Instead of swapping Garlic away for something else, I'd prefer if Garlic was made more useful yes.
For instance, having Garlic equipped could negate the "night" effect on enemies. Like, night makes them stronger, Garlic makes you just as much stronger during the night, negating the boost they get. It'd be a way to translate Garlic's "warding off evil" qualities.
Or, maybe throwing Garlic makes enemies avoid getting close to you; Dunno. These are just examples of what I mean. Ultimatelly, I'd much prefer improvements on Garlic than swapping it for something else.
