How to Burst Xaolan

First thing you need here is SP armlet. I know they are rare and expensive - but otherwise you will get onli 1-2k xp with 1 wall made on burst.
I bought one swift scroll wish gives spd 75 and MaxSP 400.

Next step is how to set up your remote. Because i am using earth char to burst with Xaolan. I def in ever turn. No need to waste time and food on her bursting because she is already lvl 108 reborn and won't get any xp from burst. The problem is when Xaolan can't rest her sp after battle. So i set up on player to heal her sp when is lower than 200.

If you use water or fire to burst with Xaolan must use other steps. There waters must to at least shrink turns. And is better if don't make water shield. Because Xaolan's wall miss on wate shield. Sometimes if she is lucky she wall the water's pet first so then water's shield miss.
And fires must at least do their GS and atk turns when they brust pet.

And then you need to have luck with your brust teams. Best is to burst in your own team. But not much people can afford that kind of training.
Xaolan get like 2-7k xp without double. It will take a while to reach level 100. :)
Good luck!
