Mounted Combat allows you to replace your mount’s AC with your Ride check once per round. But enemies rarely target my mount with attacks—my mount is far more likely to be caught in the area of an effect that requires a saving throw than she is to be attacked. Is there any feat that works like Mounted Combat, but for saving throws?
I know Pathfinder has one, Indomitable Mount, but since Pathfinder unconscionably nerfed Mounted Combat to use an immediate action, and Indomitable Mount inherits that (making the two feats mutually exclusive, despite one requiring the other), I am interested to see if a similar concept was ever published for 3.5e, which presumably would have retained Mounted Combat’s 1/round usage rather than immediate-action usage.
Official or licensed 3.5e material only, please. Otherwise, go nuts.
