I beat Lady Yunalesca last week and I've just been searching around and exploring the hidden locations in the airship (Omega Ruins, Baaj Temple etc.) and I went back to Besaid and I came across Dark Valefor and got a complete ass kicking cos I didn't know it was there. Anyhow, I read that to beat them you have to build up your characters to have huge strength and be mint in the other areas. At the moment, everyone has at least 3,000hp with Lulu having the least but Auron and Tidus have almost 6,000 and both of their strengths are in the late 60's. I know I'm nowhere near strong enough to beat them and I have to get all the final aeons but I just want some advice on the characters strength bit first and if theres another way than levelling up through battles or if there is an easier or different way of significantly improving characters. Any advice would be appreciated and sorry if I'm missing out on something obvious!
