Oof. I forgot about GoOP/HoI. Those are kinda game breaking if you are allowed to design your build around them.
I hate being that DM but, I'm going to have to ban GoOP and HoI as starter items. They are just too optimizable. It's one thing to come across them randomly, but when making a "build" they are just too good.
If you REALLY want strength boosting Gauntlets, I'll allow Gauntlets of Bugbear Power, +2 Strength, Max 17 Strength.
Also, not that I really care, but if you are researching enough about the dwarves of Mirabar to worry about the last name, you'd also need to account for his family not being native to Mirabar. The dwarves of Mirabar, and the rest of the Sword Coast are mountain dwarves. Hill dwarves hail from the south. Just an FYI if lore matters to you.
As for HP, I apologize for not being clear, level 1 is Max hp.
