The script above is my FireField magic script. FireField magic damage is not affected by Spell Damage and Magery skills. I want to set FireField magic up to increase damage under the influence of Spell Damage and Magery skills. Modifying other magic wasn't hard, but for me FireField magic is too hard to set up. Could you give me a hand?

It is possible to provide a damage amount as an additional argument for FireFieldItem (line 86) to override the default base value of 2 (per tick):

Code:

new FireFieldItem(itemID, pnt, Caster, Caster.Map, duration);

Modified:

Code:

int damage = 2; // increase this to increase base damage per tick

new FireFieldItem(itemID, pnt, Caster, Caster.Map, duration, damage);

Oh! Thank you. Thanks to you, I was able to solve another problem. I heartily thank you.

I have a question about FireField magic damage
