I made this save for what I consider to be the ideal start. Objective #1 was to stay at level 2 with minimal interaction with the world and collect all possible Elex Potions (EP) and Stat Potions, as well as map pieces, gems, and recipes for potions, food, and ammunition. Objective #2 was to obtain the "Stat" ability (+1 point per level) specifically at level 2. When I was planning this save, it turned out that only by collecting ALL the medium EP, Intelligence, and Cunning potions could I obtain this ability at level 2.

Drank 5 each of Marksmanship, Intelligence, and Cunning potions. 5 SEZ and 4 BEZ.

Learned 3 flight abilities (without them, you can't reach some areas), Level 2 Lockpicking, and Level 1 Break (also a necessity).

Failed to pick up 1 Intelligence potion (marked on the map with a chest). There were bandits to kill there; there was no other way. I also got four more potions just from quests (Attila got two warrior potions for the arena, Gosta got one yellow potion, and Martin, already in the fort, got one intellect potion.)

All companions and characters for quests outside of towns are marked on the map. All trolls, cyclops, and behemoths, as well as some elex veins (the map doesn't allow more marks. I left two marks in reserve.)

I practically didn't collect any loot. I killed three small creatures.
