Lupa spirit channel
This is not acceptable. Lupa is far too easy to obtain as well. This makes it extremely easy to obtain a full team or an S-class. It's also extremely versatile to the point where it can learn the strongest fire, plant, lightning etc etc abilities and it isn't affiliated with those elements at all.
Overall, I suggest removing spirit channel. It can be a versatile and hard to counter monster. But the sheer power of a double hitting spirit channel or a bull's eye, or a double hit+bull's eye(seriously?) is too tremendous. I've seen it on weaker monsters and it was scary but reasonable. Lupa's speed+power+average defence make it overpowered.
If you don't remove it, you must lower the power by at least 50% to 66%. Maybe even lowering it to 45% to 33% and greatly increasing the double hit chance.
I personally can't stand seeing players like "goobers" boast about Lupa and not be completely honest about Lupa's position as the strongest monster. I treat all the players fairly and when they ask for advice, I tell them to forget it and focus on lupa. If the good players of the community can't honestly help the new players, what kind of game is this?
I hope you consider this wisely
