Awaked Fury of Zehir

Your inner fury burns tirelessly. You gain the following benefits:

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• When you hit with an attack using a simple or martial weapon, you can roll one of the weapon’s damage dice an additional time and add it as extra damage of the weapon’s damage type. Once you use this ability, you can’t use it again until you finish a short or long rest.
• If you drop to 0 hit points & enter an unconscious state, you instead drop to 1 hit point. Following this, as a reaction, you can untether Zehirs influence & release a relentless force of Psionic energy. During this reaction, you are able to dash, your AC becomes 25 & you can make a number of attacks equal to your dexterity modifier. Each attack deals an extra 4d8 lightning damage & you deal 4d6 lighting damage to anything within 5ft of you if you use the dash action. 

As your understanding of this power grows, so will it’s severity…
