raditz: Haste, stoneskin, weakness last all 3 rounds but I believe won't stack. Not 100% sure about haste even working I see very little difference when I use it.

Elemental protection spells work all 3 but also do stack. So 2 50% in the first 2 rounds will make you immune in the third.

retromarthmus: Okay my knowledge Is a bit rusty
I'm sure the spells like stone skin and weakness last all three, it might say in the spell discription.
Also the "air prot." And stuff spells only work against Air spells, not against the bows, axes, swords, melee - that'd be normal defence.

sparakosa: Hi.
Spells miss description.
How long do the spell effect work?
If I cast stoneskin or weaknes does effect work during all 3 hits, only first one, or during combat?
Please, answer.
Also, does weakness effects damage from all weapons like crossbows and bows?
Thanks!
