  Spell Charges are reservoirs of prepared magic a Magician keeps ready to cast. The small gems on your charge display show how many Charges you hold, sorted into tiers.
<~><~>  Every spell lists a minimum Charge tier on its page. The higher your Magician's level, the higher the tiers you can hold and the more Charges you keep at once.
<~><~>  Casting a spell spends one Charge of its tier, and spending that Charge draws Mana a single time. The uses, shots or duration a Charge grants afterwards cost no further Mana; only the first draw from a fresh Charge touches your pool.
<~><~>  Spent Charges refill slowly on their own, the higher tiers taking longer to return. When a tier runs dry you must wait for it, or fall back on a weaker Charge.
