Skill Stone

A rare trinket that reduces the mana cost of class abilities via ClassManaCostReduction. Skill Stone lets you cast your class-specific skills more frequently — a meaningful boost for any class whose identity depends on repeated ability use. Part of a mana-reduction pair alongside Mind Stone; the two likely function identically or with minor differences. Essential for high-ability-frequency builds running mana-heavy classes.

ClassManaCostReduction specifically targets class abilities rather than all spells, so it complements but doesn't replace general mana reducers like the Chip set. The exact reduction amount (flat or percentage) affects how it scales — a flat reduction benefits low-cost skills proportionally more, while a percentage cut benefits expensive class abilities most. Combine both to minimize total cast costs in ability-heavy classes.

Mage, Wizard, and Cleric builds where class abilities form the core offense or support kit benefit most. Stacking Skill Stone with Mind Stone for double cost reduction can dramatically increase cast frequency per fight. Less impactful for Fighter or Tank builds that rarely use class abilities as their primary attack vector.
