By fine-tuning the way you upgrade Bill’s skills and gear, you can save yourself quite some valuable and limited resources in the process and as not all skills have the same amount of impact but have the same amount of costs leveling up, fine-tuning them is worth it in the end.
Important! If you want to check how well Bill does in the current meta of all heroes in Top Force, please check out my current tier list of all heroes here.
Here is a quick overview of the rankings of Bill for the different modes of the game. Please refer to the full tier list linked below to see the ranking of all heroes in Top Force and full evaluation and priority.
Bill’s Optimal Gear Setup(s)
Now we have to take a look at the gear setup, as it takes a lot of time and resources to craft higher rarity gear and not all gear is as impactful as the other one and you have to gear a couple of heroes in Top Force. Also upgrading gear gets very expensive and you simply can’t just pump all your Alloy and Ore randomly on gear.

Bill’s Optimal Skill Upgrade Order
Upgrading skills is possible after you get Bill to 1-Star and then you will be able to upgrade each skill in 5-level increments. While the first skill levels are rather easy and cheap, it will start to eat quite a bit into your Skill Medals and as you can’t produce them, you might end up with half-built heroes. So, here is the order you should work on the skills for Bill so you only spend the Skill Medals where they actually provide good value.
