Can someone explain me how to make this Botanit quest?
Can you explain what you mean are you trying to do this quest? If so there are Root guardians every 15 floors in the dungeons listed they are rather hard so make sure you are powerful enough to do it. I have heard some comments state they had trouble getting the quest to update or something once you'd have to look through the comment section here to find it. Sorry I can't be much help I've not even done that quest ever myself.
In the skill tree there is a skill you can get called bite the kobolds in the crystal cave use this if you interact with the green liquid vat behind the Lich you can become one and will get his tentacle and goo sphere weapons for free the orb can steal too but the bite move is permanent from what I read then there's the weapon rock sword it will take stats from those hit and add it to you but you can't get AP when using it. Those are the only ones I know of. I can try to help more but I'm stuck trying to level up and none of the companions are growing after I fight them Beast seems fine though.
