Buying an ability in The Blood of Dawnwalker does not put it in Coen’s hands. Skills you pay for sit dormant until they occupy a slot, and the number of slots you have is itself a perk you have to purchase at a Shrine. That two-step setup catches a lot of players out in the first few hours, especially when a freshly unlocked Vampirism power refuses to appear in combat at night.
Quick answer: Interact with a Shrine, open Perks, and buy the slot perk for the tree you want (Forbidden Sigils, Master Fencer, or Vrakhiri Might). Then open the menu, go to the Active Abilities tab, and double-click an unlocked ability to place it in a Day or Night Quick Slot.

What you need before an ability can be slotted
Three things have to line up. The ability itself must be unlocked, you need a free slot in that ability’s tree, and you need to be in the right part of the day cycle to edit that loadout.
Unlocking works differently per tree. Swordmastery and Witchcraft skills usually require a Manual, found while exploring or bought from merchants, before you can spend a Skill Point on them. Vampirism skips manuals entirely and gates its abilities behind Corruption, which rises when you drain blood with Voracious Bite in Vrakhiri form and through certain quests and Phials of Blood.
Skill Points come from leveling up and from quest rewards. A green arrow next to the health bar tells you one is waiting to be spent, and you can only spend it while standing at a Shrine.

| Tree | Slot perk | How to reach it |
|---|---|---|
| Witchcraft | Forbidden Sigils | Work through the Unnatural Resilience branch and obtain the Forbidden Sigils Manual |
| Swordmastery | Master Fencer | Work through the Sustained Focus branch and obtain the Master Fencer Manual |
| Vampirism | Vrakhiri Might | Raise Corruption to the required level; no Manual needed |

| Rank | Slots | Cost | Corruption (Vrakhiri Might only) |
|---|---|---|---|
| 1 | 2 | 1 Skill Point + 1 Time Segment | Level 4 |
| 2 | 3 | 1 Skill Point + 1 Time Segment | Level 7 |
| 3 | 4 | 2 Skill Points + 1 Time Segment | Level 11 |
Fully ranked, each tree tops out at four abilities. That is also the ceiling for a quick slot bar, so four Active Abilities per type is the most you can carry into a fight.
Equip abilities from the Active Abilities tab

Day and night loadouts are edited separately
Coen keeps two independent bars, one for daytime and one for nighttime, and each can only be changed during its own half of the cycle. Trying to rearrange your Night Quick Slots while the sun is up will not work; wait until nightfall, or use the Wait option at a Shrine to move the clock.
The split matters because usage is time-locked too. Vampirism abilities like Blood Surge and Piercing Shriek only fire at night, most Witchcraft abilities are daytime tools, and Swordmastery works around the clock. Build the day bar for sword work and hexes, and the night bar for claws and vampiric powers.
Swap abilities when slots are full
There is no drag-and-replace shortcut. When every slot in a tree is taken, double-click an equipped ability to remove it, then double-click the replacement to slot it in. The freed space appears immediately, so you can reshuffle a whole bar without leaving the menu.
Note: ability slots and quick slots are not the same thing. Slots control how many abilities from a given tree Coen can have equipped at all, while the quick slots decide which of those are mapped for instant use in combat.
Passives and free abilities that ignore the slot limit
Not every ability behaves like a button press. Passives including Adrenaline Rush, Swiftness, Shred, Unholy Vitality, Crimson Rush, Cycle of Ruin, Scarlet Shield, and Walking Fortress cost nothing to use, but they only function while equipped in the Active Abilities panel. Leaving them unslotted means their effects simply never trigger.
A handful of abilities are exempt from the slot cap entirely. Shapeshift, Mercurial Fervour, Voracious Bite, Death from Above, Astral Communion, and Compel Soul do not take up a common slot, so unlocking them never costs you room for a combat skill.
If an ability won’t equip
Only a few things block the process. The tree may be out of slots, in which case you need to un-equip something or rank up its slot perk at a Shrine. The ability may still be locked, waiting on a Manual for Swordmastery and Witchcraft or a higher Corruption level for Vampirism. Or you may be editing the wrong bar at the wrong hour, since day and night loadouts each require their matching time of day.
Because slot perks cost both Skill Points and Time Segments, it is worth deciding early which two trees you actually intend to lean on rather than spreading points thin. Four ready abilities in a tree you use every night will do more for you than a scattering of half-filled bars across all three.
