What class/subclass for a 5 year old who is not a strong reader

[follacchioso]

Paladins are also an easy class to play. Champion fighters are easy mechanistically but paladins are easier to role play. Just explain them the role of conduct for their oath - be a good guy, don't lie, be brave - and that will give them an idea of what to do and how to interact with the others.

In combat, a paladin can just swing the sword and use the smites against the strongest enemies. This is something easy to learn, which has a dramatic effect when used. Paladins can prepare other spells but there is no need to learn them in details at the beginning.
