How large is it possible for a PC to get?
For clarity, here are my parameters:
- This is about size categories, not 'feet' or 'inches' or 'meters' or any other precise measurement. This is about Medium to Large to Huge to Gargantuan categories.
- This is for an NPC charlatan using this to trick people. (It's an NPC but will have a full PC sheet, so the distinction between PC and NPC doesn't matter).
- Any means of size category enlargement works for this purpose, including magic spells, magic items, etc. Illusions do not count because it's about actually becoming larger, not just casting an illusion of a gargantuan giant version of yourself.
- The character must remain the same physical structure. Polymorphing into a Gargantuan Dragon would not satisfy the need here.
- Consumable items are fine.
- This does not need to be permanent.
