My D&D Realm of Whatever - Whisper Gnomes

I'm going to start this blog off with a simple subrace: the whisper gnome. The gnome's silent cousin from Races of Stone (3.5).

Whisper Gnome

In addition to the abilities of gnomes, a whisper gnome has these traits.
Ability Score Increase. Your Dexterity Score increases by 1. 
Swift Movement. You are faster than other gnomes. Your base walking speed is 30 feet. 

Sneaky. You have proficiency in the Stealth skill. 

Magic of Silence. You can cast the silence spell, centered on yourself, once with this trait. You regain the ability to cast it this way when you finish a short or long rest. Intelligence is your spellcasting ability for this spell.

With Magic of Silence, I was torn between having the whisper gnome recharge it after any rest or just a long rest.  I went with the short and long rest, since the eladrin from the DMG had the spell misty step (2nd-level spell) with a recharge of short or long rest, and the spell silence, on top of being another 2nd-level spell, is a ritual, too. The "target self" limitation weakens the worst abuses of it.

On the other hand, I do add a couple of more small traits, and the eladrin trades the high elf's cantrip and extra language for misty step, while my whisper gnome gains speed and stealth.

On the other hand (ARGUMENT-SHIVA!) I could back it off to "one use per long rest," and add a feat to increase it to "once use per any rest."

An interesting feat from the Races of Stone (3.5) to add.

Silencing Strike

Prerequisite: Whisper Gnome

When you attack an enemy within 30 feet of you and you have advantage on the attack roll, if you hit, you can use your Magic of Silence ability, but instead of centering silence on yourself, you can center it on your target. You can still only use Magic of Silence once, and regain the use after a short or long rest.
