Skeletron Prime [Malice, Death, Defiled]

UPDATE: Unicorn Mount was nerfed in 1.5.0.1, it's capped at 49 mph. I have 61 mph because Luiafk reverts this change, so technically this method is not working.
Old description:
Here's a little guide if you're like me and stuck right after fighting Cryogen because the next Malice bosses are way too hard:
For the first phase do what I did in the video - simply run at one direction using unicorn mount, Prime probably won't even hit you. Go for the Sawblade hand first, because sometimes it can stick to you (0:28).
Phase 2 has a simple pattern:
When Prime is circling you - RoD out (or jump with a sandstorm in a bottle), dodge the skulls (1:12), and then there's 5 rockets + quick lasers attack, which is the hardest one to react at. Try to go down at that moment (2:00), dodge (or get hit), and then the pattern repeats itself. It becomes easy when you manage to do it for the first time.
At around 50% there's a new attack which comes after the circle attack - spin+lasers, not hard at all, simply jump over horizontal lasers, do not fly away (1:45).
The final phase, which comes at around 25%, changes the pattern a little bit, and adds a rocket attack. I would recommend to RoD out when Prime fires his rockets, and simply jump out at high speed when he does the circle attack. Rockets can be bitches sometimes and if they really want to hit you - they will, so don't be upset about it.

" do not fly away" so thats why I dead about 60 times after final phase. Hope it will be easier w/o wings haha.

Почему мне Скелли напоминает Горшка? Всмысле солиста из "Король и Шут"

[@PrismaAce]

[@qwerwrethsw5fssss]

Try to reforge every accessory to Quick, it should help

@@qwerwrethsw5fssss already is

[@qwerwrethsw5fssss]

@@PrismaAce make sure to have all the movement speed potion effects, and the movement speed candle from Drunk Princess NPC.

@@qwerwrethsw5fssss found out blessed apple got nerfed in 1.5.001, wondering how you managed to still have an full 61mph on malice mode when it was nerfed by 20% to 49mph

[@qwerwrethsw5fssss]

@@PrismaAce I just checked it, the speed is at 61 mph, so I have no idea what's going on. Here's a video: ua-cam.com/video/rRknUbNwdLI/v-deo.html
Also I'm dumb and for some reason I thought that the new movement speed rework includes mounts, which is not true at all. Mounts just give you a flat amount of speed and you can't change it in any ways, so my previous advices are useless :d
