Build for fast colosseum clears? WAD regions

Hello. I was wondering what would be the best build(s) for fast colosseum clears? I'm currently 40/40 pacts with King's barrage and the flask, but the waves take a long time and being a noobie like me doesn't help either.

My regions are Wilderness, Asgarnia, and Desert.

Notable gear I was able to gather so far is:

- Full void

- Full Bandos, Armadyl + Torva body

- All wildy weapons

- Max avernics, Echo boots

- Eye of Ayak, Staff of the dead, full Virtus and Dagon'hai

- Masori mask and legs, as well as fang and Elidnis' ward.

The way I understood from looking some things up, you need to have Kandarin for all the thorns and water mage builds, but then again, I might be wrong as this new demonic pacts skill tree remains intimidating for me. Do you guys have any builds you are willing to share?
