As you select your clan, you unlock the clan’s unique passive ability. By spending Ability Points, you can then unlock abilities from the Ability Tree, starting with your chosen clan. Ability Points are earned when completing missions, combat and exploration. When you’ve unlocked all abilities for a clan, you can unlock the clan Perk, a permanent passive upgrade for those dedicated enough to unlock all abilities for a clan.

Corrosive Touch

Clan Passive: Bodies will dissolve away after being fed on.

Cauldron of Blood

Torture your victim by boiling their blood slowly from the inside, making them drop to their knees screaming. Nearby enemies/civilians are drawn to their screams.

Recall

First Use: Mark your current location with a ward.

Second Use: Deconstruct yourself, and explosively reconstruct yourself at the marked location obliterating any enemies standing in that spot.

Blood Curse

Curse a victim. The next time they take damage, their body swells horrifically and they explode, doing damage to all around them.

Blood Salvo

Conjure a set of blood daggers that can be thrown at enemies.

Greed

Clan Perk: A chance when feeding, that the last used ability receives twice as much blood, increasing the rate you can perform abilities.

In Vampire: The Masquerade - Bloodlines 2, you can play your character in different ways. Tremere are a ranged, glass-cannon type, and the clan abilities are focused around supporting that playstyle. We want it to be straightforward playing a clan, and this is therefore not an ability optimization game where you have to go through a multitude of abilities and weigh them against each other.

For those who prefer a more advanced playstyle,  you can customize your playstyle by visiting important Seattle vampires that are sworn to assist the Sheriff (you) , including offering their Blood to help unlock abilities from their clan. Abilities from other clans may cost more AP depending on how well they align with your clans Disciplines. The Tremere Disciplines are Auspex (the supernatural ability to become aware of more than meets the eye), Dominate (the power to mesmerize and control the actions of others) and Blood Sorcery (the ability to control blood with your arcane knowledge). If another clan has a Dominate ability not part of the innate Tremere kit, it would cost less AP to unlock than an ability for a Discipline Tremere don’t have, such as becoming faster which is a part of the Celerity Discipline. Clan Perks stack, and unlocking several elevates your power much closer to elder level.

In contrast to the activated abilities and Clan Perk which can be learned from the other clans, your clan passive can not. This means that you can combine features from other clans in hundreds of different ways, but your Tremere playthrough will remain unique from playing as another clan who branches into Tremere abilities.
