Thrower

Due to your sheer size and strength, you've gained the ability to throw grappled creatures at a wall, the ground, or other enemies instead of your normal attack roll.

• You may use your action to throw a grappled creature at nearby terrain like a wall, ceiling or even another creature. If the grappled creature is a bigger size than you, you're unable to throw them. If the creature is the same size, make another grapple check. If you succeed, you can throw them. If the creature is at least one size smaller than you, no grapple check is required.
• Throwing a creature who is willing to be thrown will not require another grapple check. 
• If you successfully throw the grappled creature, they take damage depending on what your size is. 

The damage the grappled creature takes is equal to 1 dice rolled of your size's dice type for every 20ft. the creature is thrown + your Strength modifier. If you throw a creature into another creature, the second creature takes damage based on the thrown creature's size dice + your Strength modifier

If the thrown distance is lower than 20ft., the attack will simply deal 1 of your size's dice + your Strength modifier as damage.

The damage type is dependent on the surface/creature the grappled creature hits, being bludgeoning damage if it is a solid wall or another creature, or piercing damage if the creature is, for example, covered in spikes.

Your max throwing range is equal to (60 + 5 × your Strength modifier). If the grappled creature's size is the same as yours, you can only throw them half as far.
