Here’s a combo involving dropping all skills on a mob such that they stay grabbed/juggled throughout a 12~13s combo. It’s enough to dump out 1st and 2nd awakenings, Executioner’s Slash, Living Dead, Guillotine, and Grasp.
I specifically designed it to one-combo Rosaura in Luke raid duoing with a sader, but this is more than enough to incorporate in fighting juggle-able enemies like Nerbe, Taorik, and some other raid mobs for other Necros.
I’m using rental weapon and non-swapped DR/Pledge to lower damage enough that he actually takes the full combo.
The black wave timings are fairly specific (to either keep Borodin in position for LD or to scoop him off the ground so he can’t recover. The X-axis positioning also is kind of specific so that 2nd awakening hits him more consistently while he’s not dragged directly into the orb.
Zombies are fairly annoying to do solo, but you shouldn’t have many problems in a raid party setting. 2nd awakening can fix a top platform, 1st awakening can fix most/any platform.
The real annoyance is that for solo/duo, you’re very carefully killing zombies on the proper platforms. But that’s not something you really have to worry about as much in a raid party.
Yes - the raid layout of the dungeon has a solid door that can be used to prevent Mateka from appearing behind you and eating Vallacre. You can then use that to Grasp/Executioner CK.
You can also do more than object cap with LD and some other skills active at the same time, so doing more-than-usual object damage or even object killing wouldn’t be impossible.
It is definitely casting speed. You can convert or try out casting speed hat/hair avatars and see the difference yourself.
Tome changes are beneficial for the mini-dungeons (BG, hatches in Anton, Energy in Luke) and make the shorter/smaller dungeons more consistent (not relying on RNG for soul drops for zombies and trash mob kills).
But, the nerfs to non-cube skills basically revert any buffs that Tome did in the first place. DMG is arguably worse than before Tome since it almost never got to full duration and full number of hits anyways.
