*Remember, poison work with PAtack and Physical DPS of Main Hand weapond but faces MDef.

===Formula===
MagicDmgDone (per Tick) = [ 2 * (ADF) ] * [ 2 * (DPS) * (0,75 {AoE Penalty: -25%}) + (BasePoisonDam)] =
= [ 2 * (ADF) ] * [ 1,5 * (DPS) + (BasePoisonDam)]
-------------------------------------------------------------------
MagicDmgDone (total) = [ 2 * (ADF) ] * [ 12 * (DPS) * (0,75 {AoE Penalty: -25%}) + 6 * (BasePoisonDam)] =
= [ 2 * (ADF) ] * [ 9 * (DPS) + 6 * (BasePoisonDam)]
====Modifiers====
*PoisonLvLModifier = 1 + 0.03 * SkillLvL 
*BasePoisonDam = Base Poison Damage, you can increas with upgrades of the skill (if it has).
*DPS = (Damage Character Tab.) -- Is affected by Weapon Speed Modifiers.
*ADF = Attack-Defense Factor, is based on (Attacker's PAttack) / (Receptor's MDefense) => ratio:
Ratio 	ADF
ratio < 0.2 	0.1
if 0.2 < ratio < 1	0.5 * ratio
if ratio > 1 	1 - 0.5/ratio
==Skill Improvements==
===Shadow Smash===
Icon	Skill Name 	Level 	Cost 	Cast Time	Cooldown 	Range	Skill Effect 	Upgrade
 	Poison Shroud	Elite 45	70 (+10,5Lvl) MP	1 second 	15 seconds	150 	Poison Shroud inflicts 40.0.. 1640.0 points of poison damage every 2 seconds on most targets within a range of 70 for 12.0 seconds and inglinges 50.0.. 950.0 dark damage to targets.	+16 and +90 per level
====Notes====
*Loses the cost of "1 poison bottle".
*Doesn´t up the poison effect time by 4 extra seconds, it may be a bug (text or programming?).
*The extra Dark Damage is True Damage and doesn´t vary with Attack or Defense, and it is done after Charge and before of Poison Effect.
===Erosion===
Icon	Skill Name 	Level 	Cost 	Cast Time	Cooldown 	Range	Skill Effect 	Upgrade
 	Poison Shroud	Elite 70	70 (+10,5Lvl) MP	Instant 	15 seconds	150 	Poison Shroud inflicts 40.0.. 1640.0 points of poison damage every 2 seconds on most targets within a range of 70. It also reduces magic defense and physical defense by 10%. It lasts 12.0 seconds and cause 50.0.. 950.0 of dark damage to targets.	+16 and +90 per level
====Notes====
*The reduction of defenseis casted before Poison Effect, when Dark (True) Damage is done. (Pending of Check!!!)
*Extra damage of Dark (True) Damage from Dextery, taken by the Elite 70, follows the next formula:
[ExtrDexDamage] = (0.20 + 0,035*[SkillLvl])*[Dex]
(tested :): Exedrax)
==Notes==
* It has a multiplier for Poison that dipends of skill LvL (x [1 + 0.03xSkillLvl]).
* An equivalence of total poison damage, when you get better attack speed (0.5 per second) and better weapons, is: 4.666 x Flammes (without Burst) - Calculated but should be tested.
