Bombs!

You can rabarta, gifoie and Razonde through doorways.

I remember on PSOnot+ with my Fonewearl, you could shoot Megid through the doors also.... but not in PSO+. In not+ I heard you can also use God/Techs to raise your techs past level 30, but I don't know about that.

Dark Falz kind of gets easier because you get better weapons and stats, but in Normal it's hard if the only weapon you got is "Saber+2"

There's also the (really fast) left-right-left-right-left-right-etc. on the control stick to break out of freeze.

You can also use Ryuker to escape being swarmed by enemies (usually Rappies).

If you're about to get it by something that'll kill you (G-Sorcerer's Megid, for example) and you have 100 PB, you can do the Photon Blast and you're invincible while you're waving around your weapon in the summoning circle.

If a Poison/Nar Lily paralyzes you, you can just get poisoned by it and then use Anti (but not with Obs/Mils!)

Most of these are just tricks for newbies, but I'm sure they'll help someone.
