GMS:CrimsonWood keep 2,Magatia coming soon

You're just assuming things are possible in the game's structure when that's not necessarily the case. An attack that does varying damage depending on distance may not be possible based on what we know of how monsters work.

I did provide an alternative in case it wasn't possible. Varying attacks for close/far range.

and the difference between a totem and an attack is that a totem would move at a predictable pattern, and attacks can't be like that. We wouldn't know when the attack would be coming around again.

Then how is this done? With a longer animation, it shouldn't be too difficult to recognize an archer-rape attack and move out of range in time. Unless you're right next to the boss.
