Ofc get third summon

Won't it just eat chakra, and doesn't add any meaningful ? Isn't better to do as i wrote? What do you base on saying "get third summon"?
Sorry, i need normal answer, not dumb. With reasonable explanation.

In my opinion, get the third summon which is Gamabunta .. Gamabunta gives more power/atts than the Serpent .. After getting Gamabunta, make him and Katsuyu as your 2 main summons for GNWs .. Feed only 2 of them and forget about the Serpent .. Its not gonna die or disappear if you let Serpent starve for ages .. xD

By feed, you mean level up? But i know, that having 3 summons for some smaller (also ~12 actives) groups, is giving headache, because it drains a lot of chakra per day.
I mean, if there's not enough chakra, % of summon drops, and you lose power.

Assuming you havent gotten slug yet and your snake is fully leveled then it might actually cost you chakra in the long run, were you to recruit the summon just to then not even feed it. That's because the summon is recruited being fed. At that point you wouldn't be leveling the slug either and the attributes it would try to give are basically nothing anyways.

Having said that, I'd recruit the slug. Now, you might actually lose a very little bit of power in the short term with this plan... but it wouldn't take very long to eventually even get more power out of 2 active summons by recruiting slug and then starving your fully leveled snake instead.

A starved summon still grants 40% of its attribute bonus to the group. With around 220k, I think a starved snake versus a full-fed max-leveled snake is a difference of about 600 bp - not much, really - but not nothing either.

So... I would suggest you recruit your slug and start feeding it so that it can get you better bonus from being leveled - might as well start leveling it now because it takes quite awhile for a summon to level up to max and it sounds like you guys are behind the curve already.

Basically, feeding all 3 summons is a lot to ask for most groups... but you still want all of them max-leveled, even if you're not planning on feeding all of them.

Sorry, i didn't wrote. We do have a slug, and i didn't touched the snake. Was saving everything for leveling up slug. Was planing to max out slug, and some day, in far future, with more members, max out snake. Until then, just farm coupons on it. I personally don't find frog as useful as others in gnw, so it would be recruited only for bonus power. But i wrote all my concerns about it above.
Also, does summon consume more chakra, as it levels up?

Learn how to read, because you clearly still don't understand what these 2 told you yet. Basically what they said:

1. Fully leveled, fully fed Bunta is stronger in battles and gives more power to entire group than fully leveled, fully fed Serpent.

2. Yes, feeding all 3 summon is near impossible. They are telling you to let Serpent starve and use the chakras you'd normally use on Serpent to lv up Bunta instead.

3. Yes, in the short term future, you group BP/gnw will suffer since Serpent will be starving and Bunta is still leveling. But in the long term future, it'd be better than your current situation.

In the end, ask yourself these: How long do you plan to play? How long do you plan to stay separate as an inactive group? Because in my experience, inactive group like yours usually just end up merging into a more active group. So if you see that as an eventual future, do whatever with summon. It won't matter anyway. But if you plan to stay for a long time and don't have/see any such plan, do as they advice and get Bunta, start leveling him, and just abandon Serpent. By abandon, I mean, stop feeding him, you can still do summon capture to farm cps on him.

Actually, if he's not an older server and the group is still new enough to have max-leveled any summons then I would say he's right at the moment NOT to recruit frog. Keep leveling the other two and wait to recruit frog after snake is max. At least snake would give you slightly higher attribute bonus when starved then and much more awkward long run to think about starting to feed snake in future otherwise.
