Bogling roots are items which drop from boglings in Teldrassil. They give
you +1 damage and last ten minutes.
Boglings only spawn at the conclusion of two quests, both involving quest-giving plants:
Strange fruited fronds
Shimmering fronds
They only spawn a % of the time in the second quest. There are three boglings, who each
drop a root.
Since the shattering the bogling root buffs are not supposed to be stackable. However, if you
split the root stacks up using shift, they stack infinitely. I tested with 53 of them and had
a buff for each, so I doubt there is any max limit.
+1 damage isn't a lot for most classes because the buff applies on a per attack basis, so
you need a class with very fast attack speed. Feral druid is probably the best, though it
is possible a rogue or something could do better with slice and dice which maximizes
attack speed.
53 roots turned melee dps of 92 on my feral druid in cat form to 206. That's a pretty major dps
increase. With enough roots you can theoretically one-shot anything.
Farming the roots isn't that easy unfortunately, as these are one-time quests, so max 6
per character. However, there are ways to cheat: the boglings can be killed any one so
you can camp the quest turn-in point and steal other people's roots. Often noobs don't
wait for the quest conclusion and wander off, so you can take the roots with a clear
conscience.
Bogling roots could also be purchased on the AH, or purchased indirectly. If you just want to
farm them yourself it takes about 5 mins with looms as a night elf to get to level 4 (minimum
level for the quest) and turn-in quest, so it would take you about an hour to farm 60 working
flat-out.
