i like this guide , however i think that second option is more effective , since magis will not deal alot of damage to kill in pvp , especially against es sorces or elemental druids it will take forever to kill those characters with magis, or summons since if u wonna get that close u will take damage too like from tornados from druids which will kill u at the moment u tele at him , ur best choice is use nova and max synergies and basically use summons for stacking minions as shields and maybe to kill when 1hp left by magi casters or caster revives . i think that is best choice and 3k nova will not kill anyone even with lower revives u will need around 6k to deal good damage
other than that i think ur guide is very good and very helpfull and i would like to build one (i like necros alot they r my favorate) and i think this build is even better than bone necros since it has less weaknesses and can own more characters
