How about some anti-God Giant warlocks?
Somehow you now work exclusively against the gods be it from loss or anger. This has lead to other patrons noticing you. Chief of among those is Gaea. Having lost her first creation, she now works behind the scenes choosing those she finds worthy to help hear giant children retake heaven!
Expanded Spell List
Gaea lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.
|2nd||enhance ability, barkskin|
|3rd||Meld into Stone, Counterspell (divine magic only)|
|4th||Stone Shape, Stoneskin|
|5th||Conjure Elemental (Earth Elemental only), Wall of Stone|
Starting at 1st level, you gain advantage against all spells and effects from divine creatures and all divine spells and effects have disadvantage to hit you.
Starting at 6th level, you can no longer be killed while on ground and without divine help. If you die on natural earth (ground that is not process to become a street, stone not made into fortress or man-made caves, or earth not made into farmland) you instantly stabilize. You only begin dying if a non-magic weapon and a divine spell both attack you in the same turn and you are taken off the natural earth. This power functions on the elemental plains, but does not function on other planes.
Gaea’s Dark Protection
Starting at 10th level, up to a number of times per day equal to your Charisma modifier, when you cast a spell and are directly standing on natural earth you may draw power from Gaea and cause the spell to be affected bye empower spell as a Sorcerer’s ability.
Starting at 14th level, Gaea blesses you with a few drops of the last true giants blood. You fall into a trance for 24 hours after which your type changes to giant, you be large, your Constitution, Strength, and Charisma increase by +2, to a maximum of 22. All gear you had when you entered the trance is now sized for a large creature, but you weapons do not deal extra damage. In addition, you feet become snakes you can walk upon. It does not change your speed, but as a melee spell attack with which you are proficient, you may attempt to attack another target as an action dealing 3d10+Charisma modifier poison damage to the target.
