Double post... >.> Because I have to post this.
Optional boss/dungeon: Undead Giant 2.0... this bastard is armed with a scythe arm on its left side and a club arm on its right side, chains attached to its back and with a peculiar growth coming out of its lower back.
It is a freaking monster. Each attack is capable of chewing off half your life, if not 80-90% of it. First encounters, I've tried co-oping with a friend against it. But I kept dying like a scrub. It was clearly a waste of time for him since we couldn't beat it, even if he is too bro to say it.
So there is the dying to the Undead Giant montage on my own.
In its enraged state, many of its sweep attacks incorporate the chains on its back. The chains function as a range increase and also extending the attack so that even if you time your dodge right for its initial swipe, the chains will hit you anyways. This is a death sentence.
You cannot be timid in its enraged state. If you step back it will sweep at you with its forward swipe. The chains will murder you with that extended range.
It has a range of attacks...
It does 2 swipes with its scythe arm. Its the worst when you get into a groove, where you are used to UG swinging once, you dodge it and hit it... it becomes UG swings, you dodge it and move to hit it, but get swiped by that second hit. This one teaches ya to wait for at least a few milliseconds longer before moving in to attack after it does a scythe strike.
Its spin attack, where the chains hit you if you try to counter too fast. Teaches ya not to use the counterstrike function.
Its smash the ground attack, it tends to repeat it between 2-5 times. Dodge to your right for two of its swings, you should be far enough that its 3rd swing won't hit you. Hit it in that time frame.
Its foot kicks while you are up close to it, I never seem to be able to properly dodge those. Probably cause I wait a millisecond too long for the windup. Might be a visual problem and/or its cause I'm in the wait for the right time to dodge that scythe mode.
Enraged mode
Forward sweep+chains, always happens when you are in front of it and kinda far. It will murder you. Don't ever give it the option to use this attack. Get back back to your position, suppress that survival instinct to run away and heal when injured. Continue dodging its other attacks, instead of attacking it, use that time to heal.
Ground smash, easiest telegraph ever. Dodge at right time or out of range, hit it.
Fancy spin, another big telegraph, the only time that you distance yourself from it... and you should get back close to it as quickly as possible. (At least I do.)
Here is the thing though, you can influence how it'll attack, depending on where you stand relative to it. The position is near but not too near the UG's left leg. Well, to the right of the UG's left leg, standing in front of its scythe arm. It'll favour doing the easily dodgeable close range scythe swings and spin attacks, even during the enraged mode. But, its a little harder to stick to that sweet spot during enraged mode, since it might throw up one of its enraged mode attacks, at that range, easily dodgeable/avoidable. You essentially spend your whole time hitting its left leg.
Oh yes, that growth on its back I mentioned earlier... if you destroy it, it does straight up 25% damage to it, save it for last, during its enraged mode. Ideally the best time to hit that growth is after its ground smash, since it'll likely have its back toward you.
If you keep hitting its left leg, you can end up staggering it, where you can whale at it before it gets back up. I'm not entirely sure how the fancy visceral attacks work, but I managed to do that once, ever, for epic damage.
If you semi-stagger it, you only have room for 1 extra attack.
