Hi,
It appears the Cabi RR5 isn't working as intended.
The spell is called 'Resolute Minion' and the delve reads as:
'The effectiveness of Stun, mesmerize, snare and root spells on your pet is reduced by 100%'.
When using the ability in RVR, the pet can still be rooted by VW frontal root style.
Based on the description, I think this shouldn't be the case.
I don't record my game play but happy to find a VW to organise a fight with to test live if you need.
Thanks,
