I was wondering, how does exactly elemental hail work? Because I can't see what are its advantages, and to be honest I can't even understand if is an AoE or not since it's not clear if it's a patch of fire or a fire tornado, but at this moment I was only able to hit single targets with it. My biggest concern is if this is an AoE since as a single targeting spell it seems underwhelming: at max level, it does less damage than a meteor strike, it cost much, much more and it doesn't seem to hit multiple times per time unit like burning wall. I understand that much of the skills are highly unbalanced, but until now the major problem that I read about magic skills was that a lot of enemies are highly resistant to spiritual damage, and this way a lot of the spells lose their effectiveness. Nonetheless, they still have a huge use against enemies with low spiritual resistance or whose resistance was brought down. In the elemental powers branch all the skills I tried had their usages (I'm missing elemental bolt, since the spellbook seems to be bugged, which I believe to be a more powerful and versatile meteor strike, and elemental strike, since the spellbook doesn't seem to exist, which I believe to be another upgrade for meteor strike), but elemental hail, for what I was able to understand of it, is instead totally worthless, so I believe I didn't understand how and where to use it. Anyone who can illuminate me?
P.S.: Sorry in advance for the possible awkward or incorrect English I used.
