new pet abilities and how to get them

[Vinceh]

So far I've been able to get a Hyena that has the 'Rip Tendon' ability which is a 9 sec 50% slow on a 30sec CD.
According to datamining there should be spiders in the game that learn a 'Web' spell at level 12 that roots for 4 seconds but I haven't been able to find a spider with that ability, did anyone else have any luck in that regard?

I did a whole tour around the zones we have right now and the only spider that had the 'Web' ability was the 'Moss Stalker' you can find in Silverpine Forest.
