Mounted Immediate Actions

[Calypsopoxta]

So I'm looking for good feats to use while mounted and I've run across these 3 that confuse me a little.

Mounted Combat: Once per round you can make a ride check(as an immediate action) when your mount is struck in combat. If your check is higher than the attack roll, the attack is negated.

Trick riding: Among other bonuses, you can make a second ride check per round to negate an attack on your mount.

Indomitable Mount: Once per round you can make a ride check(as an immediate action) instead of a saving throw for your mount.

So you might have guessed by now, but, I'm not sure how to interpret an extra Immediate Action per round. Should I just consider the wording "you can use one extra Immediate Action per round if it is to negate an attack on your mount with a ride check"?

Even then, I'm not sure what my options are during a round.

Can I make a ride check to make a save for my mount, then if it is hit, make a ride check in the same round afterwards?

Mounted Combat & Trick Riding: If your mount is hit in combat, you can spend an immediate action to make a Ride check to negate that attack. If your mount is hit in combat a second time, you can make a second Ride check to negate the second attack. No immediate action is necessary for the second Ride check, but you must have spent an immediate action to make the first Ride check.

Indomitable Mount: If your mount is subject to an effect that allows a saving throw, you can attempt a Ride check as an immediate action in place of the mount's saving throw.

You can never do both in the same round, since the first Ride check consumes your immediate action.

It doesn't quite word it that way though. Trick Riding simply declares "You can make a check using Mounted Combat(referencing use of the feat) to negate a hit on your mount twice per round instead of just once."

That says @Tom Baumbach.

If you spend an immediate action for negate an attack on your mount, you can negate a second one at "no cost" (in term of immediate action).

But if you use an immediate action for that, you have no more immediate action for doing another thing LIKE Indomitable Mount.

You must choose in that case between negate one (or two with Trick Riding) attack or replace the ST of your mount.
