Adding to post #646:
Memory Mentor
At this location, a hero can "forget" some skills and abilities and choose a different path of development. "Forgetting" abilities is a process opposite to gaining levels: a hero can choose any number of skills and abilities, but only if they are not necessary conditions for obtaining the remaining skills and abilities.
The cost of "forgetting" depends on the hero's level and is equal to 500 * [square root of (Hero Level)] (rounded up) per "forgetting."
Sacrificial Altar
"Evil" heroes (demon lords, necromancers, warlocks, and barbarians) can sacrifice creatures in exchange for experience. "Good" heroes (knights, rangers, mages, and rune priests) can sacrifice artifacts.
Experience is calculated using the following formulas:
For creatures: Experience = 3 * [Total Hit Points]
For artifacts: Experience = 0.5 * [Artifact Cost]
Note that in "Lords of the Realm," all heroes, regardless of alignment, can sell their artifacts for the same half price at city markets.
Arcane Library
In the "Arcane Library," you can buy high-level spells for rare resources. The type of resource depends on the magical school to which the spell belongs:
Dark Magic spells are sold for mercury
Chaos Magic spells are sold for sulfur
Light Magic spells are sold for crystals
Summoning Magic spells are sold for gems
4th-level spells cost 15 units of resources, and 5th-level spells cost 25 units. A hero can only buy spells that they can learn. The selection of spells in the "Arcane Library" changes every month.
Fortuitous Sanctuary
The "Fortuitous Sanctuary" gives the army a bonus for the next battle. The type of bonus depends on the day of the week:
Monday: +3 to Attack
Tuesday: +1 to Morale
Wednesday: +3 to Defense
Thursday: +1 to Luck
Friday: +1 to Initiative
Saturday: +2 to Attack and +2 to Defense
Sunday: +1 to Speed
A hero cannot have two or more bonuses from the "Fortuitous Sanctuary."
Astrologer's Tower
In the "Astrologer's Tower," heroes can see what effects the next two weeks will have and even replace one of them with the effect of the current week. Changing the week costs 6000 gold; each player can only do this once a week, and not on Sunday. The effect will take effect the next day. If several players order a change on the same day, one effect, randomly selected, will take effect.
Mother Earth Shrine
In the next battle, the health of all creatures in the hero's army will increase by 10%.
