Quick question, regarding healing techniques!

What do the higher levels of Anti / Alanti do? Resta restores more HP, I presume. Shifta / Deband / Jellen / Zalure increase in effect and/or duration, as usual, I'm sure. What about Anti?

Does the range increase? Are the higher levels needed to clear specific status effects, as in Phantasy Star Online?

I haven't been able to find much info on techniques yet.
