Wyverns give me 210 slayer xp per when the bestiary says they have 200 hp.

 

 

 

Also, lvl 158 wyverns don't have a page.

Slayer XP is NOT always equal to HP. Skeletal wyverns are one of these monsters for which that applies. Don't worry 200 is the correct HP and 210 is the correct Slayer XP.

 

 

 

Also, level 158 wyverns...? As far as I know, the only wyverns are level 140. I'll check the cave and see if Jagex added new ones, though.

 

 

 

EDIT: Apparently they do exist! Also, I had to kick one to death to respawn it to make certain I had the correct HP. Ended up getting to 8 HP and teleporting the moment I killed it, then had to trek all the way back! (This time I took an Abyssal whip. Mwahaha!) Naturally, here is the monster examine. All data about them is the same except for combat level (HP, Slayer XP, examine info, etc).

 

 

 

The new monster can be found here:Skeletal Wyvern -2-
