Are you interested in how your stat bonus changes while looking at combat reports? If so, reading the article below can give you more interest in your growth. Most stat bonuses are sum operations. For example, research, chief gear, hero gear, etc In this article, I would like to inform you that there are two exceptions to the sum operation. In conclusion, Exclusive skill and Buff item are not sum operations, but sum operations + multiplication operations. In other words, a 20% attack buff item increases your stat bonus by +20% & *20%. I’m trying to prove what I explained through the screenshot below. I hope you will be more interested in games and wars as you read them.
