 * Owns the Ability System Component and the AttributeSet, so abilities, effects and

 *
 * - ASC replicates in Mixed mode: the owning client gets its own effects (needed for
 *   predicted cost and cooldown), other clients only get tags and cues.
 * - Net update frequency 100: ability confirmations ride on this actor.
 * - StartupAbilities are granted once, on the server, in BeginPlay.
