If anyone needs help with character creation, just let me know.
Txosuè, your character has a Staff of Withering? I don't think that's among the starting equipment for a warlock, since it's worth north of 5,000 gold! What feature gave you that? Regardless, you might want to find a ranged weapon that suits you to make your pact weapon, since your AC is 11 and you'll be pretty squishy to be crowding into melee.
