Im for this idea, and why not another reason to implement armor advantages cloth has no decay, plate has 100% decay kinda thing helps mages and people who need it and would thematically makes sense. Or if you have a staff decay doesnt happen since that more thematically shows yes i wanna play a mage vs cloth armor. I think one of the issues with focus is the sheer amount of it you can get i feel it would be very balanced if i couldnt get 500 on a level 3 character with 16 focus and 3 rings my mage build was ready and had 500 focus i think the amount per focus level should just stay 10 per till a soft cap and the rings should maybe give 50 or have an rng roll like the others flat 100 this is insane.
Plus not to mention when everything is %based it goes off total and with such inflated numbers this gets out of hand fast. In my playtime the only thing that felt truly “busted” was cone shot but i wrote about that and why it litterally was broken in another post. I think the system as is is good but with a lil tweaking will be great. I also agree focus attacks should not charge focus. But an enchantment could roll on staffs to say gain x% focus on dmg like they allready have giving mages a leg up for their playstyle.
