Density

You can painfully concentrate the very matter of the universe around you into your body, increasing your density and weight up to 1,000lbs. Use creatively. Your limbs become egregiously heavy making walking, striking, and casting spells extremely difficult. Jumping is impossible and your movement speed is reduced by 25ft. However, your newly hardened body bolsters a + 5 to your AC and a + 1d10 temporary hit points. The magical properties of this spell prevent you from becoming completely immobile or prone. When you attempt to Dispel Density, you must succeed on a strength saving throw DC: 15, or else you cannot perform the somatic movements properly and will remain in your current state. The only means of removing Density is by dispelling it. 

You gain the following Properties from Density:

• + 1d10 Temp HP
• + 5 to your AC
• - 25ft of Movement Speed
• - 3 to attack rolls and disadvantage (Including Spells only if your Spell is Somatic)
• + 1,000lb's in bodyweight
•  You can only jump off the ground in inches equal to your Strength Modifier
