This spell should be added as a means to make a Will Save with a Concentration Check! First time I'm seeing it, and while it's linked in "Free D&D", it's not mentioned anywhere else!

Steely FocusTransmutation

Components: V, S
Casting Time: 1 action
Range: Touch
Target: One creature touched
Duration: 1 hour/level
Saving Throw: Will negates (harmless)
Spell Resistance: Yes
Steely focus allows its target to resist magical distractions more easily. In place of a Will saving throw to resist the effects of a distracting spell (one that causes the target to lose actions) such as Tasha's hideous laughter or daze, the target of this spell can substitute a Concentration check. Further, the spell grants a +4 bonus on Concentration checks, and this bonus stacks with all other bonuses. Against mundane distractions requiring a Concentration check, this spell grants only the +4 bonus.[/spoiler]
