The way that spellcasters fail after taking damage has been externalized to this file.

In BG2EE we have:

2DA V1.0
BEHAVIOR             VALUE
CHECK_MODE           0

Known values for CHECK_MODE are:
Bug: CHECK_MODE values greater than or equal to 1 are bugged (since all those inequality symbols should be < instead of >).
As a result, you might want to stick with the default behavior (CHECK_MODE=0) until this bug is fixed.
  • Constitution and Luck use their aggregate/current scores, not necessarily the base values.
  • Unlike other dice affected by Luck, this one does not cap it at its normal min/max values.
    • +/−50 Luck is +/−50 to the roll.
