Well GG then :P That's 5/6 of all the dungeons and shadow missions and monsters in the game cleared immediately ._. Mabi was fun til it lasted. You can use frozen blast on most enemies, only a handful are locked. I believe last I tried you are capable of using frozen blast on NPCs in MA, just that they won't freeze because of the cp restriction
Btw, you'd wanna use a better analogy. You can actually fire IS as long as the monster is in range
Try firing IS against the boss wave of NPC or against a grim reaper.
"Cannot use against this target"
Certain healers in NPC too cannot be targetted either.
And frozen blast is a max 1 minute with elemental wave taking longer to rearm and such.
Frozen blast was such a trash skill, now it will be useful again.
Like it once was before all these high CP enemies.
Pretty much anything boss tagged you cant freeze, with certain exceptions i think. I havent used alchemy in a long time, since before they changed the basilisk to be immune to frozen blast.
So i don't know what tags the enemy must have, might be the same tag used for IS
