Kyikk

Strategy
Keep attacking with Tidus untill he has reduced Kilkk's health by 750, this should take about 5-6 attacks. Then the battle will be interrupted by a group of people, one of whom rushes to Tidus' aid. You will now have the 'Special' option, this has 2 skills to offer; Steal and Use. During the first round after the interruption you will have to deploy the Use function, by throwing a Grenade (Final Fantasy X). Also at this point Klikk's HP is fully restored, but Tidus' HP is not restored. So if needed be use a Potion (Item) on him. But from this point on all the need to do is attack with Tidus and keep throwing grenades with "???? ". However you do not have unlimited grenads, so you need to steal some back (This uses up a turn).
