Antimagic field and spellbane

[DMoogle]

If player A has a spellbane, set to spellbane, and also has antimagic field up, suppressing the spellbane, and player B has spellbane, set to antimagic field. What is the best way to deal with this interaction?

I'd vote for throwing a book at them. Preferably something heavy

I'd borrow from this portion of the spell Spell Turning altering the table to fit the situation i.e. the results of rolls of 80+ are fine, the others need some adapting. Stops a little shy of throwing the book at them which I suspect a lot of DMs would want to do at that point, not just Val'bryn.

d% Effect
01–70 Spell drains away without effect.
71–80 Spell affects both of you equally at full effect.
81–97 Both turning effects are rendered nonfunctional for 1d4 minutes.
98–100 Both of you go through a rift into another plane.

Maybe something like this:

01-65 Antimagic effects overlap, spellbane has no effect
66-85 Both effect are non-functional, Magic works otherwise normally in the area for 1d4 minutes
86-95 Dead magic area created in 50 to 500 ft radius.
96-100 Casters and anyone else within 100ft drawn through a rift to a plane of Wild Magic.

PS The players should need to investigate to discover the areas effected by Dead or Wild magic, don't just tell them the results.

Personally my answer is, "It's called Aroden's Spellbane, and you don't know it."

Mostly because the wording of that spell has more holes in it than Swiss cheese and can cause more problems than the death of Archduke Ferdinand.
