Ask an Aran thread.

Monsters stay in the air if you can KB them as they are falling. You train with final toss just as a way to add extra damage if you can't 1hko/2hko. It really helps to add damage to a large mob where Aran's get their damage distributed between them. It only activates after triple swing if you press up and attack. You can decide between many moves after triple swing, or not, so it doesn't activate after every triple swing. As for maxing it, I don't really know when the best time have maxed it would have been. Definitely max it before Combo Peril though.

Thanks for the answers. Final Toss is a difficult skill to calculate the damage for the Aran Calculations I'm doing. If for example when you do after Final Toss another Triple Attack, and the monsters are airbone with the first 2 attacks and not anymore with the third attack, plus you do Final Toss after every Triple Attack, then it would be calculateable. But as I see now, Final Toss is an unpredictable skill. =(

I have another question. Is it true that the last attack of Triple Attack has spread out damage? That means that when for example the skill is maxed, not all monsters receive the full 250% damage, but a fraction of it like the warriors Final Attack? Are there other skills with spread out damage? Otherwise I have to rerun my calculations.
