I feel the need to reiterate this, the max percentage for any stat is 19%. NOT 20. Bloody christ, can people read.
The way the 19% is added to your existing stats. Is by whatever stats you currently have. Say you’ve 500 heat, the 19% is of that total.
19% of 500 = 95. So that’d be your total. Any decimals are rounded up, regardless of how high or low it is.
incase anyone needs some facts
