No, 'Channel' isn't:
[hidden="Important Notes]
Life Drain does not work with this system, so you should use a triggered version of this spell if you want to use it.
Same for Finger of Death, if you want to use this spell bug free with this system, you should use a triggered version of it.
If you use damage modifiers by setting the damage amount variable, you have to use GetUnitLife, GetUnitMaxLife and SetUnitLife instead of GetWidgetLife, GetUnitState for UNIT_STATE_MAX_LIFE and SetWidgetLife.
The boolean udg_PDD_SPELL_RESIST_AUTO_DETECT is only neccessary set to true if you want to use a customized damage table with spell damage resistance above 100%. If this is not the case, it should be set to false, as the system is faster then and still works correct.
As already mentioned you can't use the spell reduction ability when using this system (runed bracers and elunes grace). If you want to use them, you can trigger them by using the damage modifiers. Runed bracers is already considered in this system, so you don't have to code it.[/hidden]
But it still looks like it is, I've tried to change the spell order ID, but that didn't helped at all, does this mean I can't use any spell based on 'Channel' in my map with PDD?
