i was looking at a friends pet and saw that it has 12% universal resist and asked him if it was proof (is there a universal ward?) and he said it was, the highest proof I’ve seen is 10% with jewels
Spell Proof is a talent that usually caps off at 10%. But it can be boosted beyond 10% if the pet has a particularly strong selfish talent that increases Strength and/or Agility.
There are some PVP pets that have max 260 Agility and 260 Will. (As in, you must be a PVP commander or warlord in order to get and equip that pet.) However, hatching with a pet like that can result in regular pets having higher than usual stats and again, talents like Spell Proof can be boosted higher than usual.
