That's true, i'm a nobody. Don't listen to me. By all means, do whatever you want to enjoy the game...

I would rather 'charm' Yoshimo and take him with me into the Sphere so he can set off that trap for me, than use cheats ;)

Why not just make your game a duo or trio? I actually find those types of games more fun than a solo. You'll still level up way faster than a regular group of 6 so by the end the party is all-powerful, you can benefit from the NPC's quests, and you won't have to worry about whether the game is a "true" solo.

I'm just thinking that if you couldn't get past a trap in the Planar Sphere as a solo sorcerer, you may run into quite a few more challenges that you're not quite ready to take on solo. Play the game through a few more times with some backup (i.e. NPCs) and then try again.

Ah, what the heck. Just play the game and have fun with it.
