Right back to the glaive with this one, in addition to separating the Glaive and Kinsect, they also split how you feed it and with what, you have the Growth nectars, for power, speed and stamina but you also have the elemental nectars, The kinsects will only level to a max of Level 8 we they can be fed a total of 3 more levels worth, it also shows you what the levels are on the kinsect as well as the points and finally NO MORE DAMNED MATH GAME, yup Power no longer affects speed, speed no longer affects stamina and stamina no longer affects Power, they are just seperate things now.
Onto Kinsect forms we have a total of 5 base forms, the original Base form, the Power Form, the Stamina Form, the Speed form, the first three Forms become unlocked at Kinsect Level three and gain two more forms available (a note here once you choose say Power, YOU CANNOT GO ANOTHER ROUTE) these two new forms will unlock at level 6 and which ever you pick is your final choice, the final base upgrade is the Balanced Upgrade this requires level 6 as well so YEEEEEEEEEEEAH and it doesn't have an upgraded form
Aside from Kinsect all the nectars appear to be available for trade as well now, after a certain point in the storyline you can multiply them much as the wycoon can multiply shrooms and the like, Bare in mind you must find one at least of each type, Also a specific plant will have Nectars.
