2 questions.
Is there an in game wiki? Information seems way spread out over the webz.
Are status effects always blocked if the respective shield is up? Do they always go through if said shield is down or is there some saving bonus roll/penetration for each scenario?
No ingame wiki.
Divinity Original Sin 2 Wiki | Divinity Original Sin 2 Wiki seemed fairly updated, at least skills and such, but didn't check it out much, if you want to test stuff you can just fire the Gamemaster mode, spawn a troll with lots of Con for high hp, then spawn another char and give it whatever skills/gear you want and hit the troll.
Yes effects are always blocked, although some stuff goes through directly because they're not considered blockable effect(notably you can teleport fuckers around even with their full magic armor). They will always apply when shield is down unless there's a random aspect to it, but it seems they removed that part from D:OS1 where if you had too low int it would give you less than 100% chance to apply effects, I believe everything in the game is 100%.
Mind you, some of the CC is also 2 parts. For example if you want to freeze, you have to chill first, then freeze. Multiple applications in one spell will work(like the 3 little icicle spells you can start with, if they overlap you'll freeze in one spell). Similarily if you want to stun, you have to shock first. Exception to both is if the target is Wet(rain), they will instantly go to Stun/Freeze when you hit them with the appropriate attack. This works also in reverse for Burning, if you're Wet you'll go to Warm instead of Burning right away(generally since you're standing in fire you'll still burn after though).
Also most/all abilities will inflict their damage first THEN roll for armor. If an enemy has 1 physical armor left and you hit them with Bull's Rush, it'll do like 10dmg first, removing the armor, then apply knockdown which works because the enemy has no more armor.
Quick question, i just went through the hide out where the underground prison is in the fort and came up into some high priest doing some shit with a silent monk. Went into the fight at lvl 3 and there is 6 of them and seems abit challenging (gear isn't very good atm). Is this doable or supposed to be like the end of the fort or?
One other quickie, i had a chick take my main guys coller off and then got thrown in prison just on that charcter. It says find a way out but i can't fucking see h ow and there is no health on the door to break down? Tried running a rogue down to open from other side but nada
For that fight you probably want to clear more stuff, it's one of the last fight before you escape(you can actually escape without doing that fight too). The 3 golems are in cages so they take several turns getting out, but you have to handle the boss+3casters so yeah it's rough at lvl 3, although not impossible I would guess.
For the prison I'm honestly not sure, I got caught too and wasn't entirely sure how to get out. What I THINK you're supposed to do is use the Teleport scroll you can loot in there with a character that's standing outside on your char inside, and get them out through the hole in the wall. I haven't tried as it sounds like a pain in the dick, I just reloaded and avoided the magister. You get a prison key in that area too but it seemingly disappeared when I got thrown in there even though it was on another char. Maybe they reset the key to where it was on the ground at first I didn't go check.
