Giant Ancestry

At 1st level, you choose one type of true giant as your ancestor. The type of giant is used by features you gain later.

You can speak, read, and write Giant and gain proficiency with shields and simple weapons. Additionally, whenever you make a Charisma check when interacting with Giants that are the same size category or smaller then you are, your proficiency bonus is doubled if it applies to the check.

Jotun Resilience

The resilience of giants flows through your body. At 1st level, your hit point maximum increases by 1, and it increases by 1 again whenever you gain a level in this class.

Additionally, your skin and bones take on the toughness of true giants. When you aren't wearing armor, your AC equals 10 + your Dexterity modifier + your Constitution modifier.

Mark of the Ordning

At 1st level, roll 3d4. You grow a number of inches in height equal to the roll.

When you reach 3rd level in this class, you learn the Enlarge/Reduce spell, which doesn't count against your number of sorcerer spells known. You can cast it by spending 2 sorcery points or by expending a spell slot. If you cast it with sorcery points, you can cast it as a bonus action and it doesn't require concentration to maintain but you can only use it to enlarge yourself and it cant be affected by your metamagic feature. If you cast it this way, you can use an action to end the spell early, it also ends early if you die or are incapacitated.

Soul of Lost Ostoria

Starting at 6th level, you gain a benefit tied to one of the true giants. You can activate the benefit as an action and it lasts for 1 minute. You regain the use of this feature upon finishing a short or long rest. While under the effects of the Enlarge option of the Enlarge/Reduce spell, your benefit is always active.

Cloud Giant. Your body feels light and cloud-like gasses exude from your body. Whenever you cast a Sorcerer spell and expend a spell slot, you can magically teleport as a bonus action. You can teleport to an unoccupied space which you can see that is no farther away than a number of feet equal to 5 * your Charisma modifier (minimum 5 ft.). If you are casting a sorcerer spell that would allow you to teleport, such as the Misty Step spell, you can instead add this bonus to the range of which you can teleport.

Ettin. When you turn your head it seems as if theres an illusion of it that turns the opposite direction and when you speak your voice sounds as if theres two of you speaking at once. You gain a bonus to Wisdom (Perception) checks and on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious. The bonus equals your Charisma modifier.

Fire Giant. Heat radiates off your body. Once per turn, whenever you cast a Sorcerer spell that deals fire damage and expends a spell slot, you may add your Charisma modifier (minimum of 1) to one of the damage rolls. If the spell applies damage over multiple turns, you can reapply this damage to it.

Frost Giant. The cold clings to you like blanket. Whenever you cast a Sorcerer spell that deals cold damage and expends a spell slot, you gain temporary hit points equal to your Charisma modifier (minimum of 1).

Hill Giant. As you cast, an invisible force pushes everyone around you. Immediately after you cast Enlarge/Reduce or cast a Sorcerer spell and expended a spell slot, every creatures within 5 feet of you must succeed on a Strength saving throw against your spell save DC or be pushed a number of feet away from you equal to 5 * your Charisma modifier (minimum of 1). A target can choose to fail this save.

Stone Giant. Your skin becomes as hard as stone. As long as you're not wearing armor, Whenever you cast a Sorcerer spell that expends a spell slot, you gain a bonus to your AC equal to your half your Charisma modifier (minimum of 1) until the end of your next turn.

Storm Giant. Lightning courses through your veins. Whenever you cast a Sorcerer spell that deals lightning or thunder damage and expends a spell slot, up to three creatures of your choice that you can see within 30 feet of you take lightning damage equal to your Charisma modifier (rounded down to a minimum of 1).

Titan. You feel an immense amount of inner strength. As an action you can slam the ground causing a great tremor, every creature within an area around you within a number of feet equal to 5 * your Charisma modifier must make a strength saving throw against your spell save DC or be knocked prone.

Rage of Fallen Ostoria

Starting at 14th level, you gain the ability to channel the souls of your ancestors into your physical form. When casting the Enlarge option of the Enlarge/Reduce spell, or when you start casting a sorcerer spell and expend a spell slot while already under the effects of the Enlarge option of the Enlarge/Reduce spell, you can increase your size by one additional size category – from Large to Huge, for example. This increase ends early if you die or are incapacitated. For the remaining duration of Enlarge/Reduce, you gain the following benefits:

• Your current hit points and your hit point maximum both increase by 1 per sorcerer level.

