IRL? anything that isn't melee since you're basically gambling whether or not your opponent is more skilled/experienced than you. its better to fight dirty with stuff like pocket sand and throwing knives from a distance and its easier to flee since you aren't as commited to the fight in terms of relative distance to your enemy, there's also lower chance of injury which takes time to heal and probably will need profesional help that requires $, etc... NON-IRL? doesn't matter since its varying degrees of asspull, it's fiction and unrealistic, a pure melee character will somehow win against a god able to kill everything with a thought lol.
