The Ouroboros

Amid the wild and powerful magics that are used among this land, it is not surprising that one would discover the ability to manipulate time itself... at some point in the future. In this modern age however, the denizens of the world must make do with what they have... or what is offered to them by those from the future.

Sometimes at the low point of their lives, or at the moment before a tragedy, some have said to have been visited by a mysterious benefactor; the individual varies per case, but they all seem to have a common goal: to keep the person at risk alive and well. The reason for this, few can guess.

Was your character in a similar situation? At the lowest point in their life, willing to end it all? Or maybe looking down the blade that would spell their demise? In any case, they were visited by someone whose goal was to save them from this point in time: someone who knows more about them than they should. This person had a simple proposition for them: they would be saved from their current situation via this mysterious individual, but their life mustn't go to waste; they are charged with becoming stronger, better, all around more powerful than they are now. But most importantly, they are to remain alive. They would be offered some of the power to do this, but the rest must come from their own experiences and travels.

Now, unbeknownst to the character, this mysterious benefactor is actually themselves, from the future. They are one of the few individuals who have actually learned the ability to manipulate time to their will, and they used it to save themselves from the struggles they faced in their younger years. How this manifests is up to you and your DM, but the basic principles lie here.

Memories from the Future

6th-level Ouroboros feature

When you make an ability check, weapon/spell attack, or saving throw you can give yourself advantage on the roll, as your benefactor tells you how to succeed. This may be an auditory voice stating a quick command, or a mental whisper giving a short snippet on how to accomplish the task in front of you. Once you use this feature, you can't use it again until you finish a short rest.

Temporal Alertness

10th-level Ouroboros feature

Whenever a creature attacks you, regardless of if you can see it or not, you can use your reaction to completely evade the attack as your benefactor informs you of it. You may immediately make an attack against that creature as a part of the same action if it is within your weapon's range.

Once you use this feature, you can’t use it again until you finish a short rest.

Timely Intervention

14th-level Ouroboros feature

When you would be reduced to 0 hit points, your benefactor appears, seemingly out of thin air, and prevents you from the damage. How this happens is up to the discretion of you and your DM, but it could look like one of the following ideas: your benefactor materializes and pushes you to away from a deadly blow before disappearing just as quickly as they came; your benefactor appears and stops the sword of an enemy who was about to slay you, providing you time to escape before they vanish again; your benefactor casts a spell that would protect you from a devastating attack, or counters an enemy's spell that would otherwise cause great harm.

Once you use this feature, you can’t use it again until you finish a long rest.