• Your reach increases by 5 feet.

• Your walking speed increases by 5 feet.

• You gain a bonus to your strength checks, strength saving throws and to the damage rolls of your melee weapon attacks; the bonus equals your Charisma modifier (minimum of +1).

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

Giant Ancestry Spells

reason for homebrew

Ive seen the Giant Soul in action and it seems built to make a melee sorceror for both flavor and some of the mechanics, so I thought about retooling it so it has tools to actually do that. I ened up copying the draconic sorceres first two abilities since they just matched giants so well.

Giant Ancestry and Jotun Resilience

On top of the HP boost, you speak Giant and can use all simple weapons. If a dragon sorceror and storm sorceror learn draconic and primordial just because then why not giant? Simple weapons if to give users a half decent weapon to use since giants are all about walking up to someone bashing them into the ground.

Mark of the Ording

I removed original Ording spell system and replaced it with an expanded subclass spell system. I made Enlarge/Reduce the star of the class however, making it so that it can be cast with sorcery points and as a bonus action, all without concentration.

Soul of Lost Ostoria

Replaced the Ordning spell triggers with an action that last rounds equal to twice you con mod and is active automatically with under the effects of Enlarge/Reduce. I originally had it so that they only worked while enlarged but I figured that could be awkward always having to burn a resource sorcerors already have few of everytime just to use a key class feature. I also changed some of the effects so that no longer worked some of them relied on the Ordning spells. I also added a bit a flavour on how I saw each ancestry manifest.

Cloud Giant: Changed it to whenever you cast a Conjuration spell since its a teleporting effect. Also made the distance equal to 5 * constitution modifier since 10 + con just means 10 or 15 feet.

Fire Giant: Unchanged except that the trigger.

Frost Giant:Unchanged except that the trigger.

Hill Giant: I removed the limit of 2 creatures and made distance a multiple of your Con mod instead of an addition for the same reasons as the cloud giant.

Storm Giant: Unchanged except for the trigger.

Ettin: I gave the effects from the Ettins Two Head feature but with a bonus instead of advantage, since its the only thing separating the Ettin from being just a weaker Hill Giant. I figured it could be flavored like you have two minds at once but both are you so there doesn't need to be a split personality situation happening (unless you want it too).

Titans: I gave them a ground pound ability since their most recognisable trait is that they are BIG (-ger then every other giant), so I figured that if they were to stomp the ground it would be like a mini earthquake. The Empyrean, which is the closest monster I can find to the Titan in 5e, has this ability and it seems fitting.

Rage of Fallen Ostoria

I made it that you needed to be enlarged already to use this ability. If you look at how the giant stat blocks are made, a large creature like an Ettin or Troll only have 5ft reach with attacks while huge Giants have 10 ft reach, thus I thought it fitting that you only get the reach increase ( among the other bonuses) when already Enlarged. In theory a medium creature would end up be huge.... but small races like a halfling would only be large and get the reach, but theres only so much I can do without overcomplicated the ability with every possible scenario.

I also gave a bonus to strength checks and strength saving throws since Enlarge already gives you advantage and when your that big your bonus should start resembling that of actual giants.

Blessing of the All Father

Made the bonus to strength checks, strength saving throws and damage bonuses cumulative. At level 18 things are supposed to get crazy.

Giant Ancestry spells

For DMs that like to give Sorcerers subclass spells, I added some for each giant bloodline. This was hard to do because I originally wanted one list for all types but since the different giants are mostly giant bags of hit points with little magic or abilities tied to them compared to dragons, I had to make separate lists for each to draw on the few unique things of each.

Luckily I managed to figure out a list of spells that work for all giants, makes making specific lists easier.

For the spell swapping mechanic introduced in Tasha Cauldron of Everything, I choose transmutation because theres a lot of physical transformations in the subclass, and divination because it's meant to as spiritual as well as pure magic.

Catapult is on all of them to simulate rock throwing (Ettins don't get that attack but no other 1st level spell works).

Glyph of Warding Because Runes.

Staggering Smite Because if a giant hits you with a big stick, your going to be staggered.

Bigby's Hand A giant hand that can do stuff, seems fitting.
