Ensanglion the Calamity was replacing Michelia and now has replaced King of Doom Phono (EpicFest). This unit is playable in v14.1.1.I of Battle Dogs.
This fast, tough enemy stands at 350 range but slowly fires off highly devastating attacks that reach up to 550 range, weakening any survivors to 50%. Freeze, Slow, Waves and Surges all have no effect on him, and while vulnerable to Knockback effects, that does help in skipping his very short backswing. Combined with his low knockback count itself and any support in play, getting to this enemy may be easier said than done. His main weakness is that his attack animation's foreswing is quite long, meaning he isn't all that difficult to stall in the end as you can potentially interrupt the attack for a window of opportunity.
