You and your dwarves.
Well, first the height and weight are out of bounds for a female dwarf. You should probably fix that to realistic.
Where did you put the +1 to ability scores at 4th level? I left it blank on the sheet.
Brew potion might or might not be worth it. Traditionally, we have discouraged crafting in general and there has not been opportunity for it except between adventures.
There is another consideration on your gear. Tasha is holding a magic item as community property that she doesn't use. It is a +1 Shock Mace that would be perfect for Olbryn. I recommend having your morningstar be Mwk with Silver Tips instead so you can cover lyncanthropes.
Also, I suggest better armor since she will not be slowed down by it. Also you need to invest in a mount so you can keep up with the party. They have made a point to all be mounted and it will save IC discussion and ease integration if you are already prepared for it.
Btw, apparently I cannot read. 10000 XP means 5th level, not 4th. Go ahead and level up.
