Giant, Stage 1

Giant Form. Your Strength score increases by 2, to a maximum of 22, and your Constitution score increases by 2. Your creature type becomes Giant. Spells and abilities that affect giants of a specific CR have no effect on you.
Growth Spurt Your body swells as muscles grow and bones elongate, a painful transformation that ends in a towering stature. If your size is smaller than Large, it is now Large. In addition, your maximum hit points increase by 5 and increase by 5 again each time you gain a new Giant transformation level. Your new larger size does not change your weapon damage.
Flaw.
Big Appetite. As your body has grown, so has your appetite. While you once subsisted on a few pounds of food a day, you now must eat one livestock animal a day to feel nourished. You must eat at least 2 gp, or about 200 lbs., of food each day. You cannot gain the benefits of a long rest on a day where you have not eaten enough food. 
Heavy Soul. Your gigantic size extends to your soul as well, making it heavy and burdensome to call back from the beyond. When a creature attempts to return you to life using revivify, raise dead, or a similar spell or effect, it must provide material components worth twice as much as the spell specifies.
Giant Size. Due to your enlarged size, any weapons and armor that are not stated to adjust to your size must have barding rules applied to crafting and purchasing.
