The Evility Shop, later renamed to Skill Shop, is a facility introduced in Disgaea 3: Absence of Justice. It allows the player to spend a unit's Mana to purchase skills, skill boosts and Evilities.
Buying Skills[]
Only available in Disgaea 3 and 4, where Weapon Mastery is replaced for Weapon Forte, and Weapon Skills and Spells aren't learned naturally.
Elemental and healing spells need to be bought in ascending order of power.
Enhancing Skills[]
Boosting an attack skill in Disgaea 4.
- Enhance/Boost Power: A function that increases the potency of a skill but also increases its SP cost. Most skills can be boosted up to 9 times, and there is an option to reduce the boost level of a skill in case it became too expensive to use.
- Disgaea 3 and 4: Boosts grant a multiplier to the Power of attack/healing skills(applied after additive bonuses). In these games, skills with variable range/area gain a new area with each power boost and 1 more panel of range every 3 boosts.
- Max power boost in D3: x550% for offensive Spells, x145% for healing Spells, x640% for most other skills.
- Max power boost in D4: x320% for offensive Spells (x385% when Giant), x145% for healing Spells, x640% for all others (x800% when Giant).
- Disgaea 5 and 7: Boosts usually increase the Base Power of attack/healing skills by +7% (exceptions will be noted in their respective data tables).
- Disgaea 6: The max boost level in this game is 9,999, so there's an option to buy multiple boosts at once. Power boosts are once again a multiplier, reaching x250,000,100% on level 9,999. If you lower a skill's level, raising it back up to any level that had already been reached will cost no Mana.
- Disgaea 3 and 4: Boosts grant a multiplier to the Power of attack/healing skills(applied after additive bonuses). In these games, skills with variable range/area gain a new area with each power boost and 1 more panel of range every 3 boosts.
- Enhance Range: Introduced in Disgaea 5, as power boosts don't increase spell area and range anymore. Despite the name, it actually only increases the area of effect.
- Enhance Proficiency: Only in Disgaea 6. This option can be used to increase Skill Levels. Like with power boosts, it's possible to buy multiple increases at once.
Buying Evilities[]
Characters can purchase additional Evilities, and even sell them back for half their original Mana cost (changed to a full refund in Disgaea 6). Each class has a few personal Evilities they can unlock for purchase, but there's also a selection of generic Evilities available for multiple or even all classes.
With the introduction of Class Proficiency in Disgaea 5, all characters can unlock Evilities that normally correspond to a Generic class, including its Unique Evility if the class is fully mastered.
Create Scroll[]
Introduced in Disgaea 6. This allows creating a Secret Scroll with a copy of an Evility known by a character. The Mana cost is simply the same as buying that Evility.
In Disgaea 7, this option needs to be unlocked through a Dark Assembly bill.
