no, li lanci al livello minimo
usando la tua CD da warlock
e per muro di fuoco devi restare concentrato
e mentre lo fai puoi usare il bastone per picchiare gli altri, anche a 2 mani se sei inxxxxato 😉
Spells DMG p141
Some magic items allow the user to cast a spell from the item, often by expending charges from it. The spell is cast at the lowest possible spell and caster level, doesn't expend any of the user's spell slots, and requires no components unless the item's description says otherwise. The spell uses its normal casting time, range, and duration, and the user of the item must concentrate if the spell requires concentration. Certain items make exceptions to these rules, changing the casting time, duration, or other parts of a spell.
Many items, such as potions, bypass the casting of the spell and confer the spell's effects. Such an item still uses the spell's duration unless the item's description says otherwise.
A magic item, such as certain staffs, may require you to use your own spellcasting ability when you cast a spell from the item. If you have more than one spellcasting ability, you choose which one to use with the item. If you don't have a spellcasting ability—perhaps you're a rogue with the Use Magic Device feature—your spellcasting ability modifier is +0 for the item, and your proficiency bonus does apply.
