Molten Armaments (DK) does not increase Weapon Crit chance on the casting DK for 6 seconds. At least not in an additive way, wasn't tested if it is current weapon crit x1.27, but it clearly isn't Weapon Crit + 27%, as it was tested with a base of 0 that remained 0 on the character sheet. Several (over 40 with each ability affected by weapon crit) attempts to crit with weapon attacks and Molten Whip and Unstable Flame were absolutely unsuccessful during the first 6 seconds of the spell's effect. With a crit chance of 27%, the probability of having 0 crit hits after 30 hits is 0.00008.
It was not tested whether or not it works on allies, but it definitely does not count "self" as an affected target, which it should to be consistent with other skill descriptions in this game.
