Gvaz: It took me a few times to get the mechanics down but basically this is the fight.
- The coiled front tentacle will not strike, the other one will, run or roll out of the way.
- Run over to tentacles with globes and place them approx where they'll land and run around in that area until it smacks down, roll away at the last second you should be fine
- it will get stuck and smack the orange thing as fast as you can (fast works fine) with a silver sword
- when it rears back, it's either spitting poison or it's whacking with both front tentacles so stay away from the front. If you get stuck, mash RMB and roll away. it will usually try to crush you with both tentacles.
- you only really need to cut three tentacles before the platform collapses
- if you've laid down Ydren, then put up quen. the shield can sustain a single blow. Keep it up as often as possible
- don't get too close to the sides of the beast, even though they have globules, they'll smack you for major damage and throw you in front of the beast, usually to get hit by tentacles
- if you hear something about "watch out!" or that he's gonna throw rocks around, get near the wall and he wont hit you
- if you need a second to get a breather, you can press the "Pause/Break" button to "pause" the game. Press it again to step forward a second like you would on a movie. press LMB to resume. You can't move around or look around in this mode. (also useful for cutscenes or when you want to take a screenshot)
- When the bridge falls on it, run on it quick and dodge the tentacles and get to the top of the bridge. Geralt throws a bomb (that he apparently pulled from thin air, idk where he got it) into it's maw, destroying it.
Fight over.
I cut off 3 tentacbles, i ran for the way out but it wouldn't let me climb the rock, instead the boss grabbed me and through me into the wall.
