[RPG] Does expeditious retreat affect warlock fly speed

dnd-3.5espellswarlock

Expeditious Retreat says

This spell increases your base land speed by 30 feet. (This adjustment is treated as an enhancement bonus.) There is no effect on other modes of movement, such as burrow, climb, fly, or swim.

The fell flight invocation states that the fly speed is your land speed.

FELL FLIGHT
Lesser; 3rd
When you use this invocation, the
powers of darkness bear you aloft as
you sprout a streaming, winglike cape
of shadows. You can fl y at a speed equal
to your land speed with good maneuverability
for 24 hours.

Does Expeditious Retreat affect the warlocks fell flight invocation? Would the order matter, for example, should the land speed be increased first and then fell flight be invoked?

Best Answer

I would say no. First of all, expeditious retreat specifies it doesn't affect flying, and secondly, it only lasts 1 minute/level while the invocation lasts all the time. But, it wouldn't be out of line to rule that it does work.
