Doesn't stack with armor. Useful as a much cheaper alternative to +1 explorer's clothing from level 1-10, sell it when you want to buy +2 armor Heightens at even levels.

If you are trying to be quiet and stay out of sight, you might want to consider not having your stealthy mission be foiled by the local guard dogs (or other monsters with scent).

With Treat Wounds being a thing, this is only to speed up healing in a pinch. This becomes much more efficient at higher levels, as you can use it to conserve 10 minute buffs. Note that you can't do the 3 action version. Heightens.

Shorter duration than see invisibility and you need to catch the enemies in the initial burst, meaning you also can't pre-buff yourself. But it does help out the rest of your group (and see invisibility isn't on the primal list).

Scouting can be pretty niche in some campaigns, and most familiar owners can get it from their spell list. So a bit situational yet still good in the right circumstances.

Gaining a fly speed to chase down flying enemies or traverse terrain is common enough to want a wand (or two) for. The Heightened 7th has an hour duration. For that price you can buy rouhgly 9 of this level. You will end up with 15 minutes less but you can divide the duration. For 250gp more (950gp total) you can get it as a cloak for 10 minutes though, somewhat lessening the value.

The duration goes down when hit, and only works on physical damage. So Blink might be better in most cases. Though you have more leeway when casting this before a fight. Heightens at even levels.

Walk on air to chase down flying enemies or traverse terrain is common enough to want a wand (or two) for. Only not a 5 because Fly Heightened 7th has an hour duration.

A bit step up from the lower level version since you only need one for the party. The impact is still relatively low since it is very situational It is usually just an added layer to prevent baddies from finding you (like stuff to prevent people from scrying on you etc).

Death effects can be devastating, if you find out during a fight a tough creature has them you might not have the luxury of waiting for your party member to cast this on you. Also protects against negative effects and damage, as well as suppressing Doomed.

Gaining a fly speed to chase down flying enemies or traverse terrain is common enough to want a wand (or two) for. Consider buying multiple 4th level Fly wands if you want to divide the duration better. Or saving up for a greater cloak of the bat or winged armor property rune for unlimited flight.

No matter their senses you remain undetected. So a big step up from being invisible. And with stuff like True Seeing being a 6th level base (non-heightened) they need to critical succeed on the counteract check.
