Totems can be used to reset monsters and bosses. This makes them extremely useful for skoll to avoid him raging at 1 minute. So you no longer have to resort to only using a reset class. You can also apply this to archivist. See my video on Archivist solo with fire trap reset, you could use the totems to reset him instead of the traps if you don't have the rogue charm.
Yes, but its not that great - skoll has 25% dam resistance, which = approx 16/17 armour, so on skoll it would reduce to about 13 (full stacked) taking him down to around 22% dam resistance. So probably better to use alfar axe or something.
