I really like that this has AI. But still, the map has a lot of room for improvement, for sure. Let me list all of those possible improvements as I can remember them:
-Either the arena seems to be too tiny, or the knockback effect too powerful. The fight often ends with just by hitting your enemy once or twice with the breath of fire spell into the acid. For this issue, I would either recommend making the arena bigger, or decrease the knockback effect of the spell.
-Make the camera view higher. The default camera view seems to be too restrictive and it's hard to keep up and scroll around since the players tend to fly around with knockbacks. Playing with a higher camera view will be a lot easier.
-Divide the gameplay into fight sequence and market sequence. This is very important. It's almost impossible to analyze items and buy them and react to enemies at the same time, especially when the enemy resurrection cooldown is so short, too.
-The map definitely needs more spell variety. For example, you can make a "purchasable spells" system like in Warlocks, where you can buy and upgrade new spells with the gold or wood you got from the kills.
-This is a minor thing, but the AI seems to know where you are even when you have Windwalk active.
That's all for now. Like I said, I really am happy that this map has AI, which is something that Warlocks really needed. All you need to do now is, build upon that feature, and take heed to the suggestions.
