Warlocks are a class of character that uses magic to fight enemies. This magic comes in the form of spells, which are used to deal damage or to protect allies.
Warlock spell slots are important because they determine how many spells a warlock can cast at once.
Warlock spell slots are divided into three categories: active, passive, and triggered. Active spells are the ones that a warlock can cast right now. These spells require mana to use, and they can be used to deal damage or to protect allies. Passive spells are the ones that a warlock has already cast and are still active.
These spells don’t require mana to use, but they can only be used once they’re activated. Triggered spells are the ones that a warlock can cast, but they require an event to happen first. These events might include things like getting hit by an enemy or taking damage.
Warlocks have a limited number of spell slots because they need to keep enough mana available to cast active and passive spells as well as triggered spells. The number of spell slots a warlock has is determined by their level, which is determined by their character level plus the level of their class.
Warlocks also get an extra spell slot at level 10 and another one at level 20. This means that a warlock usually has between four and six spell slots at level 1, six to eight at level 10, eight to ten at level 20, and up to twelve at level 30.
