A Casual Stroll to Mordor reports on how the improved skills function in play. These include the ability to stack up to three Burning Embers DoTs on a target, the combination of two Signs of Battle powers into one Wizard's Fire, a nice 10% buff to pet damage through Sign of the wild: Rage, and a much more versatile Improved Staff Sweep.
There's also word on the new Lore-master pet: a Limrafn. While Lore-masters were originally slated to receive an Auroch pet, apparently the common complaint about the pet's size ended up swaying Turbine's mind. The Limrafn is a floating ball of light that doesn't attack, but instead assists the Lore-master in the off-healing department.
Lore-masters will also see one of their lesser-utilized trait lines -- Keeper of Animals -- given much love in the form of tempting abilities and buffs.
