I actualy think Skellies scale with INT too, though I’ve never played a Necro and can’t confirm it.
You should not build an Elememe for PvP. There are many better builds for that aspect of the game, you should also go almost full INT, which is bad bad for PvP too.
If you are talking about your first char and want purely PvE DPS wizard, go Wiz 3 > Linker 3 > Warlock. It is hard but worth it.
Taking both Linker and Chrono 3 makes you pretty much support already. Even if you drop future ranks of Supporting for some DPS to make your game easier, it will end up not being worth it as you won’t even have a spell rotation, only the spells you get at some new R9 C1.
Even if you want to do that, by now nothing is worth enough for a Chrono 3 not to go Linker 3, the DPS que boosts of his party makes Quickcast (+50% damage for only himself, while not having DPS skills) way worse than more ranks on linker, honestly, both Enchanter and Sage are some of the worst R9 classes.
So, as I’ve already said before, Linker is a very good circle for warlocks, as is Wiz 3. C1 CAN kill a 5~6 pack of mobs, even with hit count, because damage gets really big in the end-game.
Pointing out again:
Wizard C3 > Linker C1 > Sorcerer C2 > Warlock C2 (DPS oriented Linker > Warlock, +5 AoE attack ratio = +3 targets to meelee players, 5~6 links on JP, summoning, salamion and +10 dark hits to any Warlock skill through Familiars is a pretty solid choice, please consider a Linker C1 has to be careful when partying as to not have it’s JP cripple by low damage attacks, such as lower rank DoTs, weak summons or anything like that)
Wizard C3 > Linker C2 > Necro C3 (No Necro C1 > Warlock, Flesh Cannon level 5 is not that great and not that needed on a Warlock’s C2 rotation)
Wizard C3 > Linker C3 > Warlock C2 (Meta, Linker C3 is future-proof and helps ANY party, Frost Cloud breaks any JP very fast and won’t benefit from it after patch)
