It's projectile type is Demon.

Those fast fireballs work fine in reptiloid highlander demon resource. What about taking projectile behaviour from there and modify it slightly?

Well its more of a pimped out Reptiloid, Arachnoids do hitscan you just need to actually pay attention instead of just dodging.

Oh...I had increased speed/jumping when I tested it. Too bad it's just another arachnoid-like enemy in that regard.

Remember, HD Fireballs are a BITCH if you don't keep track of where it's going otherwise you'll get 20 HP shaved off, just simply take the easy route and kill the Fiendian as Fast as Possible, Bio helped me with these suggestions just track it.

I thied fighting it alone. When the fireball has flown past me and is returning, then it seems to explode on an impact, making me take damage no matter how hard I try to avoid it.

Plus it kinda always does that in HD too if your not careful.

I've noticed problems with it's projectiles sometimes explodig a bit too much so I made it invunerable except to Cannon balls, you just need to check if its coming to properly dodge it.

Currently its fireballs are very hard or impossible to dodge when they're on a return trip. Also, it seems that they don't explode on non-inclined walls unlike in the original.

oh nice, on the screenshot it looked like the SSC but nice! Gonna get it now :)
