Kingdom Rush Origins (Steam) Impossible Hero Challenge - Beheader's Seat Campaign

I was worried about this map going into it.  Not so much for the waves themselves, although they're no slouch, but for the boss.  He has the shortest boss path in the game, and DPSing him down before the exit is non-trivial - especially for our DPS-poor heroes.  However, in the end he proved no match for our superior tactics.  The key proved to be stalling him with troops and our hero in between two Wild Magi, as well as investing in Golden Longbows around the rest of the map that can also contribute to the effort.

These tower selections are pretty crucial for this map, not just for the boss, but also for the waves, as it lets us invest in both Eldritch Doom and Crimson Sentence on those towers, giving us several insta-kill abilities spread across the map.  In the last few waves the number of big enemies - Ettins, Blood Ogres, and Ogre Magi - gets overwhelming, and you really need to take several of them down with insta-kills.  It's not really possible to set up a "normal" choke point with an artillery tower on the right exit lane.  For one, you need towers that can target the multiple waves of Perythons, and for another, a single Bladesinger tower plus an artillery tower is just not going to be enough to take down all those mobs.

Impressions

While challenging, this is yet another map in the "standard hard" category.  Hero performance is important here, but slightly less so than perhaps on other maps, so most of our heroes ended up with 'A's.  Having a ranged attack to help with the Perythons proved the difference between 'A' and 'B' for some heroes.

In the end only Eridan, Catha, and Razz earned 'C's, and again it's their low DPS that put them at the bottom.  This is one of those maps where there are a few areas where you really need to burn down some mobs before more appear (like killing a continual stream of Blood Ogres so they can't transform gnolls), and they really struggled with them.  Maybe it was just good RNG, but I had less trouble with Arivan, so he managed to pull a 'B'.

Final Grades

• Eridan - C
• Arivan - B
• Catha - C
• Reg'son - A
• Prince Denas - B
• Razz and Rags - C
• Bravebark - A
• Vez'nan - A
• Xin - B
• Phoenix - A
• Durax - A
• Lynn - A
• Bruce - B
• Lilith - A
• Wilbur - A
• Faustus - A

Best Choice

Phoenix and Wilbur tie here for Best Choice.  There are lots of heavy streams of mobs on this map, so Phoenix's AoE is fantastic, and Wilbur just DPSes everything into oblivion as usual.
