I am not sure if this is intentional but I La'zel has a proficiency bonus to attack of a +2 at level 3 instead of a +3. I am curious if the Proficiency bonus of others is messed up as well. I have not had the time to being any fighters or rangers up to 3rd and 4th level since the patch.
Also I just did the phase spider fight and only got 20 xp for the fight. Seems a bit low to me but I have not been paying that great of attention to the xp per fight.
