" First and simplest were multi-runes. Multi-runes were the most common type, and they both looked and functioned much like typical runes, just with lots of lines to incorporate different features. The most common multi-runes included capacity, recharge, and a single function of the same type. A basic example would be a rune with a regeneration function, a life mana recharge feature, and a life mana capacity feature. The rune for this would look like a regeneration function rune, but with an extra line for recharge and the extra bracket-looking lines around it for capacity. There would also be lines to signify the levels of each, if it’s a higher-than-Quartz enchantment. "
