Answered and can be closed :D

From what I can gather there appears to be a certain random element which can mean you can fail (or only perform satisfactorily) on missions even with higher stats - its my understanding that the higher stats just help to mitigate the randomness element.

Have you put all her proficiency points into increasing Strength? You can allocate more than 10 proficiency points to Strength increase as you can use more than one different proficiency type - it took me awhile to work that out - so I figure it might be worth mentioning.
(Actually, I mis-calculated and Un-named will only have 10+ proficiency points when she gets to level 55, before that point there's only 10 points maximum for allocation. Something to keep in mind, I suppose.)

You might also want to looking into equipping Relics, Armour and Accessories which focus on Strength to give yourself a further boost.

Jillyana,

I think you might want to double check the stat required for the mission.... Pretty sure "an ox at heart" is a dexterity mission, not a strength one. My dexterity pet is doing that mission now. =/



Wander,

To a certain extent, there is a random element that decides how well you'll do for a mission, but for a level 25 mission, 350-400+ of said stat definitely should not result in a fail. Much less if it is 600+ like Jillyana's pet is. The random element is mostly seen when the pet's stat is around the value that can pass the mission.

Thanks for the clarification Wonderfulb2uty :)

I just looked as the quest was reopend again, and now it says dexterity is needed. I could have sworn it said str as I acepted it. However maby a glitch or a mistake from my part. Sorry for taking everyones time but thank you for the info :D

no worries. had that happen to me before and I got really confused. =P

Glad I could be of help. =)
