Greater thunder stomp and true strike

[Delvaron]

Would true strike bonus work on every target in the area of effect of greater thunderstomp?

As such caster uses True strike round one,
Then cast greater thunder stomp does said caster roll caster level plus casting stat plus 20 to all targets in a 60 foot line to determine if they are tripped?

The only thing stopping you would be a GM ruling to the contrary. The wording for the rules about how the spell works, how attack rolls work and how tripping and combat maneuvers (in general) work, present nothing that would inhibit that.

I would recommend this as a "quickened true strike" + "greater thunderstomp" combo. Otherwise, anyone who spellcrafts to see what you cast on round 1 is going to paint a giant target on your back between then and round 2.
