As i understand, Necromancer players will have a choice between "good or evil."
A good Necromancer could connect himself with a "spirit realm" and recieve help from the spirits who were once a part of the living world and met their untimely deaths due to corruption spreading across Verra. Those spirits could provide help in a form of:
-Faster mana regeneration (for certain period of time)
-Gaining control of nearby mobs to fight for you in a battle
-Random buff or purify debuffs when in combat (haste / faster casting / defense or attack boost, etc...)
-Resurrect (at random, depending on how low a players corruption "meter" is)
-Summoning a ghost copy of a corrupted player a "good necromancer" has killed last
-Summoning an Archangel (good Necromancers ultimate skill)
An evil Necromancer was for ever caught in limbo between life and death due to unfortunate event that occured during a Necromancers questchain. In order to escape this cruel faith, he made a deal with the Death. Death would spare him of his faith in exchange for souls he accumulates in his future path, making him for ever linked with the Death. Necromancer would also gain the abilities, such as:
-Summoning skeletons and/or spiders (tier 1 summoning)
-Summoning zombies and/or ghosts (tier 2 summoning)
-Random debuff when in combat (decay / slow /weaken the attack or defence / stun, etc...)
-Conjure a ghost shield, sacrificing souls to protect him / receive less damage
-Summoning spectral dragon (tank / tier 3 summoning)
-Summoning Death itself (DPS / evil Necromancers ultimate skill)
Necromancers could also use somekind of a "soulforce meter" (similar as mana), to use when summoning creatures. This soulforce meter would gradually fill while killing mobs while questing, or other players.
This idea may not be good but, to me it seems it should be fun, so i decided to share it

I would appreciate anyones honest opinion about it.
