Anyone have knowledge of how scrolls work?
 

EDIT__
figured this one out finally. To give a random chance for a scroll...

find this in the arena.lua file approx line #255 (at least it is 255 in my arena.lua, yours will be this or close depending on mods)

The actual line reads:

function calc_bonus() --ftag:bonus

Then add these lines:

-- chance of scroll
if (Game.Random(1,100) <= tonumber(5)) then
Logic.hero_add_spell( "spell_resurrection", 0, 1 )
end

I have not tried to use numbers for the 'spell_resurrection" part yet, but my main goal of aquiring a rez scroll has been met. Also I did not use the random check in game, just put the logic.hero line in and fought one battle, so I won't swear the random stuff is right yet. going off memory and it's hours past bedtime, mind fried, later

End EDIT__

I'm trying to have a random chance to gain a random scroll after a battle sort of like the extra rune and rage/mana pot mods do. I can not seem to figure out what the exact call to add an item is for them. Does anyone have this knowledge?
