heroes have stats which are:
deity--> when hero engages in battle attack power is increased
devil--> when hero engages in battle defense power is increased
light--> increases resource output when choosen as an archon
shadow--> speeds up processes when choosen as an archon
as for flagships u need blueprint which can be aqcuired by: 1.) treasure box 2.) defeating boss in NPC zone 3.) buying from other players (u need sky points for that, your lucky if you buy one without sky points)
note: default hero flagships cannot be emplaced and the flagships you made cannot be revived. its bye2x so be careful and i suggest making defensive heavy flagship
