How would I define this with the 4E ruleset?

[adminwheel3]

This is an always-on background bonus one of my players has. Was thinking it might be something I can keep running with the new ruleset?

Gain +1 to saving throws to end effects which Daze, Stun, Immobilize and Restrain you.

I just found in the support forum that effect-specific saving throw modifiers are not supported.

I must not have searched well enough.

Thanks!
