Defeat "Zaartax" using only helm, armor and necklace. 200aps, title [Aquatic Slayer].
Clear "Rahabkor Lair" dungeon with 4 players using no weapon. 300aps, furnishing "kraken's Head".
Clear "Rahabkor Lair" solo, healing only with your skills (no pet/potions allowed). 250aps, furnishing "Kraken's Tentacle".
Clear "Rahabkor Lair" avoiding death from Pink circle curse. 150aps, title [Tentacooler].
Clear "Mecharydon Lair" without having a single enemy get a reflective shield. 300aps, title [Shark Tamer], furnishing "Pool of Sharks" (would be a furniture version of the Mecharydon pool attack).
Clear "Ekenta Lair" without any party member being affected by Ekenta's reflect aura. 200aps, title [Merman Slaughter] "Merman's Club" (would be a replica of Ekenta's weapon).

Campaign aps (aps of a specific expansion) could be kept in a way they can only be achieved if the player completes the campaign under specific conditions such as clear all the expansion maps within x time, complete each of the expansion maps while wearing 1-5 items released during the expansion, Kill all the enemies on each of the expansion maps, etc.

Could add aps based on farming/crafting valuable items for whatever expansion is currently active and once the expansion is over these aps wouldn't award points but cosmetics.
For aps that require farming "x" item I would suggest adding a counter that guarantees looting said item after "y" amount of runs.

Aps should focus on clearing "x" content under "y" conditions and/or obtaining important stuff from each expansion just like Aged set, Planar Pendant, Glint set, somberholt points, etc.
Maybe having these kind of aps points count only for the duration of their respective expansions, once the next expansion gets released these aps would only give a title, banner, furniture, etc.

Recopilation of "feats" aps I suggested on the fiasco achievements "feedback" threads.
