This is my current build: https://tos.neet.tv/skill-planner#2137733gg.1521354351.18213f5a617585.11243a4a55.2a3146657385
I’m just class 11 on FF2 for now, but I’m going with that since I don’t feel the need to max out Levitation, my BC combo needs to wait out the Ice Wall cd anyway.
If you really want to pump Ice Blast, I guess go for something like this: https://tos.neet.tv/skill-planner#2137733gg.1521354351.13213f4f617585.11243a4a55.2a3146657385
Subzero Shield isn’t that useful in PvE anyway.
We still don’t know if more walls = stronger Ice Blast, but then again Frost Pillar is getting a shorter CD.
It should deal big damage to linked targets if you have a good weapon.
