Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

So we went in the place today. Gullykin Crypt - 2 Paladins immune to disease. No failing saves on 1s cause of Steadfast Determination. 32+ fort. Save vs poison fort ~DC 20 successful. Still got the debuf and reduced con from undead.
Also the checks there probably take from non-existing skill ID-s cause with 30 in atletics and acrobatics we were landing on our asses at each climb and rope spot.

As a side-note I feel jump DC-s are set too high. You're basically only not failing jumps 90% of the time on level 25+. Level 10 can jump too you know. I'd love there to be some middle ground cause right now epics are jumping like crazy and anything below 25 level essentially can't jump through a medium bush.

Opinions?

Do you have the combat log / message available for review?
Were you wearing shields, armor with dex limits?

I can go there tomorrow and check. I had heavy entropium optimized and heavy shield for -4 penalty total which still should be 25 athletics/acrobatics. Surely enough for CR 15 area. Had to remove the shield anyway on most checks (rope) and emote after check still says i fell on my ass.

About poison saves. Don't have screenshot but am 100% sure I've seen DC around 20 for poison that on successful save still appplied debuff to Paladin with 30+ fort and steadfast.
