Lords Mobile Familiar Battle research: every research, cost and time

Familiar research is split across two trees. Familiar Battles holds the Familiar Battle Slot researches, Familiar Offense, the Familiarity researches for each troop type's attack, defense and health, and the Gym Training and Pact Merging Speed lines. The Familiars tree covers the everyday side: Anima harvesting and storage, the Pact researches and merging costs, Gym Membership and Skill EXP Boost, and the second-tier harvesting researches for each resource.

The whole tree in numbers

43 researches and 376 levels in total. Finishing every level takes 30,034d 12h 29m at base speed and gives 220.82M might. The resources add up to 2.34B food, 1.03B stone, 948.1M timber, 1.1B ore and 1.75B gold, plus 1,156 Technolabes. The longest single research is Familiar Offense, at 3,508d 6h 4m from level 0 to the maximum.

A research-speed bonus divides every time here: real time equals base time ÷ (1 + bonus ÷ 100), so a 100% bonus halves it.
