I had a college professor that teaching was his fourth career, he was in his 90s. He started the first class of each term with "I'm not going to remember any of your names. I'm old. My brain can only hold so much. If I put your names in my brain, something else will fall out. It might be my wife's birthday, it might be that I need to take about a hundred pills a day. Either of those, and I'm dead by next week."
It’s so hard for me to remember peoples names. I gotta associate something they do with what their name sounds like to stand a decent chance. It’s honestly nothing personal either. I’ll remember everything else you say and do but for some reason, not your name.
Just armor and also can't cast spells. And they changed it to "Armor Training" now, but still proficiency for weapons? And the Martial Weapon Training feat gives you Martial Weapon proficiency? Gah
If you wear armor that you lack proficiency with, you have disadvantage on any ability check, saving throw, or attack roll that involves Strength or Dexterity, and you can’t cast spells.
