Need a spell of 3rd level for contingency

[AnnoyingOrange]

I got an 11th level wizard (of the white circle), which has access to all wizard schools as well as abjuration school and subtype healing spells from the cleric spell list.
I need a 3rd level spell (or lower) to use with contingency, spells from spell compendium (3.5) might be allowed, any suggestions ?

I suppose it depends on the campaign you're playing in...

A couple of useful ones are:

1: Protection from energy if subjected to elemental damage
2: Water breathing if immersed in water for x amount of times
3: protection from evil / good / law / chaos or its 10' counterpart if ever charmed, dominated etc.

I am mostly concerned about potential combat, last spell I had 'hanging' was a vigor spell, essentially giving me fast healing 2 for a good while, activated by saying a trigger word. I just feel there have to be better options. Ablative Sphere is another spell I am considering.

My main concern was arrows, flyers, and rays, so I used Mirror Image set to "whenever I'm about to be attacked." At 12th level I switched it to Greater Invisibility.

Mirror image as Reynard suggests is a good 'avoid getting hit' spell
