yeah, but as I mentioned, it’s range is really good, it can kill ogres on the the opposite path so you will never face them, of course it depends on your combo, in my case, without any range units it helped a lot.
Recently I saw a video by Mischreiber, he used on a top base max toxic forged not so many times, I think with 1.6 sec slowdown. So in this case, you don’t need to forge it that much to make a use from it.
Anyway, it doesn’t change the fact toxic cloud is a toxic cloud, the most unused spell it RR2 history. Even if it can be useful, as I mentioned, it’s rather for fun raids, not a must spell to upgrade, forge and use all the time.
Currently you can use every single spell available in game, all of them can be useful, which is very good in my opinion.
