Hi

I need some advice what do I do with a Eruption Channeler i see it gives 50 attack on volcanic but someone once mentioned can be better used on a demonic planet I think

So what does it do on a "Demonic planet" or is it Just a useless drop from a NPC (Lazuli Factory Complex)

Or maybe I must go and search it on wiki?

Thanks in advance

It is just as useful on one as the other (given that one is an upgrade).

But that is just me.

What you do, is you wait until your passive attack is maxed an then demonise it. Unless I'm getting it mixed up I'm pretty sure that is the way you get the highest passive attack...
Use it on your best volcanic, then transform it when you get the passive attack maxed.

There is no useless Lazuli Factory Complex drops and the closer I get to level 601 (when they disappear), the more I want them.

Eruption Channeler give you +50 attack for a maximum of 1000 attack (sometimes 1050, don't ask). Volcanic planets get upgraded to demon planets so use them on your volcanic planets. I can't confirm if they work on demon planets so I'm making sure to max out the volcanic planet before I upgrade it. Assuming they work on demon planets, there is no difference in using them on one vs the other.

This is important and I forgot this. Max your volcanic passive attack (again, 1000 or 1050) then transform it and get another 800 bonus attack. If you make it a demon and then try using the channelers, I think you are stuck at 1k.

ODragon once again you come with a useful and well constructed reply +1

One thing I forgot.
There are ways of getting higher.
