Brand of elements and unstable elements.

[Kiroh]

Also destabilization only occurs on failures.
Believe me, my Alchemist VERY happy she took a trip to Weaver to get Brand of Lightning, goddamn destabilizations have been screwing me up all the time.

Well actually the brand skills stabilize any element, the only difference is when it's not the element of the brand you only get 20 Quality, when it is the element of the brand, you get 100.

(Still, that extra 80 quality is totally worth leveling Weaver to 20 for xD. )
