Cyclopean, Olympian, and Jotunheimian prefixes stack with the weapon quality modifiers (exceptional, elite, celestial/primordial/infernal) in a linear fashion. These prefixes add +2 to the base damage multiplier while the quality modifiers add +1/+2/+3 to the base damage multiplier. Thus, a Cyclopean elite weapon deals 5x base damage (1+2+2=5).
Mythic affixes cannot appear on double-headed and triple-headed flails.
