Horizon Forbidden West 009

Video showing some parts of the Seeds Of The Past quest. Aloy at the end has the Vinecutter and already owned the Igniter. Two special gear items that come in handy while exploring the Forbidden West. in Ruins and other special locations not having these special gear items can prevent you from completing the task/quest for that location.
To make the following clear: Seeds Of The Past is a quest not in the very first part (map) of this game, but much further on, after Aloy has established a base in the mountains. You will run into ruins/places where you need the Igniter and/or Vinecutter, but you will only get those special gear items later in the main quest line. So, don't despair when you don't have these special gear items yet.
