The maul ability is potentially very powerful.  It allows you to keep attacking until you miss.  Each attack is at -3 accuracy.

Either -3 is not much, or that aspect is bugged.

My character, Lady Tarth will usually get at least 3 or 4 attacks, and quite often keeps attacking until the creature is dead.

She was able to kill a slightly wounded Abelix (sp?), lord of the earth in 1 round.  I didn't keep track until about 16 attacks into the round, but she kept going for about fifty attacks.  These were for about 4-6 per pop, with an occasional crit for 10 or so.  Her grand total was 229 hp in one round. 

She also took a out a death demon in one round.  It had about 109 hp.

She does have a high dex and accuracy, so it should be good, but with this weapon in its current state, she is unstoppable.

ps I'm loving the beta so far.
