House Rules:
 
-Summons are capped at 1. You can have 1 dedicated "pet." You can have
 
more, but they can't be adventuring. Stash them at home.
-For the purposes of the campaign, you can have any non-magical item in any
 
quantity. You guys are experienced/powerful enough to have access to stuff.
-We'll now be keeping track of time and expenses.
-Since you're horsies, you travel overland at a Fast pace, with no passive
 
penalty.
-You don't have to pay for the upkeep of your Noble Estate in
 
Stratofortress.
-For the flyers, if you take Heavy/Medium Armor Master, you can now fly at
 
a speed of 40 while wearing it.
-For those that want to play a Dragon or Minotaur (please don't), you can
 
take a feat: Racial Paragon: +1 to either stat that is modified by your
 
race, capped at 20; you get the secondary ability of the race; you get
 
advantage on interacting with non-paragons of the same race
 
Crafting:
 
Item formulae can be bought and sold. Common is 50 gp, Uncommon is 500 gp,
 
Rare is 7500, Very Rare is 25,000 and will require special components,
 
Legendary is on a case-by-case basis.
Crafting is now 50 gp/day.
You can also research item formulae, with a target based on DC. DC 10 gives
 
you 50gp, DC 15 gives you 100, DC 20 gives you 250, DC 25 gives you 500, DC
 
30+ gives you 1000. Researching an item formula is more costly than regular
 
research, costing you 25 gp/attempt. Can't do more than 1 formula at a
 
time.
 
Magic Items:
They're a bit more common. You get: 1 very rare, 2 rares, 2 uncommon OR 1
 
legendary, 1 rare, 1 uncommon.
