What Spell packs to DL

I've been browsing the "demo maps" section and have been impressed by the JASS and GUI enhanced spells. I noticed that many of them require an engine made here to work.

If I were purely going to use JESP spells, what would be a short list of all the resources I would need to run them (like I keep seeing Vexorian spell system)

Look inside their readme.

Knowing JESP spells, they most all need either Handle Vars or Vexorians Caster System, and some that require the JASSNextGenPack (vjass) but most need Vex's CS...
