What's Missing?: Destiny version

Noticed that the "Unseen" destiny appears to have a minor flaw in its lvl7 ability:

Level 7- The Unheard
Even on your worst day, no one can catch you. Whenever you roll a natural 1 on a stealth check, treat it as if you had rolled a natural 20 instead. In addition, you may use the following utility talent:

Cover of Night - 1/Day
For the next 10 minutes, up to 6 allies may use your stealth modifier when making stealth checks instead of their own.

Cover of Night heavily relies on a character being min-maxed in stealth. If your allies can beat or match you in it (precision is a commonly used attribute, whether as a focus or "spare points dump"), it becomes rather useless, and can have a negligible in effect unless you go out of your way to put everything into stealth (18-20 value), which in itself is a pretty big investment for what you're supposed to be receiving.  

Since stealth is a skill you are generally unable to change after you make your character, and destinies are picked at lvl4 (a lot of real-life time from lvl1), it makes most characters that want to be stealthy via the destiny forced to do it from level 1, or they lose some of their benefits from indecisiveness. An athletic/knowledgable/sense-focused character that wants the destiny to make stealth possible for them (due to low-average stealth values and limitation of attribute points, the only alternatives would be "stealth mode" or disguises) to lose out on a normally viable destiny option.

I think it should have an extra, alternate ability option to pick from, or a change to have it not rely on the stealth skill. All the other destinies can function fairly fine for most character "templates", whether through massive boosts, unreliance on any specific skill/attribute, or no-rolls functionality.

So here are two ideas to add as alternate abilities for the lvl7 Unseen destiny, as well as a slight rework of the current one:

Essence of Void:

With cat-like tread:

Cover of Night -Rework:

All of the win for the Pirates of Penzance reference.

I think alternates would be the main way to go about it since Cover of Night would still be quite useful for those with the high stealth score. It feels really odd for them to use skills outside of stealth for that Destiny's purpose. I like With Cat-like Tread for it's simplicity. Your own description of Essence of Void has multiple sidebar notes.

I think tweaking the level 7 slightly so you choose between Cover of Darkness and With Cat-like Tread would work well. I'm all for having choices in the level 7 part of a destiny, and WCT is a nice, concise, and incredibly useful ability.

Hm, would it be too much if we added "other creatures cannot hear you if you do not will it" to cat-like-tread?

Or make something akin to a "muffle" ability, to do loud things in a quiet fashion?

Hm, this could work as it's own ability as well, possibly separate from 'audiomancy' - an area 'silence' effect...
