There's lots of easier ways to learn LUA.
Step 1. Go to
http://www.mmowned.com/forums/emulat...bossfight.html ([Guide] Creating a LUA bossfight!) and read it through
Step 2. After you have learned to create basic LUA bossfight go to Ascent Emu forums (or just search here) and look at scripts other people have made. LUA is very logical. And remember, practice makes perfect.
After you can make bit harded scripts, you can look at different Events and Commands at wiki.ascentemu.com/index.php?title=Lua
