In RPGMello, your Magic and Trickeries are chaotic and random. You have a spell deck and a trickery deck, which you draw from during battle.
Crafting your deck
Your base spell deck size is equal to your Spirit + your Level. Your base Trickery deck size is equal to your Wits + your Level. They can consist of any spells or trickeries that you have unlocked via Feats.
Spell Cards and Trickery Cards that you have found or bought on your travels are not added to your deck, and are one-time use.
Your deck can contain an amount of duplicate cards depending on the card’s rarity, shown in the bottom right corner of the card. For example, if a card has Rarity 2, you may only have two in your deck. Your discarded spells shuffle back into your Spell and Trickery deck at the end of a long rest.
Your Turn
At the start of a battle, shuffle all of your decks. At the start of each of your turns, draw a card from any deck until your hand reaches your hand size (your Wits). During your turn, you can use any spell cards in your hand for an action, as well as the magic cost shown on the card.
When cards are used, they are put in your Discard pile. After finishing a long rest, recover all discarded cards.
You may also spend an action to topdeck a card and immediately use it, but only once on your turn.
Mental Strain
Should you not have enough magic to cast a spell that you use, your magic is used, the remaining magic cost is taken directly from your health. Regardless of how much damage you have taken this turn, excess damage taken in this way causes one Mental Injury. If you survive (even if downed), the spell fires off like normal, otherwise, the spell fizzles. This is treated as a mental injury - as such, you recover 1 Spirit and Wits each long rest.
Regaining Magic
The Focus Magic action can refill your Magic, up to your Spirit.
Card Range
All spells have a maximum range equal to your Spirit stat (a creature with a Spirit of 3 will have a spell range of 3 tiles).
All trickeries have a maximum range equal to your Wits stat (a creature with a Wits of 4 will have a Trickery range of 4 tiles).
Take 10
Taking 10 allows you to search any of your decks and use a specific card. This process takes 10 minutes, and the card is consumed like normal. The GM can rule that using a card in this way can have a much more substantial effect.
