Spiderweb Tangletraps - Unsure if Bug

[StoneFolk]

Neither immunity Web (probided by Ranger FE: Vermin) or Immunity: Entangle (provided by boots) lends protection from the spiderweb tangle traps in the spider tunnels - only to the spells themselves if cast.

This probably isn't a bug but I figured I should report it anyway because I was excited by the prospect of being able to run past the spiders cause screw those guys.

Not even sure immunity:web works against the spell web 100% of the time.  I believe it's an engine bug.

Not even sure immunity:web works against the spell web 100% of the time.  I believe it's an engine bug.

Specifically. Web Immunity does not work against the web spell (when casted) after the initial round.

This is however not an engine bug. This is a consequence of another feature that efu customly added.

In efu, conjuration spells decrease in DC every round, and expire when the dc hits 0, rather than that web, grease and other floor based conjuration spells expire based on the usual nwn time limit.

As a consequence, web, grease or other spells don't classify as Web (and others) for spell immunity after the first round. Because you are making dcs against a custom efu script. Not an actual web spell. (To clarify, if you have the item feats: Immunity: web in a normal nwn campaign, and an ettercap casts web on you; You are immune every round.)

The spell immunity: web also does not grant immunity against Web bolts (The monster ability) and web bolt traps. However, the druid feat Woodland stride and freedom of movement do provide immunity to all of the above.

There is nothing to fix here. Unless the DMs are inclined to look at their own conjuration script.

Possibly could, possibly may not. Very low in the list anyway. Though those traps and what not, are not such things that even should have immunity. Very much intentional as they are effects of different nature.
