Or you could do what I did and just jump right down the center of the colosseum and start wailing on that stupid horse fucker. Banzai!!
I'm always hesitant to engage Lynels head on even with good weapons, armors, shields, and being stacked with food/potions with health, attack up, and defense up effects. Are they still able to one hit kill even if you have the best armor and shields available? I swear they have one move that can always one hit kill regardless of your health and defensive levels.
I picked up Blops II tonight to see what I can get. I noticed I had the FAL available for unlocking, so I decide to go for finishing up my ACOG optic proficiencies. I just need three longshots with an ACOG'd weapon. It took over 90 minutes before I got my three longshots despite all the bullshit that happened. Ugh. Lag out the ass, lag comp against me, getting disconnected, getting shitty maps that are not long range friendly, shitty team of randoms, etc.
I just now have the EO Tech and Hybrid Optic sights to work on for complete optic proficiencies. I miss having a silencer on my FAL. I hate it takes so long to get silencers for assault rifles.
In other news, no shrine there, but I didn't even know there was a colosseum.
Did you have a look? If you want to look back, I have a picture from my time in that place.
If you haven't already cleaned house, you best enter this place from the air. Get to somewhere high and glide into the upper levels of the Colosseum Ruins. There will be Moblins on the top floor, Lizalfos on the second floor, Bokoblin on the first floor, and one very trollable Silver Lynel on ground level. Get rid of the Moblins and Lizalfos with stealth if you can. Whatever you do, do not go on the first floor unless you want the Lynel on your ass.
If you packed some strong bows (namely the Savage Lynel Bows or reasonable equivalents), pack enough fire, shock, and bomb arrows (if you use ancient arrows, you will lose the Lynel drops or the drops from any living enemy you hit), and are good with bating with remote bombs, you can enjoy trolling the Lynel provided if you avoid getting spotted by him.
If the Bokoblin hear you, that's fine. They are too stupid to come up to your level. The Lynel can probably hear you from the second floor, but you'd have to be loud for a long period of time before he is "alerted" (the "!"). If you don't want to chance ruining your trolling, you can equip the sheikah gear for stealth. Just stay crouched to mute your footsteps (your voice and sound of your equipment are still audible though).
Then it's just a matter of using remote bombs to bait the Lynel (he'll have a "?" mark). Once he gets in range, let him have it and ready your arrows of choice to get some sniping headshots. Back off when he teleports. If he reappears and turns away from you, snipe him some more otherwise use bombs to bait him back to the area almost under your perch.
There's no way to really know unless the relevant police jurisdiction acts on any criminal activity with support from the Japanese government. Japan does things differently than American police and government after all.
