Daemon Mace?

As far as melee weapons that I have available, Daemon Mace seems to have been the best weapon I have so far (and the only Rt Melee Weapon I have/use). I was wondering, how could I improve this weapon with tune-ups, since I haven't the slightest clue on weapon tunes.

daemon is really weird as a standalone melee

The problem about demon mace is the time between its attacks during the combo. High TGH enemies, even medium TGH enemies will be able to attack back after each hit and probably stun you and also interrupt your combo. Luckily Demon Mace has no cooldown, so this shouldnt be a problem... but yeah. The AOE of the first attack in combo looks big, but unfortunately it isnt. The second attack is very slow and has only a short hitting time and also misses like 80% of the time, while the last attack in combo pushes the enemy away and is slow like a normal mace.
I also dont know how to tune that...
