The Lorekeeper

The Lorekeeper典籍守护者

Lorekeeper is the boss of the Sunken Library legendary location.

Equipment

• The Black Book黑书.
• An Ancient Attire (60).
• An Ancient Headpiece (80).

Skills

Behavior

Lorekeeper has a very complex behavior. The most important things are that he can't die if any Phylacteries命匣 remain intact and will respawn from them, and the fight gets harder when you destroy more Phylacteries.

Some 一些Ancient Honor Guards古代荣誉卫士 will guard him, not actively attacking you and making the battle easier.

His Miasma and Horror have to range limit. He has no zone of control. He can traverse steep cliffs (verify).

Variables

• Let ${\displaystyle f}$ be the number of remaining Phylacteries.
• Let ${\displaystyle r}$ be the round number.

Skills availability

Lorekeeper's skill set is defined by ${\displaystyle f-{r \over 7}}$:

Summoning skulls

Lorekeeper can summon Screaming Skulls尖啸骷髅 once per turn. Skulls spawn 5-6 tiles away from your brothers. To simplify, he summons 4-12 skulls per turn to a limit of 12-30 on the map, depending on how many Phylacteries were destroyed.

Exact mechanics:

• Let ${\displaystyle x=\max(0,9-\max(0,f-{r \over 9}))}$.
• Summoned per turn: ${\displaystyle \min(x+4,12)}$.
• Limit: ${\displaystyle 2x+12}$.

Summoning apparitions

In the middle of battle Lorekeeper starts summoning Apparitions, ghostly copies of himself. They spawn far away from you and will cast spells too. To simplify, there will be four of them as it's not worth spending time hunting them.

Exact mechanics:

• Summoned per turn: ${\displaystyle \max(0,6-\max(0,f-{r \over 9}))+2}$.
• Limit is 4.

Lightnings

Lorekeeper can mark a vertical line on the ground to strike it with lightnings on the next turn. Apparitions also do it, but with one turn of cooldown after the actual strike. There can't be more than 3 simultaneous lightning strikes. Brothers in zones of control, horrified惊恐 brothers and lines with many brothers are prioritized. Lightnings have no friendly fire.

Geomancy地术

It is the Lorekeeper's ability to raise and lower earth to protect Phylacteries and himself from melee, and comes in two forms. One-time version is used earlier and does not affect the Lorekeeper himself. Normal version affects him and has two turns of cooldown, so he casts it on every third turn, even if it's disadvantageous for him. If he dies, all raised ground lowers.

Exact mechanics:

• One-time Geomancy condition for raising ground: ${\displaystyle f-{r \over 9}\leq 6}$.
• One-time Geomancy condition for lowering ground: ${\displaystyle f-{r \over 9}\leq 5}$.
• Normal Geomancy condition: ${\displaystyle f-{r \over 9}\leq 3}$, has 2 turns of cooldown.

Raising undead

In the middle of battle Lorekeeper will read the Black Book黑书 he carries, raising all resurrectable undead. Lost Treasure Hunters迷失的寻宝者 are always resurrectable, and Honor Guards are resurrectable if not decapitated. A Warscythe战镰 or, if there is an item in the off-hand, Khopesh镰形剑 also will be created if the undead has no weapon. Armor won't be repaired. Apparitions will cast Raise Dead like Necromancers亡灵法师 and will not create any weapons.

Exact mechanics:

• The Black Book condition: ${\displaystyle f-{r \over 9}\leq 6}$and at least 6 corpses on the map.

Tips

• Don't hurry to destroy Phylacteries as soon as you can, you will only make the fight harder. Try to destroy all Phylacteries at once or at least quickly to reduce the time of Lorekeeper being the most powerful.
• Bringing him to low HP and staggering allows to skip the difficult phase entirely, if you destroy all Phylacteries on that turn and kill him.
• Killing him may seem pointless, but it lowers Phylacteries to the ground to destroy easily.
• Decapitate斩首 Honor Guards with cleavers to prevent reanimation, or replace their weapons with weak ones.
• Spiked Impaler刺桩重弩 can knock him down from a pillar, however his high ground gives you a penalty of -30 to hit.
