A lot of the work with magic house rules involve the skill Spellcraft. Some of the uses are from way back in 2013 and have not been revised, so beware. See the magic article for more information.

Ability Modifier

The skill Spellcraft is now used with either INT, WIS or CHA instead of INT only. Use whichever is the highest.

Residue

Not revised

It's also possible to attempt identifying a spell being cast from its residue alone (see table).

New skill check rules

Some rolls are now easier and others are harder (see table). Primarily, the main difference is that a "natural 1" is an automatic fail and a "natural 2" counts as -10 to the roll (with some exceptions).
