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

got steadfast determination on last levelup.

However Umber hulks confusion was vs mind (will) save
and also the carrion crawler paralyse was vs. will save.

(in the log it used the much lower will value and not the fort. value with the save roll.)

steadfast doesnt change saves it changes the stat you use for will, instead of wisdom you use con

(yes, i know how it worked all the years)
but the numbers in the log matched my wis score.

ok, thats a bit easier to understand

tho screen shot would help

tried on my dwarf, will save 22 with steadfast, rolled a base 24 will against a tiger's howl (+2 racial vs spells)

so not sure what issue you are having without seeing a screenie

After some more testing, it turns out it works well !
And i did not know how it worked

@Blackman thxs & sorry for the bother.

All the years i wrongly assumed, it would use fort.saves instead of will saves,
but it's only the Con. modifier instead of Wis. modifier.

I'll leave this here, but lock it down. Its good information that could help others if they search the feat.
