Sacred 2:The most powerful protective CA in Sacred 2. How "Expulse magic" works

This is incomplete version. Originally written by Mibbs (in russian). Translation by Mibbs.

The first thing you should know, multiple castings stack. It means that all effects of Expulse magick (Detrimental Magic Effects -x%, Block chance: Combat Arts, Chance to Fear Opponents and damage against some types of enemies) overlay the previous with diminishing returns.

There is one interesting property of EM: banishing potential.

To describe this property is used the string entry2 = {"et_banish_spells", n1, n2, 0, 8 } in configuration file spells.txt, where n1 is the base banishing potential, n2 - increase of banishing potential for every memorized rune.

Is it possible to caste CA by opponents in the EM circle? - Yes, possible, regardless of the banishing potential.

What does EM? - dispell the effects of Spell Damage Based Combat Arts (further CA) in the area of the EM circle; any projectile of CA is dispelled (including summon of creatures and traps, elemental missiles, spit CAs of the weaving spiders, meteor shower, etc.), a short buff on the opponent or debuff on the character is cancelled. Fields of damage (for example ice field of ogre-defender) are dispelled too.

CA is dispelled by EM if:

1)The Projectile of CA crosses the EM circle;

2)Creature with an active effect (short buff\debuff) crosses the border of the EM circle;

3)Banishing potential overcames difficulty class of CA.

There is no effect on the CAs type "lightning", "ray", "dragon breath", "sonic scream", "poison fountain of zombies/poison elementals, etc.", and also on permanent buffs.

What about difficulty class of CA: every CA has its own difficulty class, depending on its level. The higher level has creature, the higher level CA it uses, and the higher banishing potential must have EM to dispell CA used by this creature. The difficulty class compared with the banishing potential of EM: if banishing potential higher then difficulty class, CA is dispelled.

Overcoming difficulty class has 2 outcomes:

1) the difficulty class is overcome, CA is dispelled;

2) the difficulty class is higher than the banishing potential, there is no effect on CA.

Difficulty class is one of the few things in the game that doesn't depend on the difficulty level, I.e. for dispelling CA 100 level mobs on the "gold" difficulty need the same banishing potential as on platinum\niobium. Banishing potential can be enhanced by consuming more runes of EM, taking bronze modification "strength" and improving Delphic Arcania Lore skill.

Being equal level creatures can use CA at different levels and their CA can have a different difficulty class (for example on the Seraphim island and Wasteland champions of the same level throw a fire trap, with a difficulty class difference of 10-20%).

Bosses have higher difficulty class of their CA than the same level Champions, and champions have higher difficulty class than ordinary mobs of the same level. If EM dispells CA of ice elementals, it doesn't mean that EM dispells CA of elemental-champions same level.

The banishing potential >1000 dispells CA of champions and bosses highest (200+) levels.

On average for a confident dispel of all combat arts you should have the banishing potential about 5*CharacterLvl.

Dispelled CA can not be reflected.

Banishing potential does not affect detrimental magickal effects, root (which is a DME too), DOT, knock back and stun.

Hybrid Damage Based Combat Arts are not affected by EM.

Note: "Expulsive magic" CA has an interesting ingame AI bug: some creatures that have the ability to cast shortbuffs, in a circle EM lose available shortbuff, recast it again, lose, recast it again ... well just do that recast their buff, not paying attention to anything more.
