Lower the difficulty if you cannot handle it?

I killed the spider swarms in the 1.0.langhotfix yesterday with acid-magic and Amiri was tanking them with 2-3 health potions, the others were unconscious.

This is done over and over again.

Something is too tough -> it is a bug on "unfair" difficulty
Too less fps -> it is a bug on "extreme" graphics settings

What happens -> unfair difficulty disappears and becomes the new standard, beautiful graphics disappear und standard becomes the new extreme graphics

It appears, if you kill the big spiders with Acid, there are not even spider swarms. There may be other tricks and tips, which we never learn if people file bug reports like this.

p.s. I play custom difficulty with "normal" enemies, "1.0" damage to party, but weaker enemies and my companions can go unconscious before they die permanent. This is very nice to play, there are the odd super-hits of enemies.

I either read or heard via a lets play video that some of the early fights are bugged in anything but normal mode. Difficulty simply stacks stats onto creatures, so some of the tougher creatures can't be hit even on a roll of 20 in higher difficulties.

Looking back at some of the older lets plays of beta games, there used to be three large spiders in the cave. So it sounds like someone dumped a tougher group into the cave and then failed to test it.

In addition to the spiders I ran into an unwinable fight at the temple vs. the bear/treant creature. Nothing I could do could cause any real damage before a wipe. So it looks like balance issues are going to be a real problem with this title.

I was wondering about the system anyway.
My character has combined 17 RK (Armor) for melee attacks and my Attack is +5 in melee.
I assume the enemies have similar stats (I disabled all information about enemies in my game).

This means on a D20, I need to roll above 12 to cause any damage to those enemies. This is tough, but I remember this from DSA (especially BG1) where people rolled intelligent melee fighters and couldn't hit anything :D
And if I understood those rules correctly.

Look at my class "Schwertheiliger". With level 20, I can add GAB (GrundAngriffsBonus) 20 to all my melee attacks. I don't dare to cross-class, just because of this feature.

I'll need to look up some official Pathfinder class builds, love this and spent 2h 45min just on my character creation in the first place.

I wonder about the same:
my tank has an RS of 30 and still, a lot of stronger enemies do kill him like nothing. I have a list of enemies, i avoid until i have leveled up a bit, like "Lonly Skeleton", "Magic Lion", "Dragon"....
And its not only him, the next RS are 28, 25, 22... I think, the lowest has 15 or so. And still, i lose against higher rank enemies.

I also wonder, if the group carries too much weight, do they perform worse in combat?
Wouldn't it be better to count weight individually, rather than affect all party members?

My acid is actual a touching attack and RK does not apply here. This may be a good weapon against those swarms.

It is also advisable to surround enemies. My class has an opportunity to hit anyone around him who tries to use a spell :P

... But they DO count the weight individually?
When you check them, everybody has his/her own weight line. And they can have too much weight. In this case there is a big red dot on the character screen. In this case i had to remove weight, like an armour or something like this.

But doesn´t matter for me now: i hit an game breaking bug. After searching some time for a solution, my last try is to reinstall the game and hope for the best. Otherwise i have to wait for the patches. And with this amount of bugs going around at the moment i have the strange feeling, that this can need months...
Nice reward for playing early.

This is normal with new releases.
I didn't buy Original Sin 2, because the first part was so buggy at release, I couldn't play on after ~15 restarts of the character.

Spellforce 3 was very buggy and had a bad German translation compared to this (They did have German voice over where applicable, though).

If they count weight individually, how?
How do I put all the armors onto my dwarf and give all light spells to by undead Inquisitor?

This are different questions.
1: Look at the character screen (pressing C in the game): you see the picture and below is this weight line. I cannot check it at the moment, as the game is reeinstalled. If your character is too tired, it can happen, that you have gave this character too much weight and then you have to remove some stuff.

2. You cannot give everybody everything. Some classes for example cannot wear armour. Or cannot use scrolls. My fighter for example cannot use scrolls. In this case this articles are marked red. Sometimes you can learn it, like taking the "wear medium armour"-ability when leveling up. Sometimes its completly forbidden for your class.

See attached. You can't. Individual characters can only carry what their class allows them to, ie. what they can equip.

I meant the right hand side on your screenshot. If the whole group carries too much weight, they move slower for example. Do they also get a malus in combat?

yes. You can check it for yourself:

equip somebody with stuff, which is waaaay to heavy for him. Then move the mouse over the weight line. And it tells you, that you get a lot of minus. It already begins at medium weight and gets more and more malus as more as they carry. They have less protection and gets tired much earlier.

They get whatever penalty is imposed by reduced speed, such as would occur in a swamp.

Has anyone got tips on beating the spider spanws on challenging difficulty? Worse enemy so far.

If you started with a mage type character, kill it with fire. Burning hands, burning hands, and burning hands all day every day.

If you have 2000 gold lying around, buy a mage type character and kill it with fire.

If you have an evil cleric, I believe channel negative energy works swimmingly (be watchful of friendly fire)

Your clerics can buy you some turns if you reached level 3 and chain cast lesser restoration. (maybe interwined with some channel positive energy when your characters' hp pool gets too low)

As far as I know, Torches, alchemist fire and acid flasks are a trap when dealing with these things.

Edit: Also, if you are level 3, Molten Orb is a terrible spell that doesn't scale, but it one-shots those damn things, even more if they're swarming the bait character you sent to them.

The balance on this game is all over the place. Going to wait until a few more patchesa re released.
