Spell Data
 

Some spells are described in the manual as being more effective if the mage is powerful like
# of effects: 3+

I noticed people in the forums know the exact # of effects per additional magic lvl. Where they get that i don't know, or is by experimenting.

Ex: I believe that enliven statues give 2 additional statues per additional earth lvl. (by experience).

Look at the "spell modders guide" in the modders forum.

The actual # of effects is:
(listed # of effects) % 1000 + (listed # of effects) / 1000 * skill.
% meaning modulus.

So, for example, 2004 effects would be 4 effects + 2 per skill level.
