I have no complaints (only praise, actually).
Re: sneak attacking, a two-prong approach will probably nip that in the bud. First, you remember to cite the correct damage dice in your post. Second, I print off a copy of Guran's character sheet and reference it during combat (hopefully triggering me as your failsafe to remember the correct sneak attack dice). I regularly pull up everyone's character sheet during combat, so it's helpful to me if the sheets are kept up to date.For the sake of fuller disclosure, I should elaborate: most of any inadequacies of use of Guran's traits are probably my own fault.
I mean, Guran is 3rd level, so his Sneak Attack should be 2d6, and is listed that way in the Rogues' Gallery; but the last time (or two? or three?) that I had him roll SA, I used 1d6 instead. That's simply sloppiness on my part.
If Guran is going to become a better example what a Moradin-worshipping dwarf should look like, he is going to have to work at it.
For future advancement -- are we going to be using Feats? Multiclassing?
If we're using Feats, I could try to make Guran a little more devout by having him converse more with Father Spec, perhaps on the subject of theology, and on what it feels like to be a cleric; then, when Guran gets one more level in the Rogue class, he could take the "Resilience" (WIS) Feat, gaining +1 WIS (raising that score to a 14 instead of a 13), and gaining Proficiency in WIS saving throws.
Does that sound like a way to go? With will and effort, Guran could partly overcome his merely ordinary Intelligence somewhat, and perhaps become a better example for others.
Both Deafness and Silence are on the Cleric 2 spell-list, which [Spec] can cast.
