Rough Guide/Walkthrough here
This is going for Ending 1 where you just need to complete just about everything.
Starting Ability:
Combat Experience: Straight to Level 3 (Not that useful since there undead which you can grind infinitely.
Lucky: Give +2 luck (Useful for the final boss fight, otherwise other luck-roll can just save reload)
Talented: Unlock Special Event (Useless since from what i can see it only unlock an alternate ending route)
Spoil of Wars: Give a better starter weapon, Bag of Holding and 3 Potion (2d6 + 3 weapon, this can pretty much last you till you get the Boss-event Weapon)
For me, i picked Spoil of Wars and Lucky.
For first trait, go for Combat Training since you will be fighting a lot.
Tips:
Save often, especially before any fight.
'A' key to open up shortcut and you would want to always enter battle with Conceal mode
Pick up any shiny you see, i will only specify Event Item in the guide.
Always use Thief Garment (Light) for the extra 10% Evasion
Evasion will be your best friend here for 80% of the fights (Most of the early fight can be easily dodged)
Beach:
Linear, nothing to say other than the Introduction Event at 2nd area, will consume your first Hairpin [Pin]
*Don't worry about saving Pin since you can grind money and buy it infinitely or pick Lockpicking Ace Traits
Pick up Shell which will be used for Crafting and Oil for certain event.
Entrance:
Linear, just pickup the Wax at the Crate (Used for Crafting)
Just go to next area, do not need to stealth since the Mob will look away.
Cavern B2:
Ship:
**At this point you can clear the game for Ending 5 and some Achievement, either via the Small Boat inside the Hatch room of the ship, or Raft at the Bottom room of Cavern B2 if you have 5 Lumbers and 'Talented' ability from the Start
**Any trait points you earn just put it into the Assassination Tree
Underworld:
Temple:
Ending:
