Question about Double XP weekend

[runescapeplayyer]

do you get double XP for combat XP such as hitpoints and str?

And will I get double the XP per lobster that I fish?

 

[cotonpk3r]

it goes by a staircase of tapering xp multiplication values.

So at first you'll get 10.8 xp per 10dmg you do. (2.7x the 4 you usually get)
then after 30 mins it will step down to 10.2 xp per 10dmg. (2.55x)

A full list of the xp multiplier stairs can be found here:

and to the part about the lobs.. yes you'll get bonus xp per lob you fish. The amount will depend on the timing as stated above

 

[Determinate]

Yes, and yes.

Not exactly, double, but multiplied by your base xp modifier.

 

[BEYOND REASON]

I think it would be better if after the first day the multiplier resets.
