In order to grow your seed, you must complete three tasks. With each task, it will gain strength to grow. By the second task, it will be able to help someone with a specific affliction. By the third task, it will be able to help them overcome it.

If your team wishes, you may exchange your seed for another after completing a task, choosing between the two seeds left. However, you will only be able to finish two tasks for your new seed. Please, ask in this post and ping me if you would like to switch. ♥
