Original heroes/characters questline path(s) quests related, places, and things not to miss (Eventually lore related).
Better guides about crafting, what is worth and what isn't, current farm guide is highly outdated. (Someone should probably write, about a guide about getting Thievery item, and using / abusing the mirror in L. Vengance, and robbing pretty much 100% of the NPC in the game, as there is no repercussion what so ever about it.) (Every single character can pickpocket anygiven characters once, if you manage to find 3 pieces of Thivery (which is super easy (Chest, Belt, Glove)) you can net a good 14kgolds / NPC which is by far the best usage of the time of anybody else. Unlike the current crafting guides.
Also writte simple guide about, Mixing of classes, what Main Class work well with other one. Aka. Aero/Hydro for example. (Needed are especially, Warfare good combos, and Rangers. Other should be logical more or less.)
Another most needed aspected, is tidious quests walkthough. Aka the Blood Path in Lucian Church for exemple. If rushed, it's very cryptic. A lot of quest can be hard to understand, use self judgement on that. (That was the only one who stopped me for a good 30 minutes)
Figure actuals % values of skills, or fix the current typo of skills deffinition of skills, so they display ?% instead of ??
From my experience, these number as easy to figure out as there are always rounder 10 15 30 33 etc.
Secrets / Spoiler section,
This one shouldn't be a focus, but should exist, so people can add to it as time past when they found amazing stuff in their oppinions.
Comprehensif, guide about Civil, and Combat skills. What's good, what's bad, why X why Y.
A must being Thivery, Persuasion, LoreMaster(Unless thievery abusing.) for any parties. (Outside of combat skills obviously)
For any lore freak, an timeline would be a blessing for peoples who care about it. Listed by years, and big and meaniful events.(Refered in game directly with main characters)
Exploit, and glitch
This section, in my oppinion should feature great mechanic usage as well but not only.
For exemple in coop, you can eat sources from bodies usable, as the same time to get 2 sources points from it. This is insanely easy to do.
Another "exploit", or cleaver use of mechanics, should explain that fleeing after killing an enemy doesn't respawn it for example.
Another being in coop again, you can buffer you character (that are not in the player party that engage RP/Talking with NPC)
It's a very simple process, If you aren't the one engaging RP, you can listen to it, that make your character "frozen" in term of turns, allowing you in some cases to buffer buff, 2 character in the non engaging party, and 1 in the engaging party. Giving you a great edge in a lot of fights. (Clear mind, hast, Magic shell, fortify(carefull with this one prevent tp))
Some exploit can be cornering a character, between 2 very high armor, and MArmor charcarter preventing him to move (But that cant be use in many cases)
Cursed VS Blessed especially how or what cleanse Necro Fire. (Blessing, Blesses consomable etc)
Necrofire is by fast the one the "hardest to convert, or getting rid of.
Artefacts guide, where to find each pieces, and what it gives you.
Also very relevent in my oppinion, to say vagually that if an artefact is related to a quest, do not sell it without saying explecittly where it's used, unless in spoil banner. (SwornBreaker for example)
For the madmans, Posting spot of hidden digging spot, with screenshot of the ingame place, and a map place.
Very important, Pyramids places, it's very usefull even in solo to have 2. Especially in DriftWoord, since it allow you to drop one near the source fontain near the Meistr to refill when needed, it also help solo player, to drop one down, and move his whole party whereever he need to. And teleport back when he's ready.
Glitch, and Knowned bugs, that you personally reported and know are reported.
For example i got a shield near the statue of the "GodKind" that "set deflect" except it doesn't.)
