Yeah. The idea is that you grab, dealing damage, but the question was whether or not combining the garrote with another Rogue at-will power would automatically grab the target.
The answer is no. The garrote can only be used as a grab attack. It seems that subsequent damage can only be inflicted with further grab attacks unless you have training. The initial attack, however, looks like it must be a grab action in either case.
Concerning the line in Garrote Training that says, "If you are a rogue, you can use the garrote with the Sneak Attack class feature and any rogue melee attack power that can be used with a light blade." IMO this means that once you have grabbed the enemy, you can use the garrote in combination with SA or any other rogue at-will power to inflict further damage and effects. This is actually pretty powerful since the feat also penalizes escape attempts and grants CA for the duration of the grab.
Is this right?
