+Avoid the Lugal area when you don't have to go there due to a quest. It's the only area you can't just walk back out but will have to fight all the mercs first.
+Apart from the Invitations quest, you always risk a fight when you exit a Dingirra family area. Save and reload if you really want to avoid these.
+The Master of the Pits will be after your money on two days: On the day you go adventuring with Krimm the first time and on the last day you get off to buy weapons just before the Liberty Challenge. Blow all your money (or almost all) before entering the arena on those two days to get the related achievement.
+After returning back to the arena on your first Dingirra adv. day with Krimm, you'll face a quest with 0 to many arena slave fights before a Boss. You can try your luck or use saving and reloading. I managed to clear this out with only two slave fights by just reloading a save when I saw the two guys in the cell (they always attack and have no info for you)
+ On Riley's Quest there are 7 guard fights and 1 Boss. You'll get a level-up after 3 fights. There's no shortcut here except trying the stunts (and reloading after failed stunts if you really don't want to fight). You can always lose a fight, but you'll then fail the quest.
Available quest shortcuts:
Family slave day --- Kiduu-quest
Other family quests might be shorter than this, but I like the Kiduu-reward the most. ( Family-quest rewards are listed in here: Legendary Usables - Quick Reference
)You can cut some corners in the dungeon, but you'll lose some exploring fun this way...anyway "short" route:
These tunnels can be cleared by just using the steam-path shortcuts twice and then fighting the Boss (easy), but you'll miss a bit of dialogue. Best for immersion would be to
