Where is there enough space to kite over land? I eventually managed one over water but took a good 45m, anything to cut that down would be nice.
If you go the area where you can enter Temenos, there's a couple of decent sized chunks of land. I don't know if they're big enough for solo kiting, but my friends and I manaburned Yovras there.
Here's a link where Kaeko discusses his solo experiences with Yovras. He mentions one fight taking 12 minutes. Maybe you'll find some tips there that will help shorten your fights.
