1. 4 member party size max (no sending anyone to camp to switch in or out) sometimes I play with only 3
2. Can only use class appropriate scrolls
3. no throwing potions
4. Max 2 healing potions equipped by character
5. Max 2 "grenade type" item per character
6. don't collect food items I use supply packs only
7. no buffing prior to combat being initiated
8. no bribing merchants (no need as there is so much gold)
9. Long rest when it seems like a full day may have passed
10. 1 or two weapons max carried by each party member (ie my fighter carries only 1 mele and 1 ranged weapon)
11. I always hire Ogres but never call on them (I'm just bribing them to abandon the Goblins)
12. After rescuing Halsin I always go out the front door (lol its quite a fight)
13 Only time I use barrelmancy is the "smoke powder room" in the Goblin camp....I just can't resist!
14 RP characters in a sensible and logical fashion to try and stay in character so not all quests are always pursued.
15. Generally treat the map in a linear fashion that progresses from the Nautiloid wreck to the Goblin camp then underdark. All other locations are in between ( this takes some real imagination at times)
16. Often when I include Wyll (especially if Gale is in party) I have him masquerade as a Sorcerer to hide his Warlock status until it is no longer possible. This provides some real challenges (no Eldritch blast, no familiar no Warlock unique spells)
17 Sometimes play Shadowheart unarmored and use her as a pure healer/semi rogue. Is actually kind of fun.

many others that I can't think of right now
