It seems unfair.* As per cleric spell of same name. Because the wizard version of the spell is a different spell level, the wizard receives a -2 penalty to spell checks
when casting it. For example, binding is a level 2 cleric spell but a level 3 wizard spell; therefore, when rolling on the spell table, the wizard applies
a -2 penalty to spell checks. On a result of natural 1, the wizard suffers a 50% chance of major corruption or misfire, rolling on the generic tables
as appropriate.
Wizard:
Level 1: Detect magic* 260
Level 2: Detect evil* 259
Level 3: Paralysis* 264
Level 3: Binding* 270
Cleric:
Level 1: Detect magic 260
Level 1: Detect evil 259
Level 1: Paralysis 264
Level 2: Binding 270
then because:
The modifiers for the wizard's versions of those spells should be:In general,
your spell succeeds if your spell check is equal to or
higher than a base DC of 10 + (2x spell level)
Level 1: Detect magic* = No modifier
Level 2: Detect evil* = -2
Level 3: Paralysis* = -4
Level 3: Binding* = -2
