How can I change spells into the mass?

[jongwoo]

For instense, I'd like to make mass slow, mass dragon arrow, and mass divine armor.

So I searched, and found PCbun's reply about mass slow,that I need to change the spell.lua.

Then, I'm totally lost in spell.lua that I cannot find anything in common about mass- supporting spells. :confused:

Can anybody help me out?
