!!!Well, firstly I want to tell you, that this is only for Rogue Robe!!!
What do we know about Rogue:
- Smoke bombs - Teleport backwards
- X-Bow - Poisonous darts
- Speed boost - Fastest Robe
- Low Life - Weakness

And now the combo :

Take QRQRQRDE (Ice,Ice,Ice,Stone,Shield) and cast it on yourself.
Now take Haste (ASF or Lightning,Arcane,Fire)

Now - simply rush into enemies. 1 hit = approx.~ 2500 dmg ice. Almost instakill for every enemy. Why this happens? Because Haste on Rogue gives you almost flying speed - so your Ice/Rock shield emits Ice damage that is does normally.

I will put up a video when I do it (somehow).

Also you can do this on normally speed robes with knife of counter-striking (found in Ep 5) + Haste.

*note: If you don't use the D (rock) in the armor it will not penetrate armor and it will be doing less dmg (this appears to be awesome, because you can also kill not-yet-materialized deamons in Ep 6).
