I wrote some stuff for a upcoming thing! Here are some things I liked, but didn’t make the cut. Here is a Warlock pact. Its a scary one!
Shell of the Master
Every master chooses those who can serve, and you have been chosen for a most glorious purpose. Something happened, you do not remember much, but there was blood and pain, and now you feel the master in you. You are the now the harbinger of the master. The master grants you power to protect his or her investment. Soon the master will choose you for his final purpose and you will be given the most precious gift of becoming one with the master!
Table: Shell of the Master Expended Spells
Your master provides several extra spells that most warlocks do not have access to. The following spells are added to the warlock spell list for you.
Table: Symbiote Expended Spells
||Cure Wounds (self only), Shield
||Barkskin (self only), Enhance Ability (self only)
||Protection for Energy (self only), Haste (self only)
||Greater Invisibility (self only), Stoneskin(selfonly)
||Modify Memory, Contagion
Starting at level 1, the master has granted you withhis investment a measure of protection. A number of time per day equal to your Charisma modifier, you can cast shield without using a spell slot or using your reaction for the round. You need not have shield prepared to cast this spell.
The Child Quickens
Starting at 6th level, you feel something the child growing inside you, and your “soon to be born child” begins to help its vesselvesile. A number of times per day equal to your Constitution and Charisma modifier you may gain advantage on a saving throw.
Share the gift
Starting at 10th level, you have begun to grow to bulbus lengths as the child begins to grow and squirm inside of you and throughout you. Once per day you may grab a helpless humanoid with less than 20 hit points and kiss that creature on the mouth, expelling your master’s children into the creature. The creature must attempt a Constitution saving throw. If it fails, you have filled the creature with your masters spawn. The creature is affected by dominate person for 1 minute requiring no concentration. Once the spell ends, the masters spawn hatch and the creature explodes in to a shower of gore and you summon forth a creature of CR 2 or less of your master’s chosen type. The summoned creature is not under anyone’s control and acts according to its own will except to not attack you. All creatures who witness the effect must succeed on a Wisdom saving throw or become frightened for one round. You may do this once per day and must take a long rest before you can reuse this ability.
When you reach 14th level, the master has arrived! You explode into a shower of horror and the master’s true child steps forth from you ruins of your body. You are utterly destroyed and only a wish spell can restore you to life. Choose a creature of your master’s type with a CR of 7 or less that your master would approve, at GM discretion. You are now this creature. You gain all the powers of the warlock class you had as well as all abilities from your new class. You may retrain any ability increases using the creatures base statistics, and you are no longer limited to having a maximum of 20 in any statistic. The DC of any special abilities is equal to your spell save DC and any special attack of the creature is treated as a melee spell attack that you are considered to be proficient in. You continue to level as a warlock from this point forward as you are still being guided by the master in this new form.
