Completely 0 debuff

No idea then.

Dude In a public tomb he sat on bes eping him while he was awake, like godmode or some shit?

There used to be a client which would reduce damage taken by 50% permanently, but I am pretty sure god mode would auto kick.

What's the IGN of this guy?

Well he probably just updated the codes for all debuffs (Including the server-sided debuffs)
The noclip is probably the sprite noclip code edited to work for Oryx's castle.
Although, if he indeed get dc'd after noclipping, I guess that shows that some dungeons do have some noclip parameters to disconnect you. and Sprite World doesn't.

^ auotaim for spell would be sort of nice for not movin stuff (like skulls), but since the spell start from the centre of a tile, a movin target would be just lagtastic.

Conventional wisdom says this is true. However, the reason spells start from the center of a tile is due to the screen coordinate to world coordinate function. The position sent out to the server doesn't have to be the center of the tile.

I have a client with 0 Debuff xD But to not get the paralyze kick, you have to take a the HP Hit, But not the paralyze

Well if you think about it, the map for Sprites is randomly generated, and there are no walls, just the unwalkable check thing that acts as a wall. But as you run the entire map can be discovered. For o1's castle you need to break barriers to move forward. Oryx's Castle map is a set layout that the server just drops people into groups.
A quick question to anyone who revisits this thread, if you try to noclip through a wall into black space/room in something like a Snake Pit, do you automatically get d/ced? Someone brought it up before but I'm not sure which thread.

You do not get automatically disconnected, it'll let you say for a second or two, and then it disconnects you.

i forgot his name
