I'm playing a Goliath Barbarian, focusing on the inherent grappling advantages. I'm trying to pull as much benefit from Powerful Build as possible. My specific questions are:
Considering my Goliath can lift over 2000 pounds, can I just lift an enemy above my head?
If I can lift this enemy, does it require a second grapple check to do so, or can I just do it if I still have him grappled when I attempt it?
Since I am eight foot tall and holding this enemy above my head with my long arms likely extending to at least 10 feet, will the enemy being dropped cause 1d6 fall damage?
Is my movement impaired while moving with a grappled enemy that I have lifted from the ground, or is it not since I'm below my carrying capacity of 1000 pounds?
If my movement is impaired, could I just throw this person as an improvised weapon up to 20-60 feet? Could I throw this individual vertically for 6d6 damage?
Could I actually use this person as an improvised weapon? If I could, would his similarity to a weapon be a greatclub for 1d8 damage? If I swung this improvised weapon at a person, would it deal 1d8 damage to both people or just the person being hit? Could I also throw this person at someone else for 1d8 plus 1d6 for coming from a height above 10 feet (overhead toss)?
This is where RAW tears severely against logic/reality. I could eventually see myself having a lifting capacity of 5 tons through enlarge + enhance ability, but not be able to toss a halfling across the battlefield.
