It has some pretty difficult boss fights that almost require safe spotting/advanced tactics unless you are REALLY good at this game. In particular...the last two fights at the quest's end are quite difficult. Luckily, there are some strategies that make the quest possible for mid level acoounts
The penultimate fight (hardest part imo) has you go up against two Level 141 Tortured Gorillas and two Level 275 Demonic Gorillas. They use all of the different combat styles, and the latter two use protection prayers after you have done enough damage in one style, meaning you have to gear switch as well. Worse still, you have to fight two (of the four) enemies at a time, and Nieve who fights with you doesn't help much, which means you can't use prayers easily to mitigate all the damage you will be taking. A Demonic Gorilla comes in after you take out a Tortured Gorilla, and they hit really hard. It took me three tries as I (somewhat) got the pattern down of gear switching/prayer flicking, but even then I was only able to defeat two of the Tortured Gorilla and one of the Demonic Gorilla. I may have been able to defeat the last one had I had higher combat stats and better Ranged Equipment as well as was more comfortable with gear switching, but I ran out of food, so I just hid while Nieve very slowly defeated the last Demonic Gorilla. I used Void Knight equipment with a change of helm/weapon/some armor as my gear switch by the way. May not be the best, but using Void Equipment means I have to switch less equipment and can bring more food, so that's the choice I made. It worked, kinda anyway.
The final quest fight has you against an enhanced Level 431 Glough who has 3 phases. You look online and all the people beating him fairly are almost maxed out...so I used a Magic Longbow (cheap weapon, I know) and safe spotted the first two phases. The last phase can't be completely safe spotted, but you can use hit and run tactics to chip him down while minimizing damage.
I beat the quest with melee combat stats in the 70's and Ranged in the mid 60's, although higher stats would probably make it easier. The main reason I beat it so early is because it opens up the fastest way to train Ranged. Again, planning to get to level 75, get a Toxic Blowpipe, beat the Level 700+ Jad in the Fight Caves, and get a Fire Cape.
Also, the final battles' theme "Monkey Badness" is such a great musical track. Glad to have unlocked it.
Man what the fuck. That sounds like some serious bullshit lol
