* What bug does the patch fix? What features does the patch add?
Additional fixes to spell damage:
-Fixed double apply of SPELLMOD_DAMAGE to Seal of Command and Seal of Righteousness
-Fixed low contribution to Seal of Vengeance
-Fixed count of DotTicks for spells with additional effects ( fixes Mind Flay )
-Fixed channeled healing spells
-Fixed Tranquility spell coefficient
-5% penalty per effect is now flat penalty and applied after other reductions, this should make damage of spells like Frost Nova, or Blast Wave closer to official
-Cleanup in code
-Fixed level dependancy and damage modifier for ignite - now exact damage from triggering spell ( see tooltip ) with 8% of fire damage ( not increased anymore with spellmod_damage )
