Is It Worth Getting The Solar Amp To 200 Or Keep It At 160 And If It Is Worth 200 What Are The Benefits ?
The benefit of Solar 200 is it installs Empowered Channeling Hand Mod, making room for Max Damage as actual Hand Mod for 2% increase. At 160 it already gives you 5% Might. Up to your friend to decide if 2% increased damage is worth 1mil XP.
There's not a lot of tangible benefit in leveling it past 160 in terms of damage potential, as described it just enables empowered channeling and increased health which won't benefit you because you won't be running the Tetra anyway, the controller will be. Probably not worth leveling in my opinion unless the OCD of having it 160 triggers you. Surprised anyone is running Empowered Channeling over Max Damage anyway, not worth it for the rare occasion you might be lunged in content that actually matters where the tank is/should be taking those lunges. Just take Max Damage anyway.
If you have the xp and seals and nothing else to level might be worth it in the long run if you use channeled powers a lot. Usually getting lunged isn't a huge deal anyway but it will just save you the annoyance (which is pretty minor lol). I fed my max EoG into solar amp like a dummy not even considering whether it was worth getting past 160 but I'll probably level it to 200 anyway just because I don't have a lot of other arts that need work.
It also gives you a 5% Defense buff while in use. Not enough to make a difference if the Boss looks at you the wrong way. But those annoying adds could easily be ignored for awhile.
Acknowledged, but still not worth, I'd rather take the damage, motto, if its dead I don't need defense, but I appreciate what you're saying.
I spent by far most of my time in Open Worlds, Solos, Duos or Alerts without Tank. Getting lunged before HV goes boom triggers me.
While it's true that empowered channeling isn't all that, the base stats that solar amplifier gives are really good. Even if you don't plan on doing that last breakthrough I wouldn't dismiss throwing nth metal into it unless you have other artifacts you're eager to use.
