Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Cancelling persistent environmental effects

I'm having some issues with persistent environmental effects such as Hiberheim's Chill and the spider desert's Slow.
I would have expected that drinking Milk & honey (sets Warm) or casting a Haste would cancel the effect for the duration of the spell/food bonus.
It doesn't though. It works immediately and then the next round the environmental effect reasserts itself.
I can see how this is the result of the code, but is it the intended behaviour?

Both effects seem to be intended.

That said I had the repeated experience of immunities to the sandstorm effect on different characters. The only one logical was the immunity for the level 5 geomancer with the related talent. Else I can only guess by observation - it seemed those characters are immune that reach a level 5 skill.

But that could be a mere correlation, may be other effects are in place (like exceeding a treshold for stat points e.g.). Would be nice if someone knwledgeable could shed light on the Luculla desert effects.
