Class and ability spoilers ahead.

Elven Fencers have Evasive Impetus, and I tried to use the boots of Vengeful Impetus but apparently "when this character is attacked" doesn't count if they evade or Evade. Thieves can't equip the Parry Buckler, Guarding Impetus relies on way too low of a guard rate/phys def, Grave Impetus relies on allies dying... Wereowls only give disappearing PP. Passive Miracle only gives PP. Using Passive Gift they can give allies PP, but it costs 2 - not really a huge problem, but if there's no one to grant them AP for doing so then it doesn't really accomplish what I'm asking. The only staff I know if that grants AP is Active Heal, which costs 2AP. Painbringer is unique to Berengaria. Nigel's got Advance Cover, but again it's a guarding ability and unique to him.

Is there anything I'm missing, or is it just not meant to be?
