I am glad that you enjoyed it!
And yeah I didn't want chat to do a lot of damage, so I made chat a debuffer, and item machine for the final boss lol, the idea with the arrow sign weapon was also it only being useful when you use the speed skill, but since you only get it after beating the boss in the third area, you don't have any time really to familiarize yourself with that skill and you probably don't think about the arrow sign since it's literally useless before it, but at least the speed skill was actually very useful when I tried beating the last boss with default weapons only, since the last boss can hit like a truck its valuable to be able to heal before it attacks.
