Eye of Hurricane costs 3 skill points and is Star Lords ability where he spirals up into the air, lobbing several grenades below dealing moderate damage.
This is activated in battle using the
+
You want to get a bunch of enemies to about 20% health before using this ability for it to defeat them. Checkpoints can be reloaded to farm this out.
Warning:
As mentioned in the forums some achievements seem to stop tracking either between selecting new game plus, or using the additional in game save slots, so finish this achievement off as soon as you can.
A solution that worked for me with a stuck tracker:TLDR - Complete all other achievements, Delete save data, start new game, unlock hurricane ability, took me to first bunch of enemies in chapter 4 to do this.
I was stuck on 85% for the Altitude Adjustment, I had used all 3 save slots and played through most of new game plus to mop up the rest of the achievements, and was unable to progress this achievement.
I decided to delete my save both local and cloud from the manage game and add-ons menu on the Xbox dashboard. Then started a fresh playthrough.
I played up to one but last fight of chapter 3 to unlock the hurricane skill as you have to spend 1 point on the first ability and save 3 more for the hurricane skill. Then decided to play further into chapter 4 on the Rocket path for more enemies and the achievement started tracking again and unlocked at the first available fight using save reloads.
