Your listed skill modifiers (Stealth +6, Perception +8 etc) are comprised of (a) the relevant ability modifier, and (b) your proficiency bonus, assuming you are proficient in the skills. Your proficiency bonus is setby your character level, which is the sum of levels in all of your classes. Yours will be +3 since we are all 5th level.
So Perception is 3 + Wis bonus, whic I assume is 20.
When rolling such a skill as Stealth, it is an “opposed check” which means the DC is not fixed, but another cereature makes a roll with a relevant skill modifier (Perception in this case).
So you have +16 Stealth (including +10 for Pass Without Trace). To use the skill, you roll 1d20 + 16. Say you roll 12; your Stealth total is 28.
The creature you are trying to hide from uses Perception to try and detect your movement. Their DC to do so is your Stealth roll, so 28. The DM will have their Perception modifier listed under Senses, and will roll d20 + that modifier. If they can’t beat 28 there is no chance of him succeeding.
The trolls won’t be a problem, though hopefully they don’t have any wargs or winter wolves. These evil canines have advantage perception with olfactory. A full blown troll lair is fairly likely to have some sort of evil wolves.
A clean cantrip (Prestidigitation) right before sneeea-king in combined with Pass without trace & invisibility and Elf Boots and Elf Cloaks though is going to be hard to beat.
Thanks MHaye.
(Can you tell I’ve not played 5e before and don’t have the manuals? )
OK, let me see if I’ve got the hang of it.
At 5th level all characters get a +3 bonus to every Proficiency Check.
For a specific Proficiency (e.g. Stealth), look up the character’s associated ability (here it’s Ghan’s Dexterity of 16 - which is another +3.)
Thus Ghan is a basic +6 on Stealth.
His Pass without Trace spell adds another +10, giving +16 modifier whilst the spell lasts.
When trying to use Stealth, Ghan rolls d20 + Stealth modifier and the DM compares that to an opponent’s d20 + Perception modifier.
So it’s more dangerous to sneak past a) high level opponents b) opponents with high Wisdom (or Olfactory skills.)
Pass without trace has a range of “Self” which means that Ghan can only cast it on himself.
The effect radiates out for 30’ from the caster. So for Felareth to benefit, he’d have to stay within 30’ of you.
The best solution seems to be for Ghan to scout, having cast Pass Without Trace and with Invisibility - which Felareth has to play his mandolin to cast.
You only add the proficiency is skilled in the skill.
So High level/powered creatures with Perception are tough to sneak past.
The Wisdom adds in no matter what, so high wisdom is a big help to perception, especially passive perception.
Many creatures with strong olfactory have Advantage with perceptions. So my winter wolves as an example are +5 perception, but advantage for olfactory.
So Ghân would be a d20+16 with the pass without trace but the Wolf would get to take the higher of 2 d20 rolls +5. But just after a magical cleaning I would remove the advantage. So just a d20+5.
Ghân’s worse roll is a 21 so the Wolf needs a 16+ to notice Ghân sneaking by if on active guard duty.
Now a Passive Perception is a 10 base + Perception. So only a 15. Any wolf not on guard would never notice Ghân
Trolls are not wise though they are oddly preceptive. A generic troll is usually +2 perception and a Passive of 12. But watch out for Black Trolls (Olog Hai) they are +6 for a passive of 16. Still not a major problem for Ghân though in this scenario.

Interesting, we might be misusing Pass without Trace.
We interpreted the 30’ radius to just mean at the time of casting. But rereading it, your interpretation looks correct. We’ll go with yours for this game.
Another reason why it might be better for Ghan - or indeed anyone but Felareth - to scout is movement. Felareth has a speed of 25’ while most humans and elves have a speed of 30’. That means it’ll take less time for them to get anywhere.
Thanks for the replies.
Looks like Ghan’s Pass without Trace being personal means that he’s the Scout!
So if there’s a bunch of opponents in one place, do they each get a roll?
Thus if a Wolf on Guard needs a 16+ to notice me, what if there are two Wolves on guard?
Also how does the Princess feel about lending Ghan her Elvish items?
