Quick note here, I also noticed that part of the Mobile feat (No foe opportunity attack if you hit that opponent that round) only works about 50% of the time. Sometimes the Mobile feat user can get away with no opportunity attack, and sometimes they still get smacked even though their attack connected on the enemy moments before. In each of these examples, the attack connected and the foe had the Mobile Foe status effect, before trying to move away from them.
Keep up the good work ^_^
