Found wandering around with the other Twisted mobs at roughly 18k, 20k.
Tuliros is a named Twisted Sylvan and shares all their traits including thier fast attack rate and 20-ish point damage add.
It conned yellow to me as a 37 Valewalker. Dropped nothing but minor coin upon death.
Faction changes from killing Tuliros:
Standing with Olcasgean - Decreased
Standing with Z'zozicck Zhxizzckrkk - Increased
Standing with the Tree of Ages - Increased
Standing with The Watcher - Increased
Standing with the Outland Residents - Increased
Standing with Krrzck - Increased
