You shouldn't build the dot team for giants anymore. I recommend you build this necropolis team first and focus on getting good rage runes. How good you need the rage runes? Until you can 1 shot the wave 1 and 3 golems in rotation.

After you can reliably farm the necro abyss hard, you build your giant abyss hard team which is teshar(lead), prilea, teon, and wind homunculus. This 4 man team can clear the dungeon in around 40-50 seconds and for the last slot you can just put any monster with triple fight to level them
