Cost Analysis

Gold Value

• 225 health =  600
• 300 mana =  420
• Total Gold Value =  1020

Gold Efficiency*

• Catalyst of Aeons' base stats were 92.73% gold efficient.

Strategy

• With the increased durability and sustainability it provides, Catalyst of Aeons allows champions to remain in their lanes longer without needing to recall.

Trivia

• The word Catalyst means something or someone that precipitates or causes an event to happen without being used up itself, referring to the item's passive effect.
• Catalyst mana restore is applied after resistances. The higher your resistances the less mana you will regain from damage.
• Shields are treated the same as normal health for the damage to mana calculations.
• The name "Aeons" may be a reference to the Star Craft map Aeon of Strife, by Aeon64, which was the spark that began the MOBA genre.
