183... wow, thats high even with 10x experience i've never been that high, anyway about serpenter's problem, before you can go into the Tower of Mana you need the key from a pastor, he'll be at the Tempel of Wind, someone in Luin will tell you and Sheena will not join you until you have fought her twice and Luin is destroyed... and I apologize in advance if anyhting i say gives anything away for you as the game does have a lot of secrets and plot twists... oh and guess what, i got a new gamecube i can go back on T.O.S now yay!
