New raid (4.3) mechs?

[MOZZYSTAR]

Yooo!
So, I did the lighthouse last night, and boy did we get WRECKED! It was impossible, but we somehow came over the impossible 800 deaths later.
This may have potential spoilers so if you have yet to do the raid and want to keep it a surprise, please don't read any further.
There were a few mechs that I didn't quite get and was wondering if any of you have thoughts, et cetera.

1.) The water one (I forget his name). Had this really big water aoe that I just seemed to love getting caught in. Did you notice any visual or written cues for when this happens, or how it'll be aimed, etc/?
2.) Gigas, I forget the name of the spell but all of the tiles become clocks. How does this one work?
3.) Construct 7 I HATE THIS ONE. He summons 4 # platforms (1-4) and changes your HP. My HP was turned to 5 so, like, everything he said just didn't work. :| What do you think about this one? If your HP doesn't pertain to any of the things he says, should you stay out of the platforms or...?

Construct 7 is all about simple math, when he says a number, your health has to be divisible by that number, and when he says prime, your health has to be a prime number. Whenever you step on one of those platforms, it raises your health by that amount.

1) Move your camera up when he is spinning his jug. It will eventually stop and draw water in, 3-5 sec later he will slam it on the ground and tsunami the direction where he drew the water in. Easier to dodge if you stand close to him. This mechanic was made to pick off those pesky casters that stay all the way at the edge and punish bad tank positioning.

2) Look at the clock hands spinning in the middle of the tile, go to one of the tiles where the hands are spinning slower than the fast ones. It's showing you how fast they will explode, so to dodge it, go to the slow one, (makes it easier if you just stand near the intersection/corner of multiple tiles so it is easier to dodge) then wait for the fast ones to explode, then dodge into the now open spot.

That's how I dealt with them anyway.

1: If you look up, the water is coming out of his cannon and pointing in the direction it's going to go in. Also since you're a caster, you can equip surecast just to be safe so you don't get comboed by the whole thing.
2: Some of the clicks spin faster than others. Sit in one that's moving slowly, and then run to the fast one after it goes off.
3: Subtract is just the move that reduces your HP. The circles will always add to the number you have while you remain in the circle. The thing he casts after it are the rules. You need your number to be evenly divisible by the number stated or a prime number. If your number already fits(he says prime and your number is already 2) you can just stay out of the circles. Remember that 1 is not a prime number.

As far as I know, there didn’t seem to be any text or audio cues or cast bar for the insta death tidal wave, you just have to look at the boss to see which way he’s getting the water from and stand on the opposite side of that. Personally I find this kind of awkward and a little difficult to see since for me the water jug is not in view in any normal way I would generally have my camera positioned to be able to see everything that’s going on. I think this mechanic always happens a few times in a row after everyone gets knocked back. So if you get knocked back and then don’t see any cast bars check for his water jug positioning.

For the clock one I’m pretty sure you want to ,I’ve imto a tile with a slow moving clock first because the fast clock tiles explode first. So once the fast clock tiles explode ,over into the now safe space.

For the number one, if you have 5 and he says divide by 3 you can step in the 1 circle to make 6 since 6 is divisible by 3. My issue was that I didn’t really understand what he was saying. Just replace “divide by” with “divisible by” in your mind and it all becomes clear

I got confused by the simple math part because I didn't know stepping on the circles added to my number. I assumed I had to use them to divide whatever the crap the boss wanted.

Famfrit gathers water before he shoots out the Tsunami, you will see a lot of water gathering in the direction he will shoot it out to.

The faster moving clocks explode first, then the slower moving ones shortly after.

Worker 7 drops your health down with Subtract and he spawns 4 circles with 1, 2, 3, and 4 dots over them. They will add to your HP the amount indicated by the dots when standing in the circles.
Then you need to use grade school math to figure out how much you need to add to your HP to get to the number he says, or a multiplication of said number.

The only thing that you shouldn't be shameful of not knowing if you're above 9 years old is Prime Numbers, which seems to always be the first one of the second set of maths... And Prime Numbers are numbers that can only be divided evenly by itself and 1... The relevant ones are 2, 3, 5, 7, 11, 13.

1.) The water one (I forget his name). Had this really big water aoe that I just seemed to love getting caught in. Did you notice any visual or written cues for when this happens, or how it'll be aimed, etc?

Watch which way he points his ewer. You can also tell by which way he draws water from--he'll always shoot it back out in the same direction.

This is the only mechanic in the entire raid that I legitimately hate because it's so hard to see as a melee. The boss is simply too tall to get a proper view of the ewer high above his head without having to angle the camera awkwardly, even with max zoom.

2.) Gigas, I forget the name of the spell but all of the tiles become clocks. How does this one work?

Each tile is a "clock" with a spinning hand. Some spin fast and some spin slow (they always alternate, like a checkerboard--all adjacent tiles will always been opposite of the one you're standing on). Naturally the fast ones explode sooner so stand on a slow tile and as soon as any of the fast ones explode around you go stand in the now safe tile before the slow ones explode.

3.) Construct 7 I HATE THIS ONE. He summons 4 # platforms (1-4) and changes your HP. My HP was turned to 5 so, like, everything he said just didn't work. :| What do you think about this one? If your HP doesn't pertain to any of the things he says, should you stay out of the platforms or...?

It's simple math. He casts Subtract which sets your HP to anything between 1 and 9. Standing on one of the four pads temporarily adds that amount of HP to your health for as long as you're touching it and you use those to manipulate your HP to "answer" his divisibility questions (so standing on Pad #3 when you have 2 HP will set your HP to 5 for as long as you're touching it).

ex: I have 3 HP. He says "Divisible by Five!". I go and stand on Pad #2 that gives me 5 HP and I stay there until the cast is finished.

Alternatively, if your base HP is already "correct" you don't have to use a pad at all (even if you could use the pads to answer).

ex: I have 4 HP. He says "Divisible by Four!". I could run all the way to Pad #4, but as my HP is already "correct" without the pad I can safely stay out and continue to hit the boss while still passing the mechanic.

Side note: Please don't be one of those people who think 1 is a Prime number.

He aims it in the direction he draws water from, but the issue is that sometimes you can't see because the waterspouts obscure it.

This really helped, thanks everyone!
