The Saltysweet

This pact will haunt you. You have always had this nagging voice in the back of your head whenever something went wrong and now you know why. A mysterious entity seems to follow your life and lends their comment to your exploits. Since you started to grasp the meaning of the entities mutterings you can feel the salt in your very soul. However, your patron also seems to energise you at times. In these moments you feel power coursing through your entire being and you know that you have never been quite so awake before. 

The bottle of E'mmi

Soothing Energy

As an action you can take a sip from the bottle you received from your patron. You instantly recover [roll]1d6[/roll] + CON modifier hit points. You also radiate a 10ft aura of relaxation that lasts for 10 minutes. If you make an attack roll or damage an enemy the aura vanishes. As long as your aura is active everyone inside of it is under the effects of a Sanctuary spell. 

 

Explosive Energy

As an action you can take a sip from the bottle you received from your patron. The moment you swallow, a wave of destructive energy wafts out from you in a 10ft radius. Everyone within the area of effect has to make a Constitution saving throw or take [roll]1d10[/roll] force damage and be pushed back 5ft. Your movement speed also increases by 5ft for the duration. This effect lasts for an hour or until you spend a turn doing nothing. Being unable to take a turn does not count as doing nothing for this instance.

Hot or Cold

As the caffein becomes part of you, your body adapts to these changes. After finishing a long rest you can choose to receive resistance against fire or cold damage as you decide wether your patrons bottle contains fresh hot coffee or iced coffee. No matter what damage type you choose, you also receive resistance against the effects of cold weather. Furthermore you can no longer be put to sleep against your will.  

Errupting Life

When you are reduced to 0 hit points you do not fall unconscious, instead a cloud of foul gases and salt rises from your posterior. Each creature within 15ft of you takes [roll]2d10[/roll] poison damage and [roll]1d10[/roll] piercing damage as the gases fill their olfactory organs and the salt pierces their skin, no matter how thick it is. You can use this feature once per long rest.

I am speed or maybe not

As a bonus action you can give yourself the benefits of a Haste spell requiring no concentration. As an action you can give that effect to a companion you touch as you have them drink from your patrons bottle. After the effect ends, you do not suffer the consquences of the Haste spell. 
You can, however, also choose to use your bonus action to put an enemy you can touch - this also applies to incorporeal foes - under the effect of a Slow spell, no concentration required. There is no saving throw against this feature. 

You can use this feature a number of times equal to half your proficiency bonus per long rest.
