Thosha Here's my list.
The player accumulates a lot of equipment that very quickly becomes obsolete by finding better items. This includes:
All iron weapons once you get steel replacements,
All iron armor, shields not actually on any character,
All regular health potions,
All antidotes,
All goos,
All revival potions,
All serums.
All steel armor, shields and weapons after the end of 3rd Arclent War.
So sell everything on this list.
Some items improve greatly the combat effectiveness of characters.
The following items can be considered highly useful.
Yarra, buttplug (Stineford 1st visit)
Qum, dildo (lust preservation), handcuffs (stunning)
Robin
- Freezing staff (magic shop Stineford after buying the business)
- Master Staff (Aka's Route) then give Freezing staff to Altina
Nalili, buttplug ASAP
Riala, buttplug ASAP
Hilstara, steel shield (Stineford 1st visit, helps enormously with spider fights)
Simon, 1 durge sword (so much better and more reliable than axes).
Varia, 1 durge sword.
I have not found any protective gear to be particularly necessary.
Except for the steel shield for Hilstara, all of the items you find in various locations are useful at least to the current state of the game
But the buttplugs are a must.
