Understand damage absorption and the limits of servitor protection.
Against another playable attacker, CP absorbs damage before HP unless that damage bypasses CP. Ordinary monster attacks hit HP directly. Example without shields or transfers: 700 damage with 500 CP removes 500 CP and 200 HP.
Transfer Pain needs an active transfer effect and a servitor within 1,000 world units, including height. Transfer is capped at the servitor current HP minus 1, before the owner CP absorbs remaining damage. At 50%, 1,000 damage and 101 servitor HP transfers only 100, leaving 900 for the owner before CP.
The five ordinary Transfer Pain levels transfer 10%, 20%, 30%, 40% and 50%. It is a toggle with MP upkeep, not a permanent passive reduction. These values describe the five unenchanted Interlude levels.
