* Fixes#3259.
* Fixes SP damage bonus for levels 1-4 being too low caused by a rounding issue.
* Gate of Hell is no longer reduced by long range modifiers.
* Fixes the HP/SP damage for statusAtk and masteryAtk to properly apply the NK_IGNOREELEMENT flag when checking target players. This subsequently applies to all skills.
* Adds a new NK flag to remove any hard coded skills that can ignore long range attack modifiers from the caster's side.
