I've been thinking: wich one is more efficient generally? and in specific cases?
While DA deals normal/elemental damage, the WRM (warmaster rocket hammer) deals pure elemental, for more details, here are the status of both weapons:
DA -> http://wiki.spiralknights.com/Divine_Avenger
WRM -> http://wiki.spiralknights.com/Warmaster_Rocket_Hammer
I have both; but personally I prefer Hammer because:
1. It out dps DA and 5* Brandish for normal attacks << cant stress this enough
2. Dash is op and is fun as hell
3. Using the hammer has a high risk of death; but I like risks and challenges. So its natural for me to prefer the Hammer.
The disadvantages of Hammer is that:
1. Dash is glitchy, but you'll learn how to adapt to the dash when you use the hammer properly.
2. Dash does 1/2 of the maximum dmg output of the hammer. So if you don't use the dash to attack foes; then you might as well use DA.
3. Charge attack is aoe based, but with shorter overall range then Brandishes and DA and leaves you vulnerable for a longer period of time compared to brandishes and DA.
4. Hammer does less dmg to foes who resist elemental compared to Brandishes and DA.
Therefore; Hammer (normal attacks) are better on single targets. DA (normal attacks and charge attacks) and Brandishes (charged attacks) are better on crowds.
