Snake dancer attempts to dodge cinder and sear tiles, and I assume the other tiles as well, considering wide AoE cinder/sear tiles like Sear and Fire breath, it makes no sense from a viewer's standpoint, I propose that cinder/sear tiles ignore snake dancer completely.
This seems like a bug to me, but I could be wrong. Agreed regardless.
I'm just going to assume its not a bug as Snake Dancer is working as intended, but this would be a lovely change.
Field effect damage from Sear/Cinders/etc can no longer trigger Evasion or Cobra Dancer. Note that field objects such as bombs, traps, and 'on hit' impact damage can still be avoided by these skills.
