renewal and attunement and pixies are nice but...
thunderstorm and essence of wind (92 for 100% cast) can change entire fights
getting off thunderstorm (fast cast) will reveal those pesky stealthers AND cripple opposing casters faster casting recovery, in addition to dealing light damage
getting off essence of wind (slower cast) will cripple opposing casters faster casting, in addition to dealing moderate damage
get both off, you have effectively neutered opposing mages/casters for enough time to wipe them out.
ideal for choke fights, but thunderstorm is fast enough to cast open field fighting
layer in wildfire (106 for 100% cast), you and a couple of other mages can push through any choke against incompetent opposition
