release
3) You obtain a kekkei genkai
How to inject?
After you identify your DNA you can inject it in yourself by Right Clicking with the item in your hand or to hit a person with the item to implant it in a player (you need a minimum of 300 in medicine for implant it into yourself and 400 to implant it in a player; and with higher medicine you have a higher probability of success)
When you use it one of three things will happen
1) You fail and the item is destroyed, and you are poisoned
2) You fail and the item is destroyed, and you die
3) You succeed in injecting yourself and you gain the Nature/Kekkei Genkai
If you successfully gain the power of the DNA your body will need a day of rest and you will be given 20 minutes of slowness,weakness and mining fatigue along with 1 minute of nausea (and if it is dojutsu kekkei genkai then you will also have 20 minutes of blindness as well)
