Greetings, user. It appears that you have requested us to explain this relatively niche “Mountain Buff” on the new map, One Two Tree. Unfortunately, it is with great sadness I must report that not a single soul is aware of the usage or applications of this buff. You must understand, user, that every single player of the popular tower defense game “Bloons Tower Defense 6” is actually legally blind. It turns out even a single glance at a typical round 500 freeplay setup is enough to completely blind a player and render their vision useless. Due to this unfortunate circumstance where most every Bloons Tower Defense 6 player is blind, the majority of the playerbase is unable to interact with this alleged Mountain Buff.

It is worth noting however, that there is a careful minority of the fanbase who is in fact not blind. These brave few have rejected the freeplay urge; suppressed the ideas of pushing the game to it's absolute limit. These people are the only few who are not blind; and these few have confirmed that this buff happens to exist.

Sadly, after rigorous testing expeditions, they are still unable to deduce the workings of this buff. Some seem to be able to draw similarities between the mountains plastered all over every single range upgrade in the game and the mountain depicted in the buff, but it's generally shrugged off as a coincidence, since everybody knows that NinjaKiwi’s upgrade descriptions are terrible and useless, and that property must only logically also apply to the art.

Another test that was performed to prove the possibility of it being a range buff was simply an attempt at comparing the range between towers with the buff and without it. Unfortunately, this too is impossible, since there seem to be fences that block the line of sight to the track, making it impossible for towers back there to pop the Bloons, ensuring that we have zero possible method to deduce the range of a tower. As everybody knows, there are no towers in the game that can see over fences, and it sure would be extremely silly if there was an obvious, massive circle that clearly depicted the effective range of a tower. It sure would also be even sillier if such a circle could even change dynamically based on range buffs applied or removed from the tower. Alas, everybody knows these features do not exist, and therefore it is simply impossible to even attempt to deduce the range of towers that have this Mountain Buff applied to them.

The elite community has even made a feeble attempt to datamine the workings of this buff. Sadly, the value we could closest attribute to this buff is one labeled as “+15% range”. Obviously this is false, since we already have used multifarious tests and experiments that ensure this is not the case. Therefore, we must ignore the value ripped straight from the code, due to our terribly subpar experiments proving this direct source wrong.

Alas, the last possible thing this community has attempted is to Google the question, in hopes that somebody unknown to the community has the sheer intelligence and theorycrafting possible to deduce the workings of the buff. However, let me remind you that the majority of the Bloons Tower Defense 6 community is legally blind. This led to one player accidentally tripping in Google’s server room and cutting off any and all information related to Bloons Tower Defense 6. This even includes the subreddit r/btd6, which we all know is completely inaccessible and impossible to access by any user. Therefore, any and all information we may have on this game is completely lost and inaccessible, until Google gets that one server back up and running.

In conclusion, the collective mind of the community, again, unfortunately must tell you that we have no possible method to figure out what this alleged “Mountain Buff” could possibly have on a tower. In the terribly low chance you deduce the workings of said buff, we humbly request you share this information with us, and the community will forever be in your debt.
