Some people including myself love to use guides/wikis while playing games.
Depends what for you’re using it. If you use it to see items etc, go to Grimtools instead. For secret quests go to Grimdawn.com and for quests in general just play the game, because everything is so straight forward that it’s impossible to miss anything.
I actually think that the best GD wiki is grimtools, because it’s always up-to-date and has even stat range in there (e.g. 36 - 54% conversion), if we talk about items, skills, devotions etc.
Detailed pet stats are only available in the wiki. And that is way out of date.
Do you mean something like this?
I could not find any detailed info about any pet in a wiki, maybe I just searched wrongly.
I mean like this: https://grimdawn.gamepedia.com/Summon_Familiar_(Skill)
The base stats and resistances aren’t displayed anywhere else afaik.
I mainly mean like quests, shrines, one shot chests, details on all the areas like if it contains a secret or not like breakable walls, hidden remains ect.
Tbh, the only mastery pet that doesn’t have that is Blight Fiend, I don’t count skeletons because they’re basically trash that deals damage only (trash because they die fast no matter what). I do agree it’s quite handy, but on the other hand, it’s not because you’ll take resists anyway for a pet build (for the pet I mean) and attributes don’t really matter at this point, because you’ll get % damage anyway.
Dammitt wanted to add pets on GT at some point, right? I don’t know what happened to that.

This will help for the whole map.

And this for shrines and one-shot chests.
Well, Zantai has plans to nerf the Familiar’s resistances because apparently they are too much. Also, knowing pet DA/OA helps alot if you want to min/max.
Also, yeah. He did say he might add them at some point. No idea what when or if it will happen.
We gotta torture Dammitt to add it, then.
