Sorry for the Repost. I originally posted, then afterwards saw the template. I deleted the original post and used the template. However, the template did not seem to work, so I am reposting again.
Some pet are getting an Agility buff for food rather than Grit. Agility used to give armor bonuses, but it was changed to Grit. However, not all pets were changed to receive this Grit/Armor change. For example, the dog pet ‘Aries’ is getting agility as a buff instead of grit. Trying to feed Aries pork gives him a 14% agility bonus, which is useless to the pet, where what is wanted is 14% Grit bonus, so the pet has a better change at getting grit for the armor bonus. This problem was noticed in a few other pets and Horses as well.
Several other pets have the same problem where some foods give the agility buff when it should now be grit (agility is absolutely useless to a pet that does melee damaage, which is the majority).
*The situation would seem that all npc followers need to be reviewed and updated to make sure that food was properly converted to the grit armor buff change.
Greetings XEnigmaX!
Thank you for reporting this issue to us.
In order for us to properly assess this, could you please let us know in which server is this happening please? If you’re playing on an Official Server, is this also happening in your Singleplayer or vice versa?
We’ll be waiting for your reply!
This issue is happening on a private server. The problem has been noticed with other pets, for example, I trained a greater rocknose and it has agility as food buffs instead of grit, and where agility is useless for this pet as it is a melee/tanky pet. I also noticed that agility has not been converted from some thrall perks. For example, I have a thrall that reached level 10 and earend the “Barrens Traveler” perk. “Living in the exiled lands has hardened your follower, granting them increased health and agility.” This perk should now be grit…as agility no longer ‘hardens’ the follower by enhancing armor rating.
By private server, I mean an online server company where one logs in on the internet, not a local LAN or single player game.
