Pin is useful early game to get a space between you and a monster (regardless of its speed). Whirlwind is also okay for giving weapons pseudo-cleaving.
You should be using lunge against basically everything since 1) It has a damage bonus and 2) it front-loads a lot of damage if you get a double-hit, especially with serpent lash.
I have not entirely figured out how to best use wall jump. It does front-load a lot of damage since you will attack everything about 3 times with a mindelay of 7 auts (i.e. if you can kill the monster in 3 hits you may kill it before it has a chance to damage you). It's pretty good with serpent lash.
Use serpent lash a lot. It's WJC's most powerful ability and is fairly cheap. Assuming a 7 aut mindelay (most weapons), you are making an average of about 3 attacks with a damage bonus that never miss,
instantly. This can also be done to multiple enemies.
You can lunge and whirlwind at the same time if monsters are in the right spot. Example with some hapless orcs:
- Code:
..o..
...o.
..@o.
.....
In this example moving up would whirlwind attack both of the orcs on the right and lunge attack the orc above them. With a 7 aut attack delay this means you would do an average of 4.3 attacks by making that move. Do recall that this can be done instantly using a serpent lash move.
Fun fact, attacks done while lunging cleave. If the above example was done with an axe, the player would get an extra attack on the middle orc.
