Sonic Tank | Supersonic Tank

How about this?

Sonic Wave/Sonic Boom: fits more on the theme of destruction and has also the potential to be a buff. For example:
increase attack either constantly or exponentionally, do something divey on fellow creatures, accelerate once, do the SoFree trick and attack randomly for double attack just like you had momentum, etc. or make a loud noise to bleed your opponent's ears out to make them half-potent to attack, dealing only half damage (or 2 less).

Sonic Tank has now been changed. Gained a little unoriginality in the hope that it fits more Air's Theme.

Hmmm... could've sworn you'ld make a hover tank for ... but I do like this...
The potential for deadly Wyrms is interesting (assuming the dives would stack with the creature's own ability).

Actually, that brings a very important point up:
What happens if I hit the same creature with 2 of these?

Just imagine what a full 6 of these would do in conjunction with a flown vampire dagger...
4*2^6 = 256 vampiric damage!

Maybe a hover tank would have caused less trouble with balancing ^^" The original Sonic tank had a different ability that - in the audience's opinion - was not fitting air's theme. And now it's OP.
Yes, the ability would be stackable, enabling 1 hit KO strategies.
