Obtainment: Kill any main arena boss, get the trophy and moss. Put them into the cave altar and get the ESSENSE OF NATURE. Your screen fades black and text saying „Spread nature, my child” appears. Screen becomes normal and the cave area turns green. You need to spread nature on all the unnatural surfaces on the map. You get ragdolled into the grass and sink into it and become one with nature.

Abilities
(UPDATED) Passive - Uprooted: The vines now have an increase in length and width and you can grab onto more objects (e.g. Anchored Engineer builds) and you have no legs since that's where the vines will come from. No delayed turning.
(NEW) [E] - Tentacle shot: You shoot a tentacle from your arm that goes 20 studs/s. If it grabs onto a person it latches on them and does 5 damage and slows you down. The tentacle stays attached to a person and keeps them in normal speed in a 10 stud radius. If they go past 10 studs they get slowed down to 5 studs/s, until at 12 studs the tentacle snaps letting the person go. The tentacle stays for 10 seconds. Cooldown doesn't start until the tentacle de-spawns. CD - 2 seconds.
(NEW) [Q] - You release 3 small clouds of gas that have a radius of 2 studs around you that do 1 dmg/tick. The gas lasts for 20 seconds. CD - 30 seconds
(NEW) [R] - Sprout: You spawn 3 homing spores which home onto the closest player and 5 tentacles coming out of you. The spores do 5 contact damage and de-spawn on hit. The opponent can punch the spores to de-spawn them immediately. CD - 30 seconds
Looks
You have pink petals surrounding your head/neck like a collar.
