This bug relates to the combo that includes the abilities: Impulse Drive, Disembowel, & Chaos Thrust.

When using other combos such as: True Thrust > Vorpal Thrust > Full Thrust, we are presented with a special effect over the ability guiding us to which ability to use in order to complete the combo, effectively granting the affects stated in the ability the description.

However with: Impulse Drive > Disembowel > Chaos Thrust, the combo effects state in the ability description rarely, if not me never, occur such as disembowels piercing debuff or chaos thrust's damage-over-time debuff. Also there are no guiding graphics as describe earlier. Is this because the combo effects are CHANCE, and if so why is that not described adequately in the ability description, or is this combo mechanic completely broken? This is sorely effecting my damage output, please tell me what is wrong here. Thanks
