Can a warlock summon a Dao’s maul or a Storm Giant’s greatsword as their pact weapon?

Could a “High” Elf with a criminal background use “mage hand” with their tools and skills?

What are your thoughts on converting Humanoids from the Monster Manual to PC races?

If I use Ready to make an attack with a reaction, can I also take an associated bonus action e.g. Flury of Blows?
