Thing is necros need Wiz3… So people are trying to figure out what to put inbetween to make necro viable. That is one of the better builds since sorc pets do hit like mac trucks in kToS with riding skills. Jump off spam two flesh cannons, jump on pet go do pet things.
That all said, Necro3 in particular is a trash option right now, since the flesh meteor is buggy and difficult to use. Without exploding your Shogg the AoE size is one of the smallest hurt boxes in the game. To blow up your own shogg it also has to be directly on top of a particular part of their body. The targeting is absolute dog ■■■■.
That said cryo3 is also trash without chrono and doesn’t lend it self that well to summons.
The linker in that build is largely a pointless filler because there is basically nothing better to stick in there. If nothing else you can at least gather the mobs with linker1 and get some bonus dmg.
Coming with the brand new kToS patch Thaum1 will have more viability because of a static 300sec duration on swell arm. In combination with swell left’s shrink attribute it’ill become a viable option.
