General Description:
Dreg'ora has very high energy for a kha'rall (usual is about 45), but all of his stats are fairly weak. He has water (big surprise), and no mc (another big surprise), but unlike the original 4 kha'ralls, Dreg'ora has a more, interesting ability.
When a creature is in combat with Dreg'ora, they lose 10 energy for each of their disciplines that are below 30. This ability can be extremely deadly against elementalist with, weaker stats, but there are more things you can do with this ability.
Strategies and Gameplay:
The first immediate combo that comes to many player's minds is pairing him up with Part'soa. Just play a few water attacks and your opponent will struggle to survive. If 40 energy loss isn't enough, you can use a super rare attack called rancorous projection for another 40 dmg!
Now you have to start wondering, what happens when Part'soa is cannoned to death? Well, there are other ways to reduce disciplines. One rare M'arillian mugic, Intimidating Melody of M'arr, can be devastating to opponents against Dreg'ora. The battlegear, Ulmanator, reduces all of the opposing engaged disciplines by 10 for each elelment they have. 2 attacks, Riptide and Degenerative, also help lower disciplines, but my favorite option of stat reduction has to be the location Glacier Plains, M'arrilian Melting Camp.
Ways to Counteract It:
Dreg'ora, unfortunately, is easily hit for big damage. He can't do anything to remove elements, and his low stats will cause him to be hit hard by discipline specialists. LVBSOA eats this guy up for lunch, as well as anyone whose stats are crazy high (Blazvatan, Maxxor PoP, etc.).
Artwork
Dreg'ora himself is quite ugly, but the artwork is well done. You can just see him squeezing the life out of the poor Danian. I could also imagine him choking Fivarth...
Pros
Nice high energy for a Kha'rall
Access to Shards which can raise his already high energy
An ability that can end battles with many creatures quickly.
Cons:
Low Disciplines
Really bad against high discipline creatures
LVBSOA eats him up
Overall Rating:
I'd give Dreg'ora a 6/10. The M'arrillian can be really powerful when used correctly, but you have to devote so much to him to get him to that power level. Without the support, he just can't justify his worth for a slot in your army.
