I have noticed that if your weapon is already at level 10, then any heat collected in the dugeon is a waste and cannot be used for anything else. Maybe towards the end of the dungeon, you might be able to transfer the heat to another knight by killing yourself over and over again. But, that is not really helpfull when you are doing a dungeon solo.

Use heat for the run if not needed!!

so then why not think of a way to use the heat during the time we are going through the dungeon. for example, why not put an option to use the heat as a way to move faster and increase the knight speed as a speed boost.. The speed boost does not have to last that long, but it can last for 5 to 10 seconds. Another way to use the heat is to store it for another armor. the storage can last for 2 days limit, but if i for example put on the worng armor or wish to transfer the heat to a newly made armor. it may feel like the run i did was not only to get crowns, but to transfer my experience to another armor.

The spped boost can be used to dodge attacks and get through the dugeon faster. I would like to call the speed boost overburn or something that has to do with a release of heat lol. anyway, theirs a lot more ways to think of to use heat, but i just dont like the feeling that the heat function besides for your armor is a useless funtion that cant be incorperated for other means. Variety equals more fun, at least i think so, the more functions, the harder the gameplay, more intresting the game will get. :)
