Energy Bolt: Not very useful as a DPS skill, but is useful to get a group of mobs chasing you to back off, and to push smaller mobs around a bit.
Sleep: Wouldn’t know about it now, but I thought it was good in iCBT2, probably still is. And there’s an Energy Bolt damage boost attribute.
Earthquake: Idk why but I put 5 points into this, I really shouldn’t have, would have been fine with just 1 point. also not great damage wise, but can keep mobs airborne for a bit to give you some time to cast certain skills
Lethargy: don’t know, don’t use it. sounds better than the current Reflect Shield.
Reflect Shield: used to be useful in iCBT2, now it’s absolutely trash, really wish I didn’t max this before actually trying it out more, I just assumed it was still decent.
If I could redo these, I’d put 1 into Earthquake, 5 into Energy Bolt, 5 into Sleep, and maybe throw the other 4 into Lethargy or max out EQ.
